To be a manager means you must guide, direct, instruct, mentor, discipline, control and lead other people. And you must do all of this while you meet the productivity requirements of the business. To be a good manager, start with a clear understanding of what you are tasked to do, which is much more than just the work. Focus first on the people who report to you. It is the people who will make the success or the failure.
Process is important, but people are more important to success.
Begin by listening. Interview each person privately. Ask about their background. Ask them to explain what work they do, and how they do it. Ask what they would do differently if they could.
