Systems development and project management foundation
1 test sites Software Development Model
Test method [analysis]
This test center to test the basic method is to determine the use of several common software development model scene
Points [analysis]
1, the waterfall model: a clear demand, or in the secondary development, have previous experience of successful projects can use and reference
2, V model: waterfall model variant, the associated testing and analysis and design, analysis and design verification strengthen
3, the prototype - evolution model: first come up with the existing system as a "sample", through the "sample" continuous improvement, making the final product is required for customers
4, spiral model: waterfall model and the evolution model to combine, adding risk analysis of the two models are ignored
Remarks [coaching]
By keyword, identifying usage scenarios of different models
2 test sites Project Management
Test method [analysis]
This test method is a test center substantially PERT chart is given, so critical path candidates to identify, schedule, the start time or the latest relaxation time
Points [analysis]
1, FIG each path, the longest path is the critical path for the duration of time that is
2, the time period will be less than the other path
3, in the case does not affect the duration of a point on the other path can take a break, and then start it does not matter a few days later, this time is the relaxation time. However, the relaxation time plus the total time period of the path can not be greater than
4, normal point on the path start time, i.e., plus relaxation time is the latest start time.
Remarks [coaching]
By doing problem determination method
