Description

[Technical Field]

[0001] The present disclosure relates to an information management device and an information management program. [Background technology]

[0002] There are known devices that send questionnaires about products or services to users and receive their responses. For example, Patent Document 1 discloses a device that sends a questionnaire about a service that provides a gift to a gift recipient, receives the responses, and acquires various information. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-101387 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-described device conducts a single questionnaire for gift recipients. However, since a sufficient number of responses to a single questionnaire are not always received, the device may miss an opportunity to obtain more useful information. Therefore, the information management device and information management program according to the present disclosure aim to obtain more useful information from respondents to the questionnaire. [Means for solving the problem]

[0005] An information management device (1) according to one embodiment of the present disclosure includes a first information sending unit (10) that sends first survey information regarding a first survey about a product or service to a user, a first information receiving unit (11) that receives first answered survey information regarding a first answered survey, which is the first survey answered by the user, from the user, a second information sending unit (12) that sends second survey information regarding a second survey about the product or service to the user that sent the first answered survey information to the first information receiving unit (11), and a second information receiving unit (13) that receives second answered survey information regarding a second answered survey, which is the second survey answered by the user, from the user.

[0006] An information management program (P) according to one embodiment of the present disclosure causes a computer (C) to function as a first information sending unit (10) that sends first survey information regarding a first survey about a product or service to a user, a first information receiving unit (11) that receives first answered survey information regarding a first answered survey, which is the first survey answered by the user, from the user, a second information sending unit (12) that sends second survey information regarding a second survey about the product or service to the user who sent the first answered survey information to the first information receiving unit (11), and a second information receiving unit (13) that receives second answered survey information regarding a second answered survey, which is the second survey answered by the user, from the user.

[0007] According to at least one of the information management device (1) and the information management program (P), by sending a second questionnaire to a user who has answered a first questionnaire about a product or service, it is possible to obtain further information that the user has not answered in the first questionnaire, thereby making it possible to obtain more useful information from the respondents to the questionnaire.

[0008] In the information management device (1) according to one aspect of the present disclosure, the second information transmitting unit (12) may transmit the second questionnaire information to a user when the first answered questionnaire related to the first answered questionnaire information received by the first information receiving unit (11) satisfies a preset transmission condition. This makes it possible to further obtain information that was not answered in the first questionnaire from users who have desired characteristics among the users who answered the first questionnaire.

[0009] In the information management device (1) according to an embodiment of the present disclosure, the first questionnaire may include an item related to an evaluation value for a product or service, and the transmission conditions may include a condition related to the evaluation value. In this way, it is possible to select users to whom the second questionnaire is to be sent based on the evaluation results clearly indicated by the users as evaluation values.

[0010] The information management device (1) according to one aspect of the present disclosure may include a first output unit (14) that outputs user-specific answer information in which user information about a user, first answered questionnaire information sent by the user and received by the first information receiving unit (11), and second answered questionnaire information sent by the user and received by the second information receiving unit (13) are mutually associated. This makes it easier to understand the trends of each user in the content of answers to questionnaires.

[0011] An information management device (1) according to one aspect of the present disclosure may include a coupon information sending unit (15) that sends coupon information related to a coupon to a user before the first answered questionnaire information is received by the first information receiving unit (11), and a coupon granting unit (16) that grants a coupon to the user on at least the condition that the first answered questionnaire information sent by the user has been received by the first information receiving unit (11). This allows the user to be made aware of the content of the coupon, the conditions for granting the coupon, etc., before granting the coupon to the user.

[0012] An information management device (1) according to an embodiment of the present disclosure may include a first response rate acquisition unit (17) that acquires a first response rate calculated as the proportion of users who received first answered survey information by the first information receiving unit (11) among users to whom first survey information was transmitted by the first information transmitting unit (10), and a second response rate acquisition unit (18) that acquires a second response rate calculated as the proportion of users who received second answered survey information by the second information receiving unit (13) among users to whom the first survey information was transmitted by the first information transmitting unit (10) or users to whom the second survey information was transmitted by the second information transmitting unit (12). This makes it possible to grasp the proportion of users who will respond to the survey.

[0013] An information management device (1) according to one aspect of the present disclosure includes a coupon information sending unit (15) that sends coupon information related to a coupon to a user before the first answered questionnaire information is received by the first information receiving unit (11); a coupon granting unit (16) that grants a coupon to the user on at least the condition that the first answered questionnaire information sent by the user has been received by the first information receiving unit (11); and a first coupon granting unit (16) that grants a coupon to the user on the condition that the first answered questionnaire information sent by the user has been received by the first information receiving unit (11), calculated for each content of the coupon as the ratio of users who received the first answered questionnaire information by the first information receiving unit (11) among users to whom the first questionnaire information was sent by the first information sending unit (10). The system may include a first response rate acquisition unit (17) that acquires a response rate, a second response rate acquisition unit (18) that acquires a second response rate calculated for each coupon content as the proportion of users who received the second answered survey information by the second information receiving unit (13) among users to whom the first survey information was sent by the first information sending unit (10) or the second survey information was sent by the second information sending unit (12), and a second output unit (19) that outputs coupon-specific response rate information in which the coupon content, the first response rate calculated corresponding to the coupon content, and the second response rate calculated corresponding to the coupon content are associated with each other. This makes it possible to grasp the relationship between the coupon content and the proportion of users who respond to the survey, thereby obtaining data that is useful for examining cost-effectiveness.

