Software Peter principle

The Software Peter Principle says that software developers have a tendency to help themselves get promoted to higher positions within a company even if they don't have the skills or knowledge to do the job. This happens because it's easier for them to get promoted than to learn the skills needed to do their current job more effectively. As they continue to rise up the corporate ladder, their knowledge and abilities might not keep up with the position they get promoted to. That can lead to them not being able to do the job they were promoted to, and that can hurt the company in the long run.
