Classic story of project development: Professor's pants Analysis

Professor's pants

A professor carefully prepared a speech at an important meeting. The high specifications and scale of the meeting were the first time he had ever met. The whole family was excited for the Professor's face. For this reason, his wife bought him a suit. During dinner, my wife asked, "Does my suit fit ?" The professor said: "The upper body is good, and the trousers have two centimeters long. You can wear them !" In the evening, the Professor goes to bed early. My mother couldn't sleep, wondering how the trousers could work after her son gave such a grand speech. She rolled over and got out of bed, cut off her trousers and legs, sewed them and fell asleep with peace of mind. At half past five in the morning, my wife woke up and remembered her husband's trousers. She thought that the time was too late, so she took the trousers and cut off the two centimeters. She sewed them and made breakfast. After a while, my daughter also got up and saw her mother's breakfast was not ready. She remembered about her father's trousers and thought that she could do something for her father. Then she took her trousers and cut her pants by two centimeters, result ......

This story shows that the management in project development is chaotic, unorganized, and undisciplined. IfProfessor's family is considered a development team.Then, the professor should be the manager of the development team. When such a problem occurs, the manager has the greatest responsibility. Without a reasonable division of labor, the manager can skip programming, just as the professor doesn't need to fix his pants, but he should make a division of labor. All the members also encountered a very big problem. Without notifying others, they modified others' things without permission. in the project development, they showed that they did not write their own code and made any changes, just as the trousers are professor's, only the professor has the right to modify them, and others can only be modified after being authorized by the professor. The final result is that the trousers can be worn, and the trousers cannot be worn after being repaired, just as the program can be used. After modification, the trousers cannot be used and will be voided.

This story illustrates two very important principles in development:The code you write is tested by yourself, and the code you write is modified by yourself after an error occurs.The first principle is no problem. The professor did not give his trousers to his wife or daughter to try on. The second principle has a major problem. It cannot be changed unless it is his own things.
