"The best and the worst performance in productivity an average of 10: 1, with a 5 on the speed and space:! 1 of striking differences in short, the programmer productivity of $ 20,000 / year could be ¥ 10,000 / Year 10 times the programmers' "conclusion is simple: if a person's 200 projects, 25 have developed the most capable and most experienced project managers, then dismissed the remaining 175 programmers, project managers program to develop "but this approach has a problem:." for the integrity and efficiency of the concept, the best designed and developed by a small number of competent personnel, and for large systems, it requires a lot of manpower to make the product to meet the requirements in time. "in this regard" Harlan Mills proposal provides a new, creative solutions .Mills recommended that each part of a large-scale project addressed by the team, but the team in a similar surgically formation, rather than rush forward. that is to say, the opposite approach taken issue with some part of each member, to break down the problem by one person, others give him needed Who, in order to increase efficiency and productivity. "
It's like a surgical team, penned by the attending physician, other auxiliary personnel, their duties and have completed surgical team.
Conceptual integrity is the most important system design consideration reflects a coherent series of design ideas, each part of the design consistency. The user can feel the integrity of the concept of ease of use, all Macintosh applications such as unified interface. In order to achieve conceptual integrity, must be implemented at the time of Software Architecture Design aristocratic despotism, let a few architects to determine the overall architecture, there is no ordinary programmers say. "In fact, the implementation details also need to be as creative, equally new ideas and remarkable talent." But if we can be noble, why strenuous efforts in the manufacturing process it?
