What methods do you use to assess your team's performance?

An assessment of your team performance is really important and there are various methods available to assess a team’s performance. If I have to asses my team’s performance, I will do it with consistency with reports like daily, weekly, and monthly work reports. I will always ask them to contribute with their ideas in the team so that I can get assured who is giving his/her efforts to make the company grow and deserves an appreciation. I will suggest self-monitory ideas so that they can analyze themselves and prevent themselves from the thought that they are not capable enough to do that work. And at last, I will maintain the accountability of work.
