[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0017] FIG. 1 is an overall view of a store system 1 according to this embodiment. The store system 1 is a system that manages the work of employees at a store that provides food and drink products, such as a restaurant. The store system 1 may manage one store or multiple stores.

[0018] The store system 1 comprises a work manager device 10, an order terminal device 20, an accounting device 30, and an administrator device 40. The work manager device 10, order terminal device 20, accounting device 30, and administrator device 40 are connected via a network N such as a wireless LAN (Local Area Network). The work manager device 10 is configured, for example, from a stationary general-purpose computer or a cloud-based server, and manages the work of employees at stores such as restaurants.

[0019] The order terminal device 20 is a smart device such as a handheld terminal, smartphone, or tablet terminal. The order terminal device 20 is carried by a user such as a waiter and is used to input orders from customers. The input information is sent to the accounting device 30. Although the example shown in FIG. 1 shows one order terminal device 20, there may be multiple order terminal devices 20. The accounting device 30 performs accounting processing for the ordered items. The manager device 40 is an information processing device used by a manager or the like of the store system 1. In this embodiment, the manager device 40 requests work shifts from the work manager device 10 in response to operation by the manager, and upon receiving the work shifts, displays them on the display unit 41.

[0020] The work manager device 10 comprises a control unit 11, a storage unit 12, and a communication unit 13. The control unit 11 includes a processor such as a CPU (Central Processing Unit) and memories for the processor to execute processes such as ROM (Read Only Memory) and RAM (Random Access Memory), and executes various processes. The control unit 11 executes various programs stored in the storage unit 12, ROM, etc. The control unit 11 of this embodiment manages work, etc. by executing programs stored in the storage unit 12.

[0021] The control unit 11 of the work manager device 10 includes, as functional units, a predicted sales amount acquisition unit 111, a work shift creation unit 112, a predicted man-hour sales amount calculation unit 113, an actual man-hour sales amount calculation unit 114, a difference calculation unit 115, and a display processing unit 116. The functions of the predicted sales amount acquisition unit 111, the work shift creation unit 112, the predicted man-hour sales amount calculation unit 113, the actual man-hour sales amount calculation unit 114, the difference calculation unit 115, and the display processing unit 116 are realized by the processor reading out a program stored in the memory unit 12 or the like and executing this program. In other words, the processes described as being executed by each of the above functional units are processes executed by the control unit 11.

[0022] The predicted sales acquisition unit 111 acquires predicted sales for each unit time of each day. Here, a unit time is a predetermined time, such as one hour or 30 minutes, which is a unit shorter than one day. In restaurants and the like, sales fluctuate depending on the day of the week and the time of day, so predicted sales for each unit time are acquired in this way. The work shift creation unit 112 creates work shifts based on the predicted sales. A work shift includes the number of employees who should be working at each date and time, and the identification information of the employees who will be working. Here, the employee identification information is the employee's name, etc. Here, employees include part-time employees, casual employees, full-time employees, etc.

[0023] The predicted man-hour sales calculation unit 113 calculates predicted man-hour sales. The actual man-hour sales calculation unit 114 calculates actual man-hour sales. The predicted man-hour sales is the sales per unit time and per employee determined by the predicted sales and the number of employees indicated in the work shift. The actual man-hour sales is the actual sales per unit time and per employee determined by the actual sales (hereinafter referred to as actual sales) and the number of employees who actually worked (hereinafter referred to as actual number of employees). In restaurants and the like, labor costs fluctuate in addition to sales. Therefore, man-hour sales is calculated as an indicator of profit. The difference calculation unit 115 calculates the man-hour sales difference, which is the difference between the actual man-hour sales and the predicted man-hour sales. In this embodiment, the difference calculation unit 115 obtains the value obtained by subtracting the predicted man-hour sales from the actual man-hour sales as the man-hour sales difference.

[0024] The display processing unit 116 displays the man-hour sales difference on the display unit 41 of the manager device 40. Specifically, the display processing unit 116 transmits the man-hour sales difference to the manager device 40. Then, the manager device 40 receives the man-hour sales difference and displays it on the display unit 41. Note that detailed processing in each functional unit of the work manager device 10 will be described later with reference to FIG. 2 etc.

[0025] FIG. 2 is a flowchart showing the first work management process by the work manager device 10. Here, one week is the processing target. However, the processing target period is not limited to this and may be, for example, one day or one month. In the first work management process, the predicted sales amount acquisition unit 111 of the work manager device 10 acquires the predicted sales amount for each unit time during the processing target period (one week) (Step S100). Here, the unit time is one hour. The predicted sales amount acquisition unit 111 acquires the predicted sales amount for each hour for each day during the processing target period, such as the predicted sales amount at 4:00 PM and the predicted sales amount at 5:00 PM. The predicted sales amount for each unit time is assumed to be input by the manager via the manager device 40, and the predicted sales amount acquisition unit 111 acquires the predicted sales amount from the manager device 40 via the communication unit 13.

