When I first became a “boss”, it used to irritate me that people who reported to me did things slower than I would have done them. And, worse than that, they did things differently.
It was one of the first lessons of leadership that I had to learn. That different people do things differently. And the way they learn to do stuff quickly is to practice, practice, practice.
So jumping in and “showing them how”, except maybe just the first time, is generally counter-productive.
I was discussing this syndrome with a client yesterday, who has a direct report who has never escaped from this trap, always taking over on the basis that if you want a job done well, you do it yourself.
The deeper problem is: if we don’t learn how to trust and delegate, to let go, we don’t grow ourselves.
