Welcome to the Marris Consulting website, a company focused on improving significantly and sustainably the performance of manufacturing and process industries

We have over 25 years of experience of combining the Theory of Constraints (ToC) with Lean to go faster and further: 1 + 1 = 3

We help our clients 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 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" is the founder and CEO of Marris Consulting.

Our motto: Factories, People & Results.
