The Director of Circor Aerospace testifies of the results obtained thanks to the Critical Chain

Implementation of Critical Chain Project Management at Circor


The Plessis-Trévise site has implemented the Critical Chain Project Management and has obtained excellent results, particularly in terms of time savings and meeting deadlines.


Frédéric Grehal, General Manager at Circor Aerospace & Defense, explains how the support of Marris Consulting has helped to set up the Critical Chain and the benefits generated. During the Covid-19 health crisis, many projects were delayed.

Using Critical Chain Project Management to manage projects has therefore become obvious. Implementing this method involves meeting many challenges: aligning all employees, investing the time, means and resources necessary.


Marris Consulting teams are involved in all stages of deployment. First of all, there is a methodological support with a whole component of pedagogy and training. Then, there is the concrete implementation of the method on starting projects, with the coaching of the teams and a follow-up of any drifts and potential delays.


The Critical Chain enables significant improvements: meeting deadlines, anticipating problems, increasing team motivation, etc.

The difficulty then consists in perpetuating the use of this method. This requires the integration of the concepts at all levels of the company: training, integration, recruitment and within the processes.