[0014] An information management device (1) according to one embodiment of the present disclosure includes a target first response rate acquisition unit (20) that acquires a target first response rate, the target value of which is calculated as a proportion of users who have received the first answered survey information by the first information receiving unit (11) among users to whom the first survey information has been sent by the first information sending unit (10), and the target first response rate is calculated based on a number of target users, an expected second response rate, and a target second number of responses, wherein the number of target users is the number of users to whom the first survey information has been sent by the first information sending unit (10), the expected second response rate is an expected value of the second response rate calculated as a proportion of users to whom the first survey information has been sent by the first information sending unit (10) or users to whom the second survey information has been sent by the second information sending unit (12), and who have received the second answered survey information by the second information receiving unit (13), and the target second number of responses may be a target value for the number of users who will receive the second answered survey information by the second information receiving unit (13). This makes it possible to grasp the target response rate for users to the first questionnaire, thereby obtaining data that is useful for considering measures to achieve a required response rate.

[0015] An information management device (1) according to one aspect of the present disclosure may include a coupon information sending unit (15) that sends coupon information related to a coupon to a user before the first answered survey information is received by the first information receiving unit (11), a coupon granting unit (16) that grants a coupon to the user on at least the condition that the first answered survey information sent by the user has been received by the first information receiving unit (11), and a coupon amount obtaining unit (21) that obtains an estimated second response cost, which is the monetary value of one coupon granted to the user by the coupon granting unit (16) and is an estimated unit cost required to receive the second answered survey information by the second information receiving unit (13), and an estimated second response rate. This allows an appropriate coupon amount to be estimated.

[0016] The information management device (1) according to an embodiment of the present disclosure may include a total coupon amount acquisition unit (22) that acquires the total coupon amount, which is the total value of coupon amounts of coupons granted to users by the coupon granting unit (16), calculated based on the number of target users, the target first response rate, and the coupon amount. This allows the budget required for issuing coupons to be estimated.

[0017] Note that the reference numerals in the parentheses above indicate the reference numerals of components in the embodiments described below as an example of the present disclosure, and do not limit the present disclosure to the aspects of the embodiments. [Effects of the Invention]

[0018] In this way, the information management device and information management program according to the present disclosure can acquire more useful information from respondents to the questionnaire. [Brief explanation of the drawings]

[0019] [Figure 1] FIG. 1 is a block diagram showing the configuration of an information management device according to this embodiment. [Figure 2] FIG. 2 is a diagram illustrating an example of variables used in the total coupon amount acquisition process. [Figure 3] FIG. 3 is a flowchart showing the survey implementation process executed by the information management device. [Figure 4] FIG. 4 is a flowchart showing the total coupon amount acquisition process executed by the information management device. [Figure 5] FIG. 5 is a block diagram showing the information management program. DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, exemplary embodiments will be described with reference to the drawings. Note that the same or corresponding parts in each drawing are designated by the same reference numerals, and redundant explanations will be omitted.

[0021] [Overall configuration] FIG. 1 is a block diagram showing the configuration of an information management device 1 according to this embodiment. The information management device 1 shown in FIG. 1 is a device that conducts a survey of users. More specifically, the information management device 1 transmits information on a survey form to, for example, a user terminal 2 operated by the user, and receives the information on the survey form answered at the user terminal 2. In particular, the information management device 1 conducts a first survey for the user, and then conducts a second survey for the user if conditions are met, thereby making it easier to obtain more useful information from the user.

[0022] In the following description, when the information management device 1 “transmits” various pieces of information to the user, it means that the various pieces of information transmitted from the information management device 1 are directly or indirectly received by the user terminal 2. In other words, the path by which the various pieces of information transmitted from the information management device 1 are received by the user terminal 2 is not limited. For example, the various pieces of information may be transmitted directly from the information management device 1 to the user terminal 2 via a network, or may be transmitted from the information management device 1 to another server or the like, stored therein, and then indirectly transmitted from the other server or the like to the user terminal 2. In this case, the data format of the various pieces of information may be modified by the other server or the like for convenience. Similarly, when the information management device 1 “receives” various pieces of information from the user, it means that the various pieces of information transmitted by the user terminal 2 are directly or indirectly received by the information management device 1.

[0023] A "questionnaire" is a question that is used to elicit a user's impressions or opinions regarding a product or service. A "product or service" is something that is provided to a user, and may be, for example, a product such as a beverage, food, or electrical appliance, or may be a beauty or medical service. Two examples of questionnaires are given here: a first questionnaire and a second questionnaire.

[0024] The "first questionnaire" is a questionnaire (so-called questionnaire) administered to the user before the second questionnaire. The first questionnaire includes, for example, a plurality of questions. The first questionnaire may include, as its question items, a question regarding an evaluation value for a product or service. Specifically, the first questionnaire may include, as its question items, a question for selecting a score for the product or service, for example, from 1 to 5 points. In this way, the first questionnaire does not have to be a free-text question (in other words, it may be a non-free-text question). Furthermore, in the first questionnaire, the user's answers to the questions may not be made public to other users, etc. (for example, the answers may be viewable only by an administrator).

[0025] Furthermore, the first questionnaire may include, as a question item, an item for inputting user information about the user. "User information" may be information including the user's name, attributes, contact information, etc. "User attributes" may be the user's age, gender, occupation, residence, annual income, etc.

