5. Promoting the wrong people
Rewarding your top technical talent with a promotion into management might seem like the right thing to do, but when that IT pro is not ready to give up constant, hands-on technology work in favor of more people-oriented management duties, it can be a mistake you’ll regret on many levels. Resentment from former peers, the challenges of new management duties, a found distaste for the new role -- all could lead to poor performance. Worse, the new manager might feel compelled to cling to the ill-fitting position because the old position might no longer be available. Management training can help avoid such disasters. But use your gut. Either the aptitude is there, or it isn’t.
