The most common project risks in software development are poor requirement analysis and poor project design. A good project planner can eliminate the major risks as early as possible, so that most of the work of the project can be carried out as smoothly as possible, so the preparation work tends to focus on improving demand analysis and project planning. ----------- Chapter 3.1 P25
My opinion: when I saw this passage, I thought of two projects in the school. I took the lead. at that time, there was too little experience, especially a mess of demands. as a result, there were too many projects to be changed later, but why did the demand become poor. I personally think there are several reasons. first, we were not fully prepared for the expertise field. When dealing with customers, we thought about each other. second, I didn't pay too much attention to the demand at the time. I just thought about coding early, so I was too anxious. of course there are other reasons. I hope I can pay more attention to the demand analysis in the future.
