Senior leaders who promote their star performers but end up watching them struggle with leading their technology team are typically doing one of these three things.

* They are confused why a star performer is now a low performer as the new leader of their technology team.
* They have decided to let their new leader "sink or swim", expecting that they will swim BUT they are drowning.
* They are watching their new leader flounder and pretending to have it all together, but the team and even the senior leader can see that they are doing a terrible job pretending and losing credibility at the same time.
