Welcome to the Marris Consulting website, an industry consulting and training company focused on significantly and sustainably improving the performance of manufacturing and process industries.
We have over 25 years of experience combining the Theory of Constraints (ToC) with Lean to go faster and further: 1 + 1 = 3
As project management and performance improvement consultants, We help our clients worldwide reach and maintain ambitious levels of performance by combining actions on processes, organization, methodologies, tools … and people from the shop floor to the board room.
We are recognized experts in Constraints Management. We promote an integrated approach that combines the Theory of Constraints (ToC) to identify where to act and Lean and Six Sigma to improve performance.
We also use ToC's Critical Chain Project Management (CCPM) approach to boost project performance. We sometimes combine this with Lean Engineering (a.k.a Toyota New Product and Process Development System).
Our Supply Chain projects usually involve Demand Driven MRP (DDMRP).
Philip Marris, author of the french book "Le Management par les contraintes" (Constraints Management) is the founder and CEO of Marris Consulting.

What is a Fever Chart? (Critical Chain Project Management) - 4 min. summary
Philip Marris, CEO at Marris Consulting, explains how you can monitor your project with a Fever Chart during the execution phase.
Marris Consulting is a recognized expert in Theory of Constraints consulting and training. The Theory of Constraints (ToC) is a productivity and operational efficiency improvement methodology which emphasizes the importance of identifying the primary limiting factor (i.e. the constraint, or bottleneck) that prevents companies reaching their goal. By leveraging this constraint, organizations can achieve their goal while gaining greater control over operations. Constraints management provides a powerful set of tools to improve manufacturing processes, including Throughput Accounting and the Logical Thinking Process or Thinking Processes. The implementation of the Theory of Constraints has yielded remarkable results for companies all around the world.
Lean, also called The Toyota Way, originated in Toyota Motor Company. It is multifaceted and includes cultural and managerial elements such as “respect for people”, an emphasis on improving flow, a relentless quest for perfect quality… To explain the confusion often associated with Lean, we refer to “Good Lean” and “Bad Lean”.
As experts in operational excellence consulting and training, Marris Consulting assists companies in all their major processes (manufacturing, project management, supply chain, marketing and sales…) and uses various approaches to provide sustainable solutions to help its clients achieve the highest levels of performance (Critical Chain Project Management, Lean Manufacturing, Lean Engineering, ToC + Lean + Six Sigma…).
If you have doubts about the improvement actions to implement, our manufacturing consultants can conduct a 2-day performance audit and provide you with detailed recommendations that can be implemented in the short, medium and long term.
Our industrial management consultants also host several training sessions throughout the year (ToC, Lean, Critical Chain Project Management, Logical Thinking Process and more).
