Do public sector managers have to participate in the policy-making process? Why? How? Isn't it the manager's job to just implement policies made by elected officials? Why do they have to be involved in policy-making, and what kinds of skills and resources do they need to develop?" These questions have been actively explored throughout the development of public administration scholarship. Identify the major perspectives on these questions either of the key theorists who have discussed the "proper" role of the public sector manager or from the key era(s) in public administration where that "proper" role has been debated. Include the strengths and weaknesses of the theoretical or historical perspectives you include.
