Critical Chain in Aeronautical Maintenance (MRO)
Critical Chain applied to aeronautical maintenance
Critical Chain is now widely used in aeronautical maintenance (MRO or Maintenance, Repair and Overhaul / Operations). The United States Air Force, the largest fleet of aircraft in the world, is in the process of a global rollout and several airlines have adopted it throughout the world.
In this video we start by presenting the list of the over 30 aeronautical MRO cases worldwide from the USA to Australia and from Brazil to France.
We then discuss why the fact that it is quite easy to calculate the cost of winning or losing a day in the hangar has meant that this industry is leading the world in the adoption of Critical Chain Project Management (CCPM). In this business they know that gaining an extra day in their Turn Around Time is worth often of the order of $100K. They know better than anyone that time is money (or mission critical for military aircraft).
CCPM and its proven results is therefore the obvious solution. We share the lessons learnt these past 20 years. How the starting point is often that there are too many aircraft being worked on simultaneously (not enough focus).
- Why the planning and scheduling competencies must often be reinforced. How CCPM brings (as usual) exceptional visibility on the progress of each aircraft.
- Why the availability of the spare parts is (of course) a necessary condition for success.
- Why using “Work Packages” and 2-tier scheduling facilitates the management of the execution and avoids falling into the trap of micro-management.
- How the identification of “findings” (unplanned extra work due unexpected deteriorations) become even more critical (because everything else is going much more smoothly).
- How, as a result, visits are often cut into 2 stages; a first stage where you do whatever disassembly and tests are required to identify any “findings” and a second stage where you do the work.
- The differences when dealing with recent aircraft versus old aircraft.
- The limits of CCPM in aeronautical MRO (when the visits are too short and simple to require fully fledged project management).
- Etc.
We also mentioned several “common sense” solutions that become even more important when travelling at CCPM speeds such as ensuring that the mechanics always have a “full kit” to do their job (the parts, the tools and the documentation).

Philip Marris, founder and CEO
Philip Marris started his Theory Of Constraints (TOC) journey in 1986 when he started working with Eliyahu Goldratt. He founded Marris Consulting in 2003. The companies’ assignments are nearly always TOC based. He has implemented TOC over 270 times in over 25 different countries over the past 30 years. He has for instance assisted: Siemens, GSK, Safran and Ariane rockets. Half of Marris Consulting’s assignments are Critical Chain implementations.
He is the author of a bestselling TOC textbook in French. He is bilingual and bi-cultural French/English and lives in Paris, France. Marris Consulting has extensive aeronautical MRO experience: Embraer, Air France, ABS Jets, Dassault,… A 30-minute dive into Critical Chain in aeronautical maintenance (MRO).

Marris Consulting, expert in Theory of Constraints & Critical Chain Project Management
Marris Consulting is an expert in the Theory of Constraints (ToC) and Critical Chain Project Management (CCPM). As industry consultants, we are focused on helping process and manufacturing industries reach their highest levels of performance by using Constraints Management combined with Lean and Six Sigma. We also use Critical Chain Project Management which we sometimes combine with Lean engineering to improve project performance. If you are unsure about the actions which need to be implemented to improve operational efficiency, our industrial management consultants can also conduct a performance audit. Furthermore, our experts host numerous Theory of Constraints (ToC), lean and project management training sessions throughout the year.