[0026] The "second survey" is a survey conducted on users after the first survey. The second survey may be conducted on all users to whom the first survey was conducted, or on a portion of users to whom the first survey was conducted. The second survey may include, for example, an input field for word-of-mouth. "Word-of-mouth" refers to messages, etc., used by users who have purchased or experienced the target product or service to convey their impressions or opinions, etc., to other users, etc. In this way, the second survey may include free-form questions. Furthermore, the second survey may be such that users' answers to questions are made public to other users, etc.

[0027] The physical configuration of the information management device 1 will be described. The information management device 1 is physically configured as a computer C (server) equipped with a control arithmetic device, a storage device, and an input / output device, and is capable of communicating directly or indirectly with a plurality of user terminals 2 via wired or wireless connections. The control arithmetic device is configured as a controller such as a CPU (Central Processing Unit), and executes arithmetic processing and controls the storage device and the input / output device. The storage device has, for example, a main storage device and an auxiliary storage device. The main storage device is configured, for example, by RAM (Random Access Memory). The auxiliary storage device is configured, for example, by ROM (Read Only Memory). The input / output device has, for example, an input device that receives data from the outside and transmits it to the storage device, and an output device that outputs, to the outside, the results of calculations performed by the control arithmetic device and stored in the storage device.

[0028] The information management device 1, for example, executes predetermined processing by loading a program stored in ROM into RAM and executing the program loaded into RAM with a CPU. Here, the information management device 1 loads an information management program P stored in ROM into RAM and executes the information management program P loaded into RAM with a CPU, thereby executing a survey implementation process and a coupon total amount acquisition process, which will be described later. Note that the information management device 1 may have a physical configuration different from the above-described configuration.

[0029] The user terminal 2 is a terminal operated by a user or the like, and may be, for example, a smartphone, tablet, laptop, or desktop computer. The user terminal 2 is physically configured as a computer including a control and arithmetic unit, a storage device, and an input / output device, and can communicate directly or indirectly with the information management device 1 via wired or wireless connections. The control and arithmetic unit is configured as a controller such as a CPU, and performs arithmetic processing and controls the storage device and the input / output device. The storage device includes, for example, a main storage device and an auxiliary storage device. The main storage device includes, for example, RAM. The auxiliary storage device includes, for example, ROM. The input / output device includes, for example, an input device that receives data from an external device and transmits it to the storage device, and an output device that outputs the results of calculations performed by the control and arithmetic unit and stored in the storage device. The input device may accept input of response data to a questionnaire by a user. The user terminal 2, for example, loads a program stored in ROM into RAM and executes the program loaded into RAM using a CPU to perform predetermined processing.

[0030] Next, we will explain the functional configuration of the information management device 1. The information management device 1 includes a first information transmission unit 10, a first information reception unit 11, a second information transmission unit 12, a second information reception unit 13, a first output unit 14, a coupon information transmission unit 15, a coupon granting unit 16, a first response rate acquisition unit 17, a second response rate acquisition unit 18, a second output unit 19, a target first response rate acquisition unit 20, a coupon amount acquisition unit 21, and a total coupon amount acquisition unit 22.

[0031] The first information transmission unit 10 transmits first survey information to a user. "First survey information" is information related to a first survey about a product or service. The first survey information may be, for example, information on a survey form including multiple questions. When the first information transmission unit 10 transmits the first survey information to a user, the user may respond to the first survey on, for example, the user terminal 2.

[0032] The first information receiving unit 11 receives first answered questionnaire information from the user. In other words, the first answered questionnaire information is sent by the user (user terminal 2) and received by the first information receiving unit 11. "First answered questionnaire information" is information relating to the first answered questionnaire, which is the first questionnaire answered by the user. The first answered questionnaire information may be, for example, information on a questionnaire form in which all or some of the multiple questions have been answered (filled out).

[0033] The second information transmitting unit 12 transmits the second survey information to the user. More specifically, the second information transmitting unit 12 transmits the second survey information to the user who transmitted the first answered survey information to the first information receiving unit 11. "Second survey information" is information related to a second survey about a product or service. The second survey information may be, for example, information on a survey form that includes an input field for word-of-mouth. The second information transmitting unit 12 may transmit the second survey information to all users who transmitted the first answered survey information to the first information receiving unit 11, or may transmit the second survey information to some of the users who transmitted the first answered survey information to the first information receiving unit 11. When the second information transmitting unit 12 transmits the second survey information to the user, the user may respond to the second survey on, for example, the user terminal 2.

[0034] Here, the second information sending unit 12 sends second survey information to a user when a first answered survey related to first answered survey information sent by the user and received by the first information receiving unit 11 satisfies a preset sending condition. The "sending condition" is a condition for a user to whom second survey information should be sent. The sending condition may be a condition determined solely based on the first answered survey information sent by the user, or may be a condition determined based on information other than the first answered survey information in addition to the first answered survey information.

[0035] For example, the transmission condition may be that the first answered questionnaire information, in which a predetermined percentage (e.g., 50%) or more of the questions have been answered, has been transmitted to the first information receiving unit 11. The transmission condition may also be that user information, such as the user's attributes, included in the questions of the first questionnaire satisfy a predetermined condition (e.g., age 20 to under 60, company employee, resident in the Kanto region, annual income 3 million yen or more). The transmission condition may also include a condition regarding the evaluation values ​​included in the questions of the first questionnaire (e.g., the average evaluation value being within a predetermined range). The predetermined range may be, for example, a numerical range such as less than 2.0 on a 5-point scale, between 2.0 and 4.0, or 4.0 or more. In other words, the transmission condition may be that the evaluation value is lower than a predetermined level, that the evaluation value is higher than a predetermined level and lower than another predetermined level, or that the evaluation value is higher than a predetermined level.

