Design
method
1. Determine the goal first, reverse the needs and problems from the goal, and then seek solutions.
2 Matters needing attention:
Goals and needs should be based on reality, serve high-end households, have practical application value,
pay attention to the object of the report: listen to the plan The object of the report usually does not directly participate in the development process, and does not know the status quo of the system, existing solutions, why problems occur, etc., so it should be as clear and detailed as possible in the document, and can be supplemented where necessary Swim lane diagrams, flow charts, interface screenshots, DEMO presentations, etc.;
PPT contains the following parts
1. Background
description of problems or needs: describe the status quo, what problems have arisen, or what needs cannot be realized, the value and significance of solving the problem or realizing the needs (such as sales promotion, performance improvement, saving time and cost, saving manpower cost, etc.)
Classify requirements: classify problems or requirements, for example, according to the role of the proposer (unit leader, general customer, R&D team, etc.), according to the function (for example: for modeling, for data analysis, for report making)
2. Problem analysis
Problem traceability: what causes it, what is the root cause, whether it is a real problem (for example, whether the problem can be avoided through human operation) the
impact: analyze the impact of the problem, in addition to the superficial impact, there are deep-seated
3. Solution Aiming at the problem, summarize the solution, including: detailed
description of the solution, UML context (refer to the link http://blog.csdn. net/zhaxun/article/details/124022450), the advantages and disadvantages of the scheme, and what method to use to achieve it. You
can analyze and compare various schemes, describe the advantages and disadvantages of each scheme, risk items, etc., and finally draw the comparison result (with the help of Summary of the conclusion of the first chapter)
4. Conclusion
From what angle does this plan start, what problems are solved, and what value can it produce (such as sales promotion, performance improvement, saving time and cost, saving labor costs, etc.)
