I will talk about customer agenda tomorrow Today, I will continue to develop yesterdays thought on getting unpleasant information. I go out of my way to hear people in the organization who I know have contrary thoughts. As a young manager, I even let one manager get out of line. Contrary thoughts should be heard and considered for what gem is within them. These people should show respect to you and should implement once you have made the decision, but they should be valued for their thinking and not punished for being in groupthink.
Your people should have alignment and a sense ownership. Ownership leads to more thoughts and even conflict. Seek it out. Finally, cut it off and implement with force in your chosen direction. Demand full support.
Then you will be a great leader in this area.