[0036] The second information receiving unit 13 receives second answered questionnaire information from the user. In other words, the second answered questionnaire information is sent by the user (user terminal 2) and received by the second information receiving unit 13. "Second answered questionnaire information" is information about the second answered questionnaire, which is the second questionnaire answered by the user. The second answered questionnaire information may be, for example, information about a questionnaire form in which the user has answered (filled in) their impressions or opinions, etc. in the word-of-mouth input fields.

[0037] The first output unit 14 outputs user-specific answer information. "User-specific answer information" is information in which user information, first answered questionnaire information, and second answered questionnaire information are associated with one another. As described above, user information is information about a user, first answered questionnaire information is information sent by the user and received by the first information receiving unit 11, and second answered questionnaire information is information sent by the user and received by the second information receiving unit 13. For example, the first output unit 14 may send (output) the user-specific answer information to an external terminal or record (output) it on a recording medium. This makes it possible to display, save, or download the answers of each user to the questionnaire for each user using various spreadsheet software, etc.

[0038] The coupon information transmitting unit 15 transmits coupon information related to a coupon to the user. More specifically, the coupon information transmitting unit 15 transmits the coupon information to the user before the first answered survey information is received by the first information receiving unit 11. For example, the coupon information transmitting unit 15 may transmit the coupon information to the user before the first information transmitting unit 10 transmits the first survey information to the user, may transmit the coupon information to the user simultaneously with the first information transmitting unit 10 transmitting the first survey information to the user, or may transmit the coupon information to the user after the first information transmitting unit 10 transmits the first survey information to the user but before the first information receiving unit 11 receives the first answered survey information.

[0039] A "coupon" may be, for example, a right having monetary value. That is, a coupon may be a right to receive a discount on a product or to have a product transferred in exchange for the coupon. Such a product (target product) may be a beverage or food such as coffee, tea, or chocolate. Alternatively, a coupon may be a right to receive a discount on a service or to have a service performed in exchange for the coupon. The amount of discount on a product or service in exchange for a coupon can be set arbitrarily, and may be, for example, 100 yen or 200 yen. A coupon may be a real object made of, for example, paper, or may be electronic information.

[0040] "Coupon information" is information for making a user aware of a coupon. For example, the coupon information may be information for making a user aware that the user may be granted a coupon. The coupon information may also be information for making a user aware of the conditions for the user to be granted a coupon.

[0041] The coupon granting unit 16 grants a coupon to a user. For example, if the coupon is a real object made of paper or the like, the coupon granting unit 16 may grant the coupon to the user by outputting an instruction to deliver the coupon to the user. Also, for example, if the coupon is electronic information, the coupon granting unit 16 may grant the coupon to the user by sending the user a link or a two-dimensional code image or the like for accessing the coupon.

[0042] The coupon granting unit 16 may grant a coupon to a user on at least the condition that first answered survey information sent by the user has been received by the first information receiving unit 11. Specifically, the coupon granting unit 16 may grant a coupon to a user on the only condition that the first answered survey information sent by the user has been received by the first information receiving unit 11. In other words, the coupon granting unit 16 may grant a coupon to a user when the first answered survey information sent by the user has been received by the first information receiving unit 11.

[0043] Alternatively, the coupon granting unit 16 may grant a coupon to a user when first answered survey information sent by the user is received by the first information receiving unit 11 and second answered survey information sent by the user is received by the second information receiving unit 13. Alternatively, the coupon granting unit 16 may grant a coupon to a user when first answered survey information sent by the user is received by the first information receiving unit 11 and the user wins a lottery. Alternatively, the coupon granting unit 16 may grant a coupon to a user when first answered survey information sent by the user is received by the first information receiving unit 11 and the answer content in the first answered survey satisfies a predetermined condition.

[0044] The first response rate acquisition unit 17 acquires a first response rate. The "first response rate" is the response rate to the first questionnaire. Specifically, the first response rate is a response rate calculated as the proportion of users who received the first answered questionnaire information by the first information receiving unit 11 among the users to whom the first questionnaire information was transmitted by the first information transmitting unit 10. Note that the first response rate acquisition unit 17 may acquire the first response rate by calculating the proportion of users who received the first answered questionnaire information by the first information receiving unit 11 among the users to whom the first questionnaire information was transmitted by the first information transmitting unit 10. Alternatively, the first response rate acquisition unit 17 may acquire a first response rate calculated, for example, by an external terminal or the like.

[0045] The first response rate may be calculated for each content of a coupon given to a user. In other words, the first response rate may be calculated for users who have been given a coupon with a specific content. In this case, the first response rate acquisition unit 17 may acquire the first response rate calculated for each content of a coupon as the proportion of users who have received the first answered survey information by the first information receiving unit 11, among users to whom the first survey information was sent by the first information transmission unit 10. The first response rate calculated for each content of a coupon may be referred to as a first response rate by coupon. The first response rate by coupon may be calculated by integrating coupons with similar content (having a predetermined commonality).

