Method of Construction 04

the eighth chapter of the Law of construction is mainly about the analysis of requirements in software engineering, for software, we all know that customer demand is the most important. We must understand the type of software requirements and find their stakeholders is the basis for the success of their own software, in addition, when users express their own needs, we further professional analysis, for users will not superfluous, because there may be many functional users do not need. And all this is based on the user survey, you can obtain information from the network and the actual interview, and to confirm the positioning and priority of the function, to complete the strategic significance of the software, resulting in benefits. The software team takes the following steps to get people's needs: acquiring and guiding requirements, analyzing and defining requirements, validating requirements, and managing these requirements in the SOFTWARE PRODUCT lifecycle. The most important way to understand customer needs is the questionnaire survey, in the user survey method often there are some common errors, such as problem 1. The definition is inaccurate, 2. Use ambiguous adjectives, adverbs to describe time, quantity, frequency, price, etc., 3. Let the user spend extra effort to answer questions, 4. Problem-oriented , 5. The issue concerns user privacy, trade secrets or details of the company where the user is located. The questionnaire can have the following questions: 1. Full open question 2. Two choice questions 3. Multiple choice question 4.     Product functionality requirements The product must realize certain functions, the product development process requires that the software development process must meet certain constraints, non-functional requirements are not a single software module can be satisfied.

the Nineth chapter of the Law of construction project Manager, refers to the establishment of the project manager responsibility system as the core, the implementation of the project quality, safety, progress, cost management of the responsibility to ensure that the overall improvement of project management level of the important management positions. The project manager is the person who is responsible for the successful planning and execution of the project. PM's ability is important. PM is a good pm that has the ability and is approved by everyone. Here PM is an important role in promoting a team to work quickly and efficiently, but also need to be able to work with others, equal. A good PM requires strong requirements and capabilities: 1. Ability to observe, understand and learn quickly, 2. Ability to analyze 3. A certain professional ability, 4. A certain professional ability 5. Ability to introspect. These are key to the team's success and very important. The project manager is the leader of the project team, and the primary responsibility of the project manager is to lead the project team to complete the project work and satisfy the customer in time and within budget. For this purpose, the project manager must lead in a series of project planning, organization and control activities to achieve the project objectives.

The tenth chapter of the Law of construction mainly introduces the typical users and scenes. Typical users can include content: 1. Name (the more natural the better). 2. Age. 3. Income 4. The proportion and importance of the users represented in the market 5. Typical scenario for using the Software 6. Environment for using the software/Service 7. Life/Work 8. Knowledge levels and competencies 9. User Motivation 10. User Preferences. Use cases require a planning instruction and a functional specification. Provides templates that define typical users and scenarios to help us emulate. The performance test case design begins with the analysis of typical scenarios in the user's reality, and then is designed with reference to typical scenarios. There are three types of common user scenarios: Usage scenarios for different time periods within a day the usage of most systems changes over time on the same date. The scene of the system running in different periods is the basis of the design of the large data volume performance test case. Scenarios in different business modes the same system may be in a different business model.

The above is my summary of the law of Construction 第八、九、十 chapter.
