If you are a manager  or going to be then below points you should always consider.

Meet with your team members: Regular one-on-one meetings are critical to good management. These meetings have several purposes .

Prepare for the transition: This will become confusing and frustrating... perhaps not immediately, but managers are often pulled in multiple directions.

Figure out what is going to change about your role now that you are a manager.What significantly sets managers apart is the migration away from a concept known as "individual contribution." Managers are not, primarily, individual contributors. That means that you are going to be responsible for the work of others; your success depends on how well your team performs. You are now responsible for far, far more work than you could ever possibly produce by yourself . You can’t fix all the problems – don’t even try… that’s not your job anymore.

Identify your goals: What, specifically, are your measured goals? Do you have hourly, daily or weekly targets your team must meet; what about your new goals such as reviewing productivity? Write down everything and post it prominently . This will be your checklist.  Review your list frequently, with a critical eye, and revise it when necessary.

Document team activities: Your personal performance review will focus largely on your team’s performance so make sure you keep a written record of issues and accomplishments. This will be especially important if there are significant issues that arise. Problems are expected; how you and your team handle those problems must be a focus of your efforts.

Learn coaching: There will inevitably be times when you need to correct behavior. Learn to do this properly. If you do it correctly, you will get the results you want. If you do it poorly, things can go horribly wrong. 

Reward performance: This doesn’t mean money… although money is nice, it’s not a primary motivator for on-the-job performance. Recognition is much more effective