[0046] The second response rate acquisition unit 18 acquires a second response rate. The "second response rate" is the response rate to the second questionnaire. Here, the second response rate may be the response rate to the second questionnaire, whose population is the subjects of the first questionnaire. Specifically, the second response rate may be a response rate calculated as the proportion of users who received the second completed questionnaire information by the second information receiving unit 13 among users to whom the first questionnaire information was transmitted by the first information transmission unit 10. Alternatively, the second response rate may be a response rate to the second questionnaire, whose population is the subjects of the second questionnaire. Specifically, the second response rate may be a response rate calculated as the proportion of users who received the second completed questionnaire information by the second information receiving unit 13 among users to whom the second questionnaire information was transmitted by the second information transmission unit 12. The second response rate acquisition unit 18 may acquire the second response rate by calculating the proportion of users who received the second answered survey information by the second information receiving unit 13, among users to whom the first survey information was sent by the first information sending unit 10 or users to whom the second survey information was sent by the second information sending unit 12. Alternatively, the second response rate acquisition unit 18 may acquire the second response rate calculated, for example, by an external terminal.

[0047] The second response rate may be calculated for each coupon content provided to a user. That is, the second response rate may be calculated for users who have been provided with coupons of specific content. In this case, the second response rate acquisition unit 18 may acquire the second response rate calculated for each coupon content as the proportion of users who have received the second answered survey information by the second information receiving unit 13, among users to whom the first survey information was sent by the first information sending unit 10 or the second survey information was sent by the second information sending unit 12. The second response rate calculated for each coupon content may be referred to as a coupon-specific second response rate. The coupon-specific second response rate may be calculated by integrating coupons with similar content (having a predetermined commonality).

[0048] The second output unit 19 outputs coupon-specific response rate information. "Coupon-specific response rate information" is information in which the coupon content, the first response rate, and the second response rate are associated with each other. As described above, the first response rate is the response rate calculated in accordance with the coupon content, and the second response rate is the response rate calculated in accordance with the coupon content. For example, the second output unit 19 may transmit (output) the coupon-specific response rate information to an external terminal or record (output) it on a recording medium. This makes it possible to display, save, or download the survey response rate calculated for each coupon content using various spreadsheet software, etc.

[0049] 2 is a diagram showing an example of variables used in the total coupon amount acquisition process. As shown in FIGS. 1 and 2, the target first response rate acquisition unit 20 acquires the target first response rate. The "target first response rate" is the target value of the first response rate described above. In other words, the target first response rate is the target value of the first response rate calculated as the proportion of users who have received the first answered survey information by the first information receiving unit 11 among users to whom the first survey information was sent by the first information sending unit 10.

[0050] The target first response rate is calculated based on the number of target users, the expected second response rate, and the target second response number. Here, the number of target users is the number of users to whom the first survey information was transmitted by the first information transmission unit 10. The expected second response rate is an expected value of the second response rate calculated as the proportion of users who received the second completed survey information by the second information receiving unit 13 among the users to whom the first survey information was transmitted by the first information transmission unit 10 or the users to whom the second survey information was transmitted by the second information transmission unit 12. This expected second response rate may be an arbitrary predicted value or a value calculated from past data. The target second response number is a target value for the number of users who will receive the second completed survey information by the second information receiving unit 13. This target second response number may be a desired value or a value calculated using a predetermined calculation formula. Note that the "user to whom the first survey information has been sent by the first information sending unit 10" may be a user to whom the first survey information has already been sent by the first information sending unit 10, or a user who is assumed to have received the first survey information by the first information sending unit 10, or a user to whom the first survey information is to be sent (to whom the information is to be sent) by the first information sending unit 10. Similarly, the "user to whom the second survey information has been sent by the second information sending unit 12" may be a user to whom the second survey information has already been sent by the second information sending unit 12, or a user who is assumed to have received the second survey information by the second information sending unit 12, or a user to whom the second survey information is to be sent (to whom the information is to be sent) by the second information sending unit 12.

[0051] As an example, the target first response rate acquisition unit 20 may calculate the target first response rate based on the formula (Formula 1): Target First Response Rate = Target Number of Second Responses / (Number of Target Users × Expected Second Response Rate). In FIG. 2, the number of target users is set to 5,000, the expected second response rate is set to 10%, and the target number of second responses is set to 50, so the target first response rate is calculated to be 10%. Note that the target first response rate acquisition unit 20 may calculate the target first response rate based on a formula obtained by modifying the above Formula 1. For example, the above Formula 1 may be multiplied by a coefficient or a new term may be added for correction. Alternatively, the target first response rate acquisition unit 20 may acquire the target first response rate by calculating the target first response rate based on the number of target users, the expected second response rate, and the target number of second responses. Alternatively, the target first response rate acquisition unit 20 may acquire the target first response rate calculated, for example, by an external terminal or the like.

[0052] The coupon amount acquisition unit 21 acquires the coupon amount. The "coupon amount" is the monetary value (unit price) of one coupon granted to a user by the coupon granting unit 16. The coupon amount is calculated based on the expected second response cost and the above-mentioned expected second response rate. The expected second response cost is the expected unit price required for the second information receiving unit 13 to receive the second completed survey information. This expected second response cost may be an arbitrary predicted amount, a desired amount, or an amount calculated from past data. The expected second response cost may be set for each industry, such as the food industry, the medical industry, or the beauty industry.