[0026] As another example, past sales may be stored in the memory unit 12 of the work manager device 10, and the predicted sales amount obtaining unit 111 may determine the predicted sales amount from the past sales amount. For example, the predicted sales amount obtaining unit 111 may determine the sales amount for each hour of the day one week before the target day to be processed as the predicted sales amount for each hour of the target day to be processed.

[0027] Next, the work shift creation unit 112 creates work shifts for the period to be processed (step S102). Specifically, first, the number of employees to be employed (hereinafter referred to as the planned number of employees) is determined based on the predicted sales amount for each unit time. In this way, the work shift creation unit 112 determines the planned number of employees. In other words, the work shift creation unit 112 is an example of an employee number determination unit that determines the planned number of employees based on the predicted sales amount.

[0028] Next, the work shift creation unit 112 assigns employees scheduled to work to each time slot according to the determined number of employees scheduled to work. Note that the employee assignment is performed by the manager operating the manager device 40 in accordance with the employee's wishes. As another example, each employee may input the time slot they wish to work on an employee device such as a mobile terminal (not shown) carried by the employee, and employees may be assigned according to this input. With the number of employees determined and the employee assignment completed, the work shift is complete.

[0029] As another example, a sales standard range, which is a standard range of predicted man-hour sales, may be set in advance. In this case, the work shift creation unit 112 determines the planned number of employees for each unit time so that the predicted man-hour sales fall within the sales standard range. This automatically allocates the number of employees to achieve the desired predicted man-hour sales.

[0030] Next, the predicted man-hour sales calculation unit 113 calculates the predicted man-hour sales for each unit time based on the planned number of employees for each unit time indicated in the work shift and the predicted sales for each corresponding unit time (step S104). For example, if the predicted sales for a unit time is x and the planned number of employees for a unit time is y, then x / y is the predicted man-hour sales for the unit time. The predicted sales, planned number of employees, and predicted man-hour sales obtained in the first work management process are stored in the memory unit 12 together with the work shift.

[0031] FIG. 3(a) shows a bar graph of predicted sales. The horizontal axis represents time, and the vertical axis represents predicted sales. FIG. 3(b) shows a bar graph of the planned number of employees. The horizontal axis represents time, and the vertical axis represents the planned number of employees. FIG. 3(c) shows a bar graph of predicted sales per man-hour. The horizontal axis represents time, and the vertical axis represents predicted sales per man-hour. Based on the predicted sales shown in FIG. 3(a) and the planned number of employees shown in FIG. 3(b), the predicted sales per man-hour shown in FIG. 3(c) is calculated.

[0032] Next, the second work management process by the work manager device 10 will be described. FIG. 4 is a flowchart showing the second work management process. The second work management process is executed after the period to be processed in the first work management process has elapsed, with a period within the elapsed period as the processing target. This process is executed, for example, when an execution request is received from the manager device 40. In this case, the processing target is specified together with the execution request.

[0033] First, the actual sales amount calculation unit 114 processes a predetermined period that has passed, and acquires the actual sales amount per unit time within the predetermined period from the accounting device 30 via the communication unit 13 (S200). Here, the predetermined period may be the same as or different from the period that is the processing target in the first work management process.

[0034] Next, the actual manned sales calculation unit 114 acquires the actual number of employees per unit time during the period to be processed (S202). Here, the actual number of employees is the number of employees who actually worked. The actual number of employees is assumed to be input, for example, by the administrator operating the administrator device 40. Then, the actual manned sales calculation unit 114 acquires the actual number of employees from the administrator device 40 via the communication unit 13. Next, the actual manned sales calculation unit 114 calculates the actual manned sales per unit time during the period to be processed based on the actual sales amount and the actual number of employees (S204).

[0035] FIG. 5(a) shows a bar graph of actual sales. The horizontal axis indicates time, and the vertical axis indicates actual sales. FIG. 5(b) shows a bar graph of the actual number of employees. The horizontal axis indicates time, and the vertical axis indicates the actual number of employees. FIG. 5(c) shows a bar graph of actual sales during working hours. The horizontal axis indicates time, and the vertical axis indicates actual sales during working hours. Based on the actual sales shown in FIG. 5(a) and the actual number of employees shown in FIG. 5(b), the actual sales during working hours shown in FIG. 5(c) are calculated.

[0036] Actual sales may differ from forecasted sales. The actual number of employees may also differ from the planned number of employees due to, for example, sudden absences by employees or overtime work due to busy schedules. As a result, actual sales per person-hour may also differ from forecasted sales per person-hour.

