Theory of Constraints, Critical Chain Project Management, Lean : industry consulting & training - Marris Consulting
Today, many industrial companies are considering the reorganization of their workshops, the relocation of equipment, or significant investments aimed at expanding capacity and reinforcing operational capabilities.
Whether the project involves a full redesign, the deployment of a new production line, or the transfer of assets from one site to another, such transformations require disciplined planning and precise execution.
These initiatives often involve major constraints: moving heavy machinery, coordinating infrastructure works, aligning internal and external stakeholders, and, in some cases, securing the required qualifications and certifications — all under highly compressed timelines.
In many situations, every hour matters, as interventions on production facilities frequently require production to be stopped or disrupted.
So what are the key success factors to finish such Capex projects quickly and on time?

To address these constraints, manufacturers need a proven way to reduce project timelines, ensure the reliability of key stages, and limit deviations that could generate significant unplanned costs.
The goal is no longer simply to complete the project, but to manage it with speed, control, and punctuality, respecting the scheduled completion date.
It is with this in mind that Marris Consulting supports industrial sites facing this type of challenge, notably by leveraging Critical Chain Project Management. Derived from the Theory of Constraints, this approach strengthens execution reliability and significantly reduces downtime.
During this webinar, Philip Marris explains how Marris Consulting deploys this method several times a year all over the world. He presents the two discinct phases: the preparation and then the execution phases of such investment projects.
The presentation combines the fundamental principles of the Theory of Constraints and the Critical Chain with feedback from assignments carried out in different sectors, including aeronautical parts manufacturing, chemical industries, medical devices and pharmaceutical production and logistics warehouses.
Philip started his Theory Of Constraints journey in 1986 when he joined Creative Output and worked with Eliyahu Goldratt, the founder of TOC and author of the worldwide bestseller “The Goal”. In 1994 he wrote a bestselling TOC textbook in French.
