This interview was conducted by zdnet's Li Ning editor during the 2007.03 month. [Editor's note]I recently read a series of articles on the Internet titled "The Immortal wolf-I read The Mythical man-month. Zhou aimin's reading experience on "man-month God. A weighty book in software engineering describes Dr. Brooks's project management experience in the IBM System/360 family and OS/360. In his series of articles, Zhou aimin used his architect's experi

approved by the SQA team to enter the next stage. In this way, the waterfall model provides prescriptive documentation to ensure that each stage is well-done with mandatory requirements. However, it is often difficult to do so because the entire model is almost document-driven, which is difficult for non-professional users to read and understand.The waterfall model is illustrated below:As can be seen, the output of demand analysis, "Requirements Spec

As a start-up web Developer, we are often intimidated by a variety of tall design platforms. In fact, the current variety of solutions on the market can help us to solve the coding problem, but also guide you to master the technical knowledge of website creation. Here's a look at the 10 leaders:1.TOWebWhat do you want your website to look like? How is it laid out? Before we can make the site look real, it often takes hours to build and

example, the car engine is not a strong project management ability can be studied, the core of the technical personnel are treated to determine its success or failure. Some software projects are the same, not the project Manager management ability, the project will be successful, and its professional ability is also likely to be necessary rather than sufficient conditions. However, no matter what kind of p