[0037] Next, the difference calculation unit 115 calculates a man-hour sales difference, which is the difference between the actual man-hour sales and the predicted man-hour sales (S206). Next, the display processing unit 116 displays the man-hour sales difference on the display unit 41 of the administrator device 40 (S208). Specifically, the display processing unit 116 transmits the man-hour sales difference to the administrator device 40 via the communication unit 13.

[0038] 6 is a diagram showing a display screen 400 of the man-hour sales difference displayed on the display unit 41 of the administrator device 40. A bar graph showing the man-hour sales difference is displayed on the display screen 400. The horizontal axis of the man-hour sales difference graph shows time, and the vertical axis shows the man-hour sales difference.

[0039] Furthermore, the display processing unit 116 displays bars for time periods in which the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales, which is the difference between the predicted man-hour sales and the actual man-hour sales, is equal to or greater than the warning threshold, in a color different from the bars for other time periods. For example, as shown in FIG. 6 , assume that the actual man-hour sales are smaller than the predicted man-hour sales and the difference between the predicted man-hour sales and the actual man-hour sales is equal to or greater than the warning threshold between 9:00 PM and 10:00 PM. Furthermore, assume that the actual man-hour sales are greater than the predicted man-hour sales in other time periods (4:00 PM to 8:00 PM). In this case, 9:00 PM and 10:00 PM are classified as a first time period, and the bars corresponding to these time periods are displayed with diagonal hatching. Furthermore, time periods other than the first time period, i.e., 4:00 PM to 8:00 PM, are classified as a second time period, and the bars corresponding to these time periods are displayed in white without hatching. The warning threshold is a preset value. In this embodiment, the warning threshold is a negative value, but the warning threshold can be set arbitrarily. For example, the warning threshold may be zero or a positive value.

[0040] In this embodiment, the first time zone and the second time zone are displayed with or without hatching, but the display manner is not limited to the embodiment as long as the two time zones are displayed in different display modes so that they can be distinguished. As another example, the bars for the two time zones may be displayed in different colors. As another example, the frame of the bar for the first time zone may be displayed with a thicker line than the frame of the bar for the second time zone.

[0041] In this way, by displaying each time period in a different manner, the manager can understand that there were too many employees at 9 p.m. and 10 p.m., that is, that the work being done was not commensurate with sales.

[0042] In restaurants and other establishments, during busy hours, unscheduled employees may be working. On the other hand, even when the business is not busy, there may be unnecessary work performed by more employees than the number expected for the work shift. However, in the past, it was difficult to identify such unnecessary work. In contrast, the work manager device 10 of this embodiment can automatically extract time periods during which unnecessary work may have been performed and display them in a manner that makes them distinguishable from other time periods. Therefore, the work manager device 10 of this embodiment allows the manager to easily check whether or not there is unnecessary work. Ultimately, labor costs can be reduced.

[0043] The above embodiment is one example for implementing the present invention, and various other embodiments are possible. For example, various modifications and changes are possible within the scope of the gist of the present invention described in the claims, such as applying one modified example to another modified example. For example, the present invention may be realized as a work management system in which multiple functional units constituting the work manager device 10 are distributed across different devices. Furthermore, some of the components of the above embodiment may be omitted, and the order of processing may be changed or omitted.

[0044] As a first variant example, the predicted man-hour sales amount calculation process (step S104) in the first work management process, which was explained with reference to Figure 2, only needs to be executed before the man-hour sales amount difference calculation process (S206) in the second work management process, and the timing of execution is not limited to the embodiment.

[0045] As a second variation, the period to be processed in the second work management process is not limited to that described in the embodiment. Furthermore, the timing of execution of the second work management process is not limited to that described in the embodiment. For example, the second work management process may be executed after the end of business hours for a week that is the subject of processing in the first work management process, with the week as the processing subject. As another example, the second work management process may be executed after the end of business hours for a week, with the specified day as the processing subject, if the administrator designates a specific day within the week.

[0046] As a third variant, the first time period may be limited to time periods in which actual man-hour sales are smaller than predicted man-hour sales, the difference is greater than the warning threshold, and the actual number of employees is greater than the planned number of employees.

[0047] When the actual man-hour sales are smaller than the predicted man-hour sales and the difference is equal to or greater than the warning threshold, it is assumed that the actual number of employees is too high compared to the actual sales, or that the actual sales are lower than the predicted sales. By distinguishing between these cases, the manager can easily understand that more people than were planned to work in the work shift were actually working.

[0048] As a fourth modification, the display processing unit 116 may classify, among the time periods when the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold, the time periods when the actual number of employees is equal to or less than the planned number of employees as the third time period. Then, the display processing unit 116 causes the display unit 41 to display the first time period, the second time period, and the third time period so that they can be distinguished from one another.

