 All five members of a project team add 15% to their individual serial activities as a safety margin and submit their time estimates to the project manager. The manager adds the activity length estimates together and adds 10% for his personal safety margin. Then, anticipating a cut by top management, adds another 10% to his final project estimate. Much to his surprise, top management cuts 30% off his time estimate. How much of a cushion is now built into the project?
