Picture yourself as a project manager intent on bringing CCPM to your organization that has historically used classic critical path project management

How would you convince your project team to develop 50% estimates for their project contributions rather than the 90% estimates they have used since they started with the company?

This will require a culture change for all project participants. The idea is that the project must work in a "no blame" environment and that all parties agree that it is literally a coin flip as to whether their piece of the project meets a 50% estimate. Answers will vary as to how to bring about the culture change. Some students may cite a need to manage a couple of projects this way before team members accept the new mindset. Training exercises, such as the Deming Red Bead experiment, might be used as a lesson, albeit as a counterexample. The project manager may take the estimates provided by the project team as given, then run a parallel analysis using the CCPM approach, to show the team after the fact, how things would have worked out — or — hold his team to their estimates but report to his superiors a CCPM schedule.
