Regular project updates
As project manager, it is your job to get regular updates from task managers, to ensure that the project is on track. You also need to report on project progress to the ‘Project Board‘ and let them have information about any emerging problems.
Your updates from task leaders do not have to be formal. They can be as simple as a regular telephone conversation about progress. You may prefer a more formal reporting structure, such as a one-page report. This could be in a traffic-light format, with task managers asked to say whether their task is on track (green), at risk of delay or problems (amber) or suffering delays or problems (red).