[0049] For example, as shown in Figures 3(b) and 5(b), at 8:00 PM, the actual number of employees was greater than the planned number of employees, resulting in lower actual sales than the predicted sales per man-hour. On the other hand, at 9:00 PM, although the actual number of employees was equal to the planned number of employees, the actual sales were less than the predicted sales, resulting in lower actual sales than the predicted sales. Therefore, the display processing unit 116 classifies 9:00 PM as a third time slot.

[0050] FIG. 7 is a diagram showing an example of a display screen 410 according to this modification. As shown in FIG. 7, the bars for the first time period are displayed with diagonal hatching that slopes upward to the right, and the bars for the second time period are displayed in white without any hatching. Furthermore, the bars for the third time period are displayed with hatching that slopes downward to the right. This allows the time periods in which actual man-hour sales are smaller than predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold to be displayed separately as time periods in which the actual number of employees is equal to or less than the planned number of employees and time periods in which the actual number of employees is greater than the planned number of employees. This allows the manager to distinguish between these time periods and understand them clearly.

[0051] As a fifth modification, instead of displaying the man-hour sales difference, the display processing unit 116 may display a band representing each time period, and within the band, the first time period, the second time period, and even the third time period may be displayed in a distinguishable manner. FIG. 8 is a diagram illustrating an example of a display screen 420 according to this modification. As shown in FIG. 8, the display screen 420 displays a band representing the period from 4:00 PM to 10:00 PM, and the areas corresponding to the first time period, the second time period, and the third time period are displayed in different display modes. As such, it is sufficient that the first time period, the second time period, and even the third time period are displayed in a distinguishable manner for the user, and the specific display mode for this purpose is not limited to the embodiment. As another example, a line graph may be displayed with time on the horizontal axis and the difference on the vertical axis. In this case, the first time period and the second time period are displayed in a distinguishable manner based on the values ​​on the graph.

[0052] As a sixth modified example, the display processing unit 116 may further define a time period in which the actual man-hour sales are greater than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold as a fourth time period, and display the fourth time period in a different display format from the first time period and the second time period. Furthermore, the fourth time period may also be displayed in a different display format from the third time period. FIG. 9 is a diagram showing an example of a display screen 430 according to this modified example. As shown in FIG. 9, 5:00 PM is classified as the fourth time period, and the bar for the fourth time period is displayed with hatching.

[0053] As a seventh modification, the display processing unit 116 may display the actual manned sales amount on the display unit 41 instead of the manned sales amount difference. In this case, by checking the actual manned sales amount and the display mode for each time period, the manager can confirm whether there is any unnecessary work.

[0054] As an eighth modification, if the work manager device 10 is provided with a display unit, the display processing unit 116 may cause the display unit of the work manager device 10 to display the man-hour sales amount difference.

[0055] FIG. 10 is a diagram showing the configuration of a work manager device 10 according to a ninth modification. In this modification, the control unit 11 of the work manager device 10 includes a warning unit 117 instead of the display processing unit 116. The warning unit 117 issues a warning when, for a certain unit time within the processing period, the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold. Specifically, the warning unit 117 specifies a unit time and transmits information to the manager device 40 to inform the manager that, for that unit time, the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold. The information may be text information displayed on the display unit 41 indicating that the actual man-hour sales are smaller than the predicted man-hour sales and the man-hour sales difference is equal to or greater than the warning threshold, or an icon indicating this. As another example, if the manager device 40 includes a speaker, the information may be output as audio.

[0056] FIG. 11 is a diagram showing the configuration of a work manager device 10 according to a tenth modification. In the work manager device 10 of this example, the control unit 11 includes a predicted man-hour profit calculation unit 141 and an actual man-hour profit calculation unit 142 in addition to the functional configuration of the control unit 11 of the work manager device 10 according to the embodiment. The predicted man-hour profit calculation unit 141 calculates a predicted man-hour profit based on predicted man-hour sales. The actual man-hour profit calculation unit 142 calculates an actual man-hour profit based on actual man-hour sales. In this case, the difference calculation unit 143 calculates the difference between the actual man-hour profit and the predicted man-hour profit. Then, the display processing unit 116 classifies the time periods into a first time period and a second time period according to the difference and displays them in an identifiable manner.

[0057] Furthermore, the tenth modified example may be applied to the ninth modified example, and the warning unit 117 may issue a warning when the difference between the actual man-hour profit and the predicted man-hour profit is equal to or greater than the warning threshold.

[0058] Furthermore, the present invention can also be applied as a program or method. The above-described systems, programs, and methods may be realized as standalone devices or may be realized using shared components, and include various other aspects. For example, it is possible to provide a method or program realized by the above-described system. Furthermore, it is possible to modify the invention as appropriate, for example, by making some parts software and some parts hardware. Furthermore, the invention can also be realized as a recording medium for a program that controls the device.
