Sometimes the best ideas come from the people close to the problem.

Have you found that some people's ego is too big and they think they know it all and fail to take good advice from anyone. The best management advice I ever got was from my uncle who was a VP of steel company. He would spend his first hour of every day talking to the workers on the factory floor. He always asked the same question "What can I do to make your job easier " If he got a idea he would implement it and test and measure results and had a reward system for the ideas that worked. This was in the 1960's long before union - management team work was a popular idea. The people closest to the problem often have the best ideas how to fix them if the leaders are humble enough to hear them
