James,
Defining roles is a good strategy. In addition to defining the role, you should also outline what success looks like in that role. So often, people get shuffled around without know why. Communicating expectations at the time the assignments are given is crucial for success. At each meeting, have the team members bring a list of the assignments, their progress towards the goals, and any stumbling blocks that you, as the manager, can help move. Your job is to communicate the path to success and help your employees achieve it.
