What is the essence of the contradiction between product manager and programmer?

The function, quality, release time and resources required for a product cannot all be closed conditions, otherwise there may be no solution. The resources to be invested and the release time are generally determined by the big boss, so the product manager, development manager and quality manager can only love each other and kill each other in the three choices of "cutting functions", "lowering quality requirements" and "programmers working overtime and dying". The root cause is: high-level satellites play the Great Leap Forward, and then the masses have to fight against the masses. Buddha said: It's fun to fight with others. For programmers, many times the problem is that PM can't prove its existence value. There are several possibilities for PM to prove its value:

1. Color's product record, its name is a brand, and programmers know that following you can succeed.

2. Fake products will lead to disorientation and out-of-control projects, which can easily prove why you need to exist.

3. Explain the truth in a way that programmers can understand, and convince programmers why your method of managing products is right, and why programmers themselves can't do as well as you.

There may be other ways for a PM to prove its existence value, but if it can't be proved, programmers will regard PM as a pure overhead. It is impossible to objectively measure the value and burden that PM brings to the product team, and what others' subjective evaluation is. If the programmer's subjective evaluation of PM is that the burden is greater than the value, then this PM has no meaning of existence. The core reason is that good product managers are always out of stock. Of course, excellent programmers are also lacking. Since they are all out of stock. The product manager is the key to determine the efficiency of a company. A mature team of a product manager in a mature company means the soul and center. The programmer's brother just represents the boundary between execution and ability (if you don't understand, just look at Joe's leader Ma Huateng and Zhou Hongyi): a product manager with little knowledge and two thoughtless decisions, his workload may only increase by three times, but he gives the programmer 1-1 times the workload.
