Critical chain project management (CCPM)

Critical Chain Project Management (CCPM) is a method of planning, executing and managing projects that are using the uncertainty as a possibility rather than as a threat. The methodology was developed by Dr. Eliyahu M. Goldratt in 1997. Goldratt´s Theory of Constraints (TOC), and the following book called "Critical chain", was the root for this method. This theory consists of a collection of methods and algorithms to describe supply chain management. An objection is to streamline the transfer of ingredients from the factory all the way through the distribution chain where that particular product is put onto market. The reason why Goldratt came up with this method was because projects often got delayed, there were increases in costs during the project and the deliverables were often less than first promised. Normal process of project planning, with a project team, what tasks to be accomplished, and what sequence, must be defined before the method becomes useful. The main principle with the CCPM is to strip off the risk of starting the project late or finish it early, and instead put some extra time into a buffer.