[0053] As an example, the coupon amount acquisition unit 21 may calculate the coupon amount based on the formula (Formula 2) where: Coupon amount = Expected second response rate × Expected second response cost. In FIG. 2, the expected second response cost is set to 1,000 yen, and the expected second response rate is set to 10% as described above, so the coupon amount is calculated to be 100 yen. The coupon amount acquisition unit 21 may calculate the coupon amount based on a formula obtained by modifying the above formula 2. For example, the above formula 2 may be multiplied by a coefficient or a new term may be added for correction. The coupon amount acquisition unit 21 may also acquire the coupon amount by calculating the coupon amount based on the expected second response cost and the expected second response rate. Alternatively, the coupon amount acquisition unit 21 may acquire the coupon amount calculated, for example, by an external terminal or the like.

[0054] The total coupon amount acquisition unit 22 acquires the total coupon amount. The "total coupon amount" is the total value of the coupon amounts of the coupons granted to users by the coupon granting unit 16. The total coupon amount is calculated based on the number of target users, the target first response rate, and the coupon amount.

[0055] As an example, the total coupon amount obtaining unit 22 may calculate the total coupon amount based on the formula (Formula 3): Total coupon amount = Number of target users × Target first response rate × Coupon amount. In FIG. 2, the number of target users is 5,000 as described above, the target first response rate is calculated to be 10% as described above, and the coupon amount is calculated to be 100 yen as described above, so the total coupon amount is calculated to be 50,000 yen. The total coupon amount obtaining unit 22 may calculate the total coupon amount based on a formula obtained by modifying the above Formula 3. For example, the above Formula 3 may be multiplied by a coefficient or a new term for correction may be added. The total coupon amount obtaining unit 22 may also obtain the total coupon amount by calculating the total coupon amount based on the number of target users, the target first response rate, and the coupon amount. Alternatively, the total coupon amount obtaining unit 22 may obtain the total coupon amount calculated, for example, by an external terminal or the like.

[0056] [Survey execution process] Next, a description will be given of the survey implementation process executed by the information management device 1. Fig. 3 is a flowchart showing the survey implementation process executed by the information management device 1. As shown in Fig. 3, the survey implementation process is a process of conducting a two-stage survey on users in order to collect more useful information.

[0057] In step S10, the first information transmission unit 10 of the information management device 1 transmits first survey information, which is information regarding a first survey about a product or service, to the user. When the first information transmission unit 10 transmits the first survey information to the user, the user may respond to the first survey, for example, on the user terminal 2. Thereafter, the survey implementation process proceeds to step S12.

[0058] In step S12, the coupon information transmitting unit 15 of the information management device 1 transmits coupon information, which is information for making the user aware of a coupon, to the user before the first answered survey information is received by the first information receiving unit 11. Here, as an example, the coupon information is information for making the user aware of the conditions for the user to be granted a coupon. Furthermore, the coupon information transmitting unit 15 transmits the coupon information to the user after the first information transmitting unit 10 transmits the first survey information to the user. Thereafter, the survey implementation process proceeds to step S14.

[0059] In step S14, if the user has sent the first answered questionnaire information, the first information receiving unit 11 of the information management device 1 receives the first answered questionnaire information from the user (step S14: YES). In this case, the survey implementation process proceeds to step S16. On the other hand, if the user has not sent the first answered questionnaire information, the first information receiving unit 11 of the information management device 1 does not receive the first answered questionnaire information from the user (step S14: NO). In this case, the survey implementation process ends.

[0060] In step S16, the coupon granting unit 16 of the information management device 1 grants a coupon to the user. Note that although the coupon granting unit 16 grants the coupon to the user at this timing here, the coupon granting unit 16 may grant the coupon to the user at a different timing. Thereafter, the survey implementation process proceeds to step S18.

[0061] In step S18, the second information transmitting unit 12 of the information management device 1 determines whether the first answered questionnaire related to the first answered questionnaire information transmitted by the user and received by the first information receiving unit 11 satisfies the preset transmission conditions. If it is determined that the first answered questionnaire satisfies the transmission conditions (step S18: YES), the survey implementation process proceeds to step S20. On the other hand, if it is determined that the first answered questionnaire does not satisfy the transmission conditions (step S18: NO), the survey implementation process ends.

[0062] In step S20, the second information transmission unit 12 of the information management device 1 transmits second survey information, which is information regarding a second survey about a product or service, to the user. When the second information transmission unit 12 transmits the second survey information to the user, the user may respond to the second survey, for example, on the user terminal 2. Thereafter, the survey implementation process proceeds to step S22.

[0063] In step S22, if the user has sent second answered questionnaire information, the second information receiving unit 13 of the information management device 1 receives the second answered questionnaire information from the user (step S22: YES). In this case, the survey implementation process proceeds to step S24. On the other hand, if the user has not sent second answered questionnaire information, the second information receiving unit 13 of the information management device 1 does not receive the second answered questionnaire information from the user (step S22: NO). In this case, the survey implementation process ends.

[0064] In step S24, the first output unit 14 of the information management device 1 outputs user-specific answer information, which is information in which the user information, the first answered survey information, and the second answered survey information are associated with each other. The first output unit 14 may transmit (output) the user-specific answer information to an external terminal or record (output) it on a recording medium. Thereafter, the survey implementation process proceeds to step S26.

