People's Month myth read Note 01

What is the book of the man-month myth about? I probably follow the CMMI Project management, engineering and support process in three dimensions. According to the human, method tool technology and process three elements were combed. The contents of these aspects are all involved in the book. Project management can be seen in project estimation, organizational structure and personnel role scheduling, team building and communication, historical data accumulation and modeling, software development methodology, risk and problem management and other related content; In software engineering you can see that architecture design guarantees conceptual integrity, overall and partial, spatial skills and program structure relationships, The method of product integration and the design idea of eliminating defects, we can see the construction of documents and processes, the support and efficiency of software development tools for software development process and the selection of tools.

Back to see, found in the book still most of the content involved in the team, people and communication. For large-scale software engineering projects still emphasize the importance of people, at the beginning of the development of the professional fun, followed by the importance of communication through Babel, in the surgical team to talk about team formation and division of labor. These involve people and interactions in the team, and only a communication team with a positive mindset and passion can make a great team. From the last no silver bullet, again affirmed that the development work is a high intellectual mental work.

The concept of completeness requires the design to be implemented by a person, or very few people with mutual understanding. But progress pressure requires a lot of people to develop the system. There are different requirements for large-scale projects, such as: separating the work of the design method and the architecture from the concrete implementation is a powerful method to obtain the concept integrality. I witnessed its great success on the I BM ST RET CH Computer and the 360 computer product line. But at the same time I have seen this approach in the development of 360 operating systems, due to the lack of widespread application of the failure suffered. The architect of the system, like the architectural structure, is the user's agent, his main job is to use professional technology to support the real interests of users.
