First, leaders must develop an atmosphere of open communications within their group. Leaders must set this example by encouraging input and feedback from all levels. Further, leaders must have the ability to accept criticism well, and not become defensive when receiving it. They must attempt to understand the viewpoints of those providing the feedback before they make a judgment. If the feedback is valuable, it is critical they modify their own behaviors accordingly.
Secondly, good leaders need to fully listen to what others are saying when discussing an issue. Not only does this mean hearing and understand what is being said, but also what is not being said. Good leaders must be able to read and understand non-verbal communication. They must show empathy for the individual and allow the individual to fully express their feelings and thoughts. Good leaders embrace the power of silence. They must resist the temptation to fill the void by jumping into to problem solve immediately. Often this may cut a person off in the middle of their discussion without fully hearing all that is on their mind.
After the person has expressed all their thoughts, good leaders will ask follow up questions to drill down to the core of the issue. Then they begin the process of problem solving. However, a truly great leader will ask questions which lead the other person into discovering their own solutions to the issue. Sometimes this isn't possible, but when it is, the results are empowering.
