Have seen it in the education sector. Good teachers get taken out of the classroom, where they are doing a great job, and put into management positions, where a different skill set is needed. Some make the change and some don’t.
Either way, daft way to select them for management.
In the greasy pole world of corporate management, the same problem exists as in our parliamentary democracy L IMVHO. In politics, the skill set to get elected is not the same as the skill set needed to go earn. Blair/Brown is a very good example,of this.
In the corporate world, the ones that rise to the top are those good at doing the politics not the ones good at management per se or, higher up, strategy.