[0065] In step S26, the first response rate acquisition unit 17 of the information management device 1 acquires a first response rate, which is a response rate calculated as the proportion of users who received the first answered survey information by the first information receiving unit 11 among users to whom the first survey information was sent by the first information sending unit 10. Here, the first response rate acquisition unit 17 acquires the first response rate calculated for each coupon to be granted to the user. Thereafter, the survey implementation process proceeds to step S28.

[0066] In step S28, the second response rate acquisition unit 18 of the information management device 1 acquires a second response rate, which is a response rate calculated as the proportion of users who received the second answered survey information by the second information receiving unit 13, among users to whom the first survey information was sent by the first information sending unit 10 or users to whom the second survey information was sent by the second information sending unit 12. Here, the second response rate acquisition unit 18 acquires the second response rate calculated for each content of the coupon to be granted to the user. Thereafter, the survey implementation process proceeds to step S30.

[0067] In step S30, the second output unit 19 of the information management device 1 outputs coupon-specific response rate information, which is information in which the coupon content, the first response rate, and the second response rate are associated with each other. The second output unit 19 may transmit (output) the coupon-specific response rate information to an external terminal, or may record (output) it on a recording medium. This completes the survey implementation process.

[0068] [Coupon total amount acquisition process] Next, a description will be given of the total coupon amount acquisition process executed by the information management device 1. Fig. 4 is a flowchart showing the total coupon amount acquisition process executed by the information management device 1. As shown in Fig. 4, the total coupon amount acquisition process is a process for calculating an appropriate amount of coupons to be given to a user.

[0069] In step S40, the coupon amount acquisition unit 21 of the information management device 1 acquires an estimated second response unit price, which is an estimated price required to receive the second answered survey information by the second information receiving unit 13. After that, the total coupon amount acquisition process proceeds to step S42.

[0070] In step S42, the coupon amount acquisition unit 21 of the information management device 1 acquires an expected second response rate, which is an expected value of the second response rate calculated as the proportion of users who will receive the second answered survey information by the second information receiving unit 13, among users to whom the first survey information was sent by the first information sending unit 10, or users to whom the second survey information was sent by the second information sending unit 12. The coupon amount acquisition unit 21 may acquire from the target first response rate acquisition unit 20 the expected second response rate previously acquired by the target first response rate acquisition unit 20. Thereafter, the total coupon amount acquisition process proceeds to step S44.

[0071] In step S44, the coupon amount obtaining unit 21 of the information management device 1 obtains the coupon amount, which is the monetary value (unit price) of one coupon to be provided to the user by the coupon providing unit 16. The coupon amount obtaining unit 21 obtains the coupon amount calculated based on, for example, the expected second response unit price and the expected second response rate. Thereafter, the total coupon amount obtaining process proceeds to step S46.

[0072] In step S46, the total coupon amount acquisition unit 22 of the information management device 1 acquires the number of target users, which is the number of users to whom the first survey information was sent by the first information transmission unit 10. The total coupon amount acquisition unit 22 may acquire the number of target users previously acquired by the target first response rate acquisition unit 20, from the target first response rate acquisition unit 20. Thereafter, the total coupon amount acquisition process proceeds to step S48.

[0073] In step S48, the total coupon amount acquisition unit 22 of the information management device 1 acquires a target first response rate, which is a target value of the first response rate calculated as the proportion of users who have received the first answered survey information by the first information receiving unit 11, among users to whom the first survey information was sent by the first information transmitting unit 10. The total coupon amount acquisition unit 22 may acquire the target first response rate acquired by the target first response rate acquisition unit 20 from the target first response rate acquisition unit 20. Thereafter, the total coupon amount acquisition process proceeds to step S50.

[0074] In step S50, the total coupon amount obtaining unit 22 of the information management device 1 obtains the total coupon amount calculated based on the number of target users, the target first response rate, and the coupon amount. This completes the total coupon amount obtaining process.

[0075] [Information Management Program] The following describes an information management program P for causing a computer C to function as the information management device 1. Fig. 5 is a block diagram showing the information management program P. The information management program P includes a main module MM, a first information transmission module M10, a first information reception module M11, a second information transmission module M12, a second information reception module M13, a first output module M14, a coupon information transmission module M15, a coupon granting module M16, a first response rate acquisition module M17, a second response rate acquisition module M18, a second output module M19, a target first response rate acquisition module M20, a coupon amount acquisition module M21, and a total coupon amount acquisition module M22.

[0076] The main module MM is the part that controls the computer C in an overall manner.

Furthermore, the information management program P may not include all or some of the modules mentioned above other than the main module MM, the first information transmitting module M10, the first information receiving module M11, the second information transmitting module M12, and the second information receiving module M13.

[0077] [Action and effect] As described above, the information management device 1 includes a first information sending unit 10 that sends first survey information regarding a first survey about a product or service to a user, a first information receiving unit 11 that receives first answered survey information regarding a first answered survey, which is the first survey answered by the user, from the user, a second information sending unit 12 that sends second survey information regarding a second survey about a product or service to the user that sent the first answered survey information to the first information receiving unit 11, and a second information receiving unit 13 that receives second answered survey information regarding a second answered survey, which is the second survey answered by the user, from the user.

[0078] The information management program P causes the computer C to function as a first information sending unit 10 that sends first survey information regarding a first survey about a product or service to a user, a first information receiving unit 11 that receives first answered survey information from a user regarding a first answered survey, which is a first survey answered by the user, a second information sending unit 12 that sends second survey information regarding a second survey about a product or service to the user that sent the first answered survey information to the first information receiving unit 11, and a second information receiving unit 13 that receives second answered survey information from the user regarding a second answered survey, which is a second survey answered by the user.

