Description

Technical Field

[0001] The present invention relates to the technical field of development demand management, and in particular to a demand closed-loop long-chain management system and method. Background Art

[0002] Excel demand management tool is the most familiar and simplest management tool. Excel is suitable for maintenance by a single or a small team. It is easy and quick to use, and can be classified, sorted, and tracked. It can also perform simple quantity statistics and visualization. When the amount of demand data is extremely large, it does not support collaborative processing by multiple people, and Excel data is prone to human confusion or loss.

[0003] Worktitle is a project management system with a very high domestic market share. Although it is not a dedicated demand management system, it has a unique management method in demand management. It has a demand pool, collects requirements widely from members across departments, customizes process configurations, adapts to complex process situations, and configurable demand priorities to provide scheduling that changes with the situation. However, it lacks risk or problem traceability. Summary of the invention

[0008] The demand acceptance module provides a friendly operation interface for product managers to decide whether to accept the demand based on the demand information and designate a person in charge of the demand when accepting the demand;

[0009] The demand scheduling module provides a friendly operation interface for the demand manager to set the start and end time of demand analysis, demand development, demand testing and demand release according to the demand information, and designate demand analysts;

[0010] The requirements analysis module provides a user-friendly interface for requirements analysts to split the original requirements into sub-requirements that can be identified by R&D personnel;

[0011] The demand development module provides a friendly operation interface for R&D managers to separate development tasks according to sub-demands and assign R&D personnel. It also allows R&D personnel to build corresponding iterations.

It also automatically generates and distributes test tasks covering all requirement points through versions. It also allows testers to associate test cases with specific sub-requirements and develop detailed test plans.

[0013] The version release module provides a friendly operation interface for R&D managers to create a formal version release process after the test task is completed and submit it to the reviewer. If the review is passed, the release process is completed and archived. If the review is not passed, the version is returned to the R&D manager.

[0014] The version launch module provides a friendly operation interface for project managers to initiate version launch process applications;

[0015] The report display module provides a friendly display interface for statistics on the overall progress of original requirements, sub-requirements and development tasks through reports, and displays the acceptance rate, analysis rate, R&D rate, testing rate, version release rate and version launch status for project managers, product managers, demand managers, demand analysts, R&D managers, R&D personnel and testers to view.

[0017] The product manager views the demand information through the operation interface provided by the demand acceptance module, and judges the rationality of the demand based on the demand description, expected release time and online time of the demand. a) If the demand is reasonable, the product manager accepts the demand and designates a person in charge to handle it later; b) If the demand is unreasonable, the product manager rejects the demand and gives the reason for rejection based on the demand description, expected release time and online time of the demand, and sends it to the project manager via email or SMS.

[0018] Optionally, through the operation interface provided by the demand development module, the R&D manager first prioritizes the sub-demands split by the demand analyst, then splits out at least one development task according to the sub-demands and their priorities, sets the start and end time of the development task according to the start and end time of the demand development, and then assigns the development task to a specific R&D personnel;

[0019] R&D personnel complete assigned tasks by, on the one hand, setting a batch of sub-requirements and decomposed tasks through the requirements development module to build an iteration, with one iteration serving as a development cycle; on the other hand, managing the code and documents generated during the development process through the requirements development module to facilitate subsequent testing and maintenance.
