Marris Consulting, a company focused on improving 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 especially for New Product Development portfolios. We sometimes combine this with Lean Engineering (a.k.a Toyota New Product Development System).