[0079] According to at least one of the information management device 1 and the information management program P, by sending a second questionnaire to users who have answered a first questionnaire about a product or service, it is possible to obtain further information that the users have not answered in the first questionnaire. This makes it possible to obtain more useful information from the respondents to the questionnaire.

[0080] In the information management device 1, the second information transmitting unit 12 transmits the second questionnaire information to the user when the first answered questionnaire related to the first answered questionnaire information received by the first information receiving unit 11 satisfies a preset transmission condition. This makes it possible to further obtain information that was not answered in the first questionnaire from users who have desired characteristics among the users who answered the first questionnaire.

[0081] In the information management device 1, the first questionnaire includes items related to the evaluation value of the product or service, and the transmission conditions include conditions related to the evaluation value. This makes it possible to select users to whom the second questionnaire is to be sent based on the evaluation results clearly indicated by the users as evaluation values.

[0082] The information management device 1 includes a first output unit 14 that outputs user-specific answer information that correlates user information about a user, first answered questionnaire information sent by the user and received by the first information receiving unit 11, and second answered questionnaire information sent by the user and received by the second information receiving unit 13. This makes it easier to understand trends in the answers to questionnaires for each user.

[0083] The information management device 1 includes a coupon information sending unit 15 that sends coupon information related to a coupon to a user before the first answered questionnaire information is received by the first information receiving unit 11, and a coupon granting unit 16 that grants a coupon to the user on at least the condition that the first answered questionnaire information sent by the user has been received by the first information receiving unit 11. This allows the user to be made aware of the content of the coupon or the conditions for granting the coupon before granting the coupon to the user.

[0084] The information management device 1 includes a first response rate acquisition unit 17 that acquires a first response rate calculated as the proportion of users who received first answered survey information by the first information receiving unit 11 among users to whom first survey information was transmitted by the first information transmitting unit 10, and a second response rate acquisition unit 18 that acquires a second response rate calculated as the proportion of users who received second answered survey information by the second information receiving unit 13 among users to whom the first survey information was transmitted by the first information transmitting unit 10 or users to whom the second survey information was transmitted by the second information transmitting unit 12. This makes it possible to grasp the proportion of users who will respond to the survey.

[0085] The information management device 1 includes a coupon information sending unit 15 that sends coupon information related to a coupon to a user before the first answered questionnaire information is received by the first information receiving unit 11, a coupon granting unit 16 that grants a coupon to the user on at least the condition that the first answered questionnaire information sent by the user has been received by the first information receiving unit 11, and a first response rate calculated for each coupon content as the proportion of users who received the first answered questionnaire information by the first information receiving unit 11 among users to whom the first questionnaire information was sent by the first information sending unit 10. The coupon response information acquisition unit 17 includes a first response rate acquisition unit 17 that acquires a second response rate calculated for each coupon content as the proportion of users who received the second answered survey information by the second information receiving unit 13 among users to whom the first survey information was sent by the first information sending unit 10 or the second survey information was sent by the second information sending unit 12, and a second output unit 19 that outputs coupon-specific response rate information in which the coupon content, the first response rate calculated corresponding to the coupon content, and the second response rate calculated corresponding to the coupon content are mutually associated. This makes it possible to grasp the relationship between the coupon content and the proportion of users who respond to the survey, thereby obtaining data that is useful for examining cost-effectiveness.

[0086] The information management device 1 includes a target first response rate acquisition unit 20 that acquires a target first response rate, which is calculated as the proportion of users who have received the first answered survey information by the first information receiving unit 11 among users who have received the first survey information by the first information transmitting unit 10, and which is calculated based on the number of target users, an expected second response rate, and a target second number of responses, where the number of target users is the number of users to whom the first survey information is transmitted by the first information transmitting unit 10, the expected second response rate is the predicted value of the second response rate calculated as the proportion of users who have received the second answered survey information by the second information receiving unit 13 among users to whom the first survey information is transmitted by the first information transmitting unit 10 or the second survey information is transmitted by the second information transmitting unit 12, and the target second number of responses is a target value for the number of users who will receive the second answered survey information by the second information receiving unit 13. This makes it possible to grasp the target value of the user response rate for the first survey, and therefore it is possible to acquire data that is useful for considering measures to achieve a required level of response rate.

[0087] The information management device 1 includes a coupon information sending unit 15 that sends coupon information related to a coupon to a user before the first answered survey information is received by the first information receiving unit 11, a coupon granting unit 16 that grants a coupon to the user on at least the condition that the first answered survey information sent by the user has been received by the first information receiving unit 11, and a coupon amount obtaining unit 21 that obtains an expected second response cost, which is the monetary value of one coupon granted to the user by the coupon granting unit 16 and is an expected value of the unit cost required to receive the second answered survey information by the second information receiving unit 13, and an expected second response rate. This makes it possible to estimate an appropriate coupon amount.

[0088] The information management device 1 includes a total coupon amount acquisition unit 22 that acquires the total coupon amount, which is the total value of the coupon amounts of the coupons granted to users by the coupon granting unit 16, calculated based on the number of target users, the target first response rate, and the coupon amount. This makes it possible to estimate the budget required for issuing coupons.
