My management style is to listen to every complaint about how things are being done. Even from whiners. However, if someone came up with a criticism that I had not thought of, my reaction was to put that person in charge of fixing the problem.

My belief is that if you are smart enough to find a problem, there is a good chance you can also find the solution. Further, it can create a de facto “task force” as the “Person in Charge” starts reaching out to others for ideas.
