Software Development-People mobility

Software development is not a simple thing.

Suppose a program ape is like a cabbage, marking a price and selling it on the market.
Well, software, not, a bunch of cabbage piled together on the OK.

When people stay in one place for a long time, they may flow.

After all, the world is so big.

However, once the software system has been developed, it should be implemented online.
So the flow of people should never be like cabbage. A one-by-one. They overlap each other, and this overlapping part should not be less than half a year. This software system is controllable.

Otherwise, the stitching is very fragile.

When people are moving. This overlap should be maintained.

In this picture, these people are very pitiful. Because they have no successor.

The successor is very important. For the stability of the software system.

No matter what the work, should guarantee. At least 2 people can operate the business.
This is human nature for talent. Otherwise. The man is finished. He may be on weekends, or whenever the system fails. He must, immediately to the computer to deal with. This way, he will stay for a long time. So where do you expect the system to be stabilized?
