Research the topic. Gather information on self-managed teams from both print and online resources. To develop a strong thesis, you must be well-versed in the topic, so gather as much information as you possibly can.
Conduct interviews with individuals with personal experience. If you know people who have worked in organizations that employ a self-managed team model, or individuals who have taken part in self-managed teams, speak to them and ask them about the experience. This face-to-face information-gathering process could prove an effective way to get some insider information on the topic.
Form an argument. A thesis is, by its very nature, an argument. Decide what you want to prove about self-managed teams to create your argument. You could, for example, say that self-managed teams are highly effective or, conversely, largely ineffective.
Gather supports for your argument. Flip back through your research to collect supports before you take the time to actually compose your formal thesis. By doing so, you can ensure that enough information exists to support your thesis and that writing it wouldn't prove a waste of time.
Compose your thesis. Reference the information gathered throughout your thesis to prove the points that you are making and back up the stance you have taken on the issue at hand.
