Recently, learning the function point analysis, the information learned is the book of Qiaoling. In order to overcome the problem that he is not serious, decide to make a reading note. So there is this thing.
The book is written to the company's leadership. We directly talk about the steps of functional point calculations, this is the calculation of content function points in Chapter 6. A: Function point calculation The first step is to determine the calculation of the function point of the function point. There are three types: 1. Development project function Calculate Measurement of a new application if this system is to replace the old system. Then, in addition to the functional point of the system, it is also necessary to convert data from the old system to the function of functionality. This measurement is gradually refined, over time continuation and project progression. Get more and more documentation. These more contribute to more accurate computing function points. According to the different development methods used by the project, you can perform in demand, detailed design, test, implementation, maintenance and other stages. 2. Upgradeability Project Function Calculation Use to measure modifications to existing applications. Includes new features, delete functions, and changing features. The calculation must reflect changes in functionality. 3, the application function point calculation is to calculate the function point B: Determine the calculation range and the application boundary to determine the principle of the boundary 1. The boundary is in the user's point of view, users can use their own language To define the scope and business function of the application 2, judging whether the division of other applications is mainly due to the segmentation of the business level, not the technical level 3, for independent applications in a large system [is independent of each other Module], the function points of mutual calculations are calculated separately, then synthesize the function point of the entire system. When exams between different applications, ILF and EIF are also relative to independent applications. Not the entire system. C: Determine all data features [internal logic file ILF and external interface file EIF] and its complexity D: Determine all error functions [External input EI, external output EO, external query EQ] and its complexity 1, one EQ can Query data E: Get unmodified function point count f: obtain value for value adjustment factor G: Calculation has been adjusted function point count based on 14 system basic features
