The relationship between the project manager and the programmer

There is a common analogy between software engineering and building engineering, which is, in general, really similar. But to think carefully, there is a big difference between them. Software engineering and Construction engineering can be said to be a kind of artistic creation, but the biggest difference between them I think is: the construction of the artistic factors suspended in the design drawing out, the construction staff's task is to follow the drawings to carry out, and there is no room for creation. But the artistic creation factor of software engineering is throughout, even after detailed design, in the coding process, how to make the program concise and efficient, improve the future maintainability and so on need programmers to play their intelligence. A function interface is defined, and after the function is determined, how the internal implementation of different people write may write a completely different effect of the program.
So the relationship between the project manager and the programmer I think is different from the relationship between the architect and the builder, it's more like the relationship between the band conductor and the band actor. The task of the band conductor is to master the rhythm and lead everyone to step forward in unison. He doesn't have to play the cello, the violin, the trumpet and the drums. The project manager is like this, he is not necessarily both Java, and will. NET, and proficient in the database, his task is to grasp the needs of customers this main line, the management of progress and quality, coordination Group of personnel. And programmers, not just like builders, can simply build bricks and mortar, and they should play beautiful music (beautifully written programs) under the direction of the conductor (project manager), like the band's actors.
