What is Critical Chain Project Management?

The Critical Chain Project Management (CCPM) paradigm represents a project management approach developed by ecologist Eliyahu M. Goldratt in the 1990s, and it is based on the Theory of Constraints (TOC). This goal involves rationalizing inputs and reducing the expected adverse effects of uncertainties and variabilities....

The History of Critical Chain Project Management

Publication of “Critical Chain”: In 1997, Goldratt published his bestseller which was the “Critical Chain” and in 1999 he wrote “The Oxford Guide to Project Management” and thus introduced, for the first time to the world, the term CCPM. This book explained in pages how CCPM was designed in its basic principles, such as critical chain, buffer management, and of course efficient resource utilization. Development of Software Tools: The result of the spread of this novel was successive lines of developers who made softer corporate-intensive programs in support of CCPM. Such a solution had functionality for a calendar, resource management, buffers administration, and status analytics facilitating the implementation of CCPM architecture in the businesses. Integration with Lean and Agile Practices: In contrast, over time the CCPM methodology was combined with other management methods, such as Lean and Agile, that helped to better adapt to the different contexts. This integration model established the birth of agile blends that combine principles of CCPM and lean manufacturing and Agile software. Case Studies and Success Stories: When companies began deploying CCPM several practice examples and success stories appeared, showing the excellent results of CCPM for performance. With these real-world examples on hand, the use of CCPM to support organizations was further validated, and others were eager to adopt it. Continued Research and Development: This approach has been a work in progress, as the change of dynamic systems such as the global economy through research and development. During the recent years people behind CCPM have investigated new uses of the technique, improved its practices and insisted on methods of implementing CCPM in other businesses and environments....

The Components of a Critical Chain

Critical Tasks: The constraints of these tasks can constrain the vital path, which is the path with the greatest likelihood of enduring the project’s total duration. Jobs like this allow no comfort zone and have no float or slack which implies any slight delay will negatively affect the project progress. Resource Dependencies: A critical chain is tailored to resource dependencies, and therefore, task durations differ due to two reasons: their inherent duration and the availability of required resources for completion. From the point of the resources, that are available on a critical chain, are what will determine the entire project timeframe. Resource Buffers: Critical tasks may be covered by resource buffers, which in turn may be included in the critical chain to avoid schedule slacks due to resource scarcity or lack of resource visibility. These buffers, among others, have assigned sensitive jobs to have an allowance to stay within the resource fluctuations without affecting the project’s chronology. Resource Buffers: Critical tasks may be covered by resource buffers, which in turn may be included in the critical chain to avoid schedule slacks due to resource scarcity or lack of resource visibility. These buffers, among others, have assigned sensitive jobs to have an allowance to stay within the resource fluctuations without affecting the project’s chronology. Project Buffer: The buffer is located after the critical chain schedules the critical path task, to overcome potential delays in their completion. It stands for part of the total project duration after it is applied to the entire project to allow consideration of uncertainties and variations in time which specific events may take on the critical chain. Buffer Management: Careful planning of the buffers is one of the key features of the CCPM methodology. Project managers, throughout the process, monitor how buffers are consumed and used in the project. Thus, avoid the use of excessive buffers which protect against delays to avoid unnecessary padding of task durations. Dynamic Resource Allocation: Plan replication of resources across the critical tasks within the critical path to guarantee their due-time delivery. Efforts are undertaken to mitigate the impacts of resource limitation by ensuring that resources aren’t overused and that there’s proper resource utilization....

Conclusion: Critical Chain Project Management (CCPM)

With CCPM the task in project management is organized systematically, from the planning stage until the implementation of projects. This is done in the light of resource optimization and buffer management. Through employing CCPM measures, organizations can manage risks, reduce aspiration and, therefore, increase opportunities for project success....
