1.1 individual software process
A software engineer's task is to deliver high quality software products at a scheduled time and progress. For them, the most important personal assets are always the ability to meet the contract requirements with high quality products. The Personal Software Process, PSP is designed to help software engineers have completed tasks, improve personal capacity, which tells how to apply advanced detailed estimates and programs to their daily tasks, tell people how In accordance with the plan to track the implementation of the task, explain how to use the defined process to guide the work.
PSP provides a structured framework and method for improving personal skills needed by software engineers. Of course, the key to the problem is not to require some personal skills, but how long it takes to master these skills and whether they can often use them. If the software engineer has to master this skill in the work. This not only has a lot of cost and time, but also has great risk. PSP will accelerate your process.
1.2 process improvement
PSP is a process that requires stepwise improvement.
When Watts S. Humphrey is serviced, you must learn the machine gun shooting. When starting training, use the shotgun to make the pigeons, Watts' results are very poor, and efforts are still not improved. After a while, the instructors have observed Watts, it is recommended that he shot with left hand. As a person who is used to right-handed, Watts is not used to it, but after practicing a few times, Watts' results is almost always nearly excellent.
This example shows several questions. First, you have to diagnose a problem by measuring, it is easy to see that Watts must be adjusted by understanding Watts hits a few pigeons and off. Then, objectively analyzes the measured data, by observing the shooting of Watts, the instructor can analyze the process of Watts shooting - the upper, in place, track target, aim, final shooting. The purpose of the instructor is to find that there is a problem in the steps of Watts. It is found to find the problem, so the suggestion is to find the left hand shooting.
Finally, it is also the most important, it is its own change. The process improvement is very difficult because people don't want to try new things many times. Their traditional habits look natural, so that there will be helps to do not believe that changes will help. Watts always uses the right hand, never thought about what the left hand shooting will look like. But since Watts adopted the advice of the instructor, his achievements were improved.
Defining the measurement method is not an easy thing, but it is always possible. First define the measurement method. The data must be collected and analyzed after the measurement method is specified. If you need some improvements, you should analyze the work process and see where it needs to be improved. Finally, you must really improve the improvement.
If Watts do not improve his shooting process, its achievements will not change in a few years, and will not be an excellent gunner. Only measurement does not have any improvement, and there will be no improvement only. The resulting result is determined to a large extent. If you still work according to the old way, the result will be old.
Improved mode of work is the same as the steps of the Watts study shooting. They are not complicated, as shown in Figure 1:
Define quality objectives
Test product quality
Understanding process
Adjust the process
Application adjustment process
Test Results
Compare the results with the target
Cycling and continuous improvement
Baifu is the ultimate goal
Be bad, need to improve
What changes need to be in the coach observation
Coach recommendation with left hand
Watts played a few wheels with the left hand
Reconscent hits and the number of deliners
The results are greatly improved
The process is simple and does not require this step.
