Показать описание
Philip Marris, CEO of Marris Consulting describes briefly the Critical Chain Project Management (CCPM) approach.

Too often, the Critical Path Method (CPM) or the Program Evaluation and Review Technique (PERT) undergo time and budget overruns of 50% to 200% and specifications have to be abandoned.

Critical Chain Project Management (CCPM) has shown over the last 20 years (1997) that performance can be significantly improved.

The Critical Chain is defined by the longest chain of dependencies between tasks, but it also takes into account resources availability.

Task durations are redefined to remove local safety margins. Durations are "focused durations" in perfect working conditions. A big global "Project Buffer" is added to the end of the project. During execution progress is tracked on the "Fever Chart".

Critical Chain is used both for individual projects and for entire project portfolios.

Marris Consulting is a management consulting firm dedicated to manufacturing companies. Half of its assignments involve implementing Critical Chain.

This video succinctly condenses 90% of the CCPM knowledge in a unique and efficient manner. In just 5 minutes, Phillip articulates the logic behind CCPM, saving us valuable hours that would have been spent deciphering the same concepts independently. Grateful for Phillip's insightful explanation!

This perfectly describes CCPM, or what i consider Production Scheduling. Such a simple tool that ERP software systems must offer, (and don't).

Excellent video, thanks Philip! I noticed the buffer is 1/2 of the work not 1/3. Was it just an estimate for the example? thanks!
