Editor's Note:

In December 2012 we published a Guest paper: Critical Chain Project Management by Skip Reedy. In it he described the management of constraints concepts that underpin the Theory of Constraints that is typically applied in manufacturing production management and is now advocated for project management. You can read his previous paper here:

As a reminder, Critical Chain Project Management (CCPM) is a method of managing any kind of project by focusing on quickly completing tasks (and the project). It provides exceptional current status so delays and problems can be resolved and mitigated early.

In this case, and the postscript, of actual successful projects, Skip says that he worked on the 777-300ER Derivative Airframe Design for over a year. He was one of five Boeing internal Critical Chain consultants on the program. The budget for the airframe derivative was $500 million.

If you take the aggressive program duration, and calculate the actual duration based on it starting two months late and finishing early, the program finished 26% early. Skip also believes that the project finished 10% under budget. He says it was amazing to see how easily it got out of trouble.

These cases set out to demonstrate Skip's support for Critical Chain Project Management.
