It is misguided to think that the formal leader (like me) will have the best idea. Most of you have forgotten more about the machinery that you use daily than I will ever know. Why should I be trusted when machines are being discussed?
Therefore, if I am the leader, it is my job to find the best idea, not have the best idea.
So, no matter who you are, speak up when you have a good idea or a good solution.
And, if you are the leader, make sure that everyone is heard. It may just get us to a better place.
