Improving communication within a small team

You are the manager of a small department within a local government. You want to develop processes for effective decision-making with your newly assembled leadership team, but you want to ensure that you are not acting in an overly authoritative manner.
 Determine different decision-making tactics that would be more appropriate for improving communication within a small team or group of about four to six mid- to high-level managers.
 Discuss the different types of power that you could conceivably employ in coming to the most appropriate decision-making processes.
 Differentiate between the sources and exercises of power that would be most appropriate for this group in the context of public administration organizational behavior.
 Provide an example from your own personal experiences of positively engaging in decision-making processes when you have not been the manager or in charge of the decision-making process.
