14th Chapter Huoqixiaoqiang

First of all, why is there a progress deviation? Because there are always all kinds of things happen, today drag a little, tomorrow drag a little, the more drag the more deviate. Then we begin to introduce methods, milestones, must be clear oh, unclear milestones will also dampen morale. Milestones are a sign of what is done, making it easier for the boss to verify. Then the author said, some programmers look at their own progress is slow to think, anyway, the other part of the fall, it is not urgent. The author has a pert chart, (presumably, a path map of discrete mathematics), and people will know that they are trying. Then the manager and the leader, the manager afraid the boss quit him, will cover up some things, try to make up. It is said that there is dirt under the rug. Bosses can reduce the clash of roles and encourage state sharing. Or pull the rug open.

The other side of the 15th chapter

The author is talking about how to produce a good document. First of all you need to know what kind of document, the use of the program mainly has, the purpose, environment, scope, implementation functions and use of the algorithm, input and output format, operation instructions, options, run time, precision and calibration. Then there is the validator, which modifies the program. Not much has been said too much. Then we introduce a program document: Flowchart. In the end, it is the writing of the code: to have comments, to have spaces and so on.

16th Chapter No silver bullet

There's no silver bullet. There is no way to make software cost as fast as the cost of computer hardware, but there is a certain innovation to improve production efficiency. Due to the nature of the software itself, complexity, consistency, variability, invisibility, there is no possibility of invention and innovation. There have been some breakthroughs in solving minor problems such as high-level languages, time-sharing, and unified programming environments. Finally, there are some hopeful silver bullets: Ada, AI, expert system, graphical editing, program verification, environment and tools.
