Software Engineering: Research Methods for practitioners (5th) Part 1 product and process Reading Notes

I borrowed two books from the Provincial Library: Software Engineering: Research Methods for practitioners and software process improvement.
1. Traditional Waterfall Model:
Analysis-> Design-> code-> test-> Maintenance
Although the actual projects are rarely carried out in this order, this idealized software survival model plays a positive and important role in software engineering and is the most widely used process model. Although it is determined that there are many defects, it is obviously much better than the random development status.
2. Software Evolution Process:
After a period of Software Evolution, business and product requirements change accordingly. It is unrealistic to go straight to the final product path. The pressing market term makes it impossible to complete a complete software product, but you can submit a limited version first. The core product or system requirements can be well understood, but the details need to be further defined.

PS. The computer collections of provincial libraries are not purchased by professional technicians, so many good books cannot be found. The translation of the previous book "effective methods of software testing" is a waste of time. I do not know whether it is the reason for translation or the reason involved in the original book. In addition, there are almost no books on CSS, and only one book has no practical effect. In China, I don't know who has pieced together to write an outdated book.
