This course is designed to provide you with the tools and strategies needed to achieve successful “Good Lean” outcomes and avoid the traps of Bad Lean.
"Today’s manufacturing systems have become more automated, data-driven, and sophisticated than ever before. Visit any modern shop floor and you’ll find a plethora of IT systems, HMIs, PLC data streams, machine controllers, engineering support, and other digital initiatives, all vying to improve manufacturing quality and efficiencies.
Philip Marris, a leading authority in the fields of Lean / Toyota Way and the Theory of Constraints (TOC) describes how and why he combines these 2 approaches. With decades of experience and a track record of success, Philip shares invaluable insights into the powerful synergy between the Toyota Way and TOC methodologies. He talks not only about production, but also [...] Critical Chain Project Management and the Logical Thinking Process or Toyota's long term development of partnerships with suppliers. [...] He illustrates how TOC's laser focus on identifying and eliminating constraints complements Lean's waste reduction efforts, resulting in accelerated performance improvements and sustainable growth.

The attendance is free of charge, based on registration. We are opening the 53rd online year-long Conference on the day of Eli’s birthday, 31 March 2026 at 18:00 Israeli time, with a get-together of TOC oldies to speak about their time with Eli, and Eli’s impact on their lives. It is “Eli and I” gathering. We invite you to join our gathering, and celebrate Eli’s life with us.
The VAT factory types are the Theory Of Constraints’ powerful classification system of the different kinds of industrial manufacturing systems, they determine how plants should be analyzed and how they should be managed. The VAT system was developed in the 1980s at the time of Creative Output when Eliyahu Goldratt and his team were selling a scheduling software system called OPT based on differentiating between bottlenecks and non-bottlenecks.
The letters represent visually the Bill Of Materials but where the flow is from bottom to top (the opposite of most representations of flow). The raw materials and purchased components are at the bottom and the Finished Goods are at the top. Products flow upwards. The V-Plant has very few ...
“Lean has failed.” That’s the bold statement James Womack—founder of the Lean Enterprise Institute and MIT researcher whose team introduced the term “lean” to the world—made at a conference where we both recently spoke. It’s a comment that’s stuck with me. Has lean really failed? And, if so, what can we do to course correct? To explore his statement I invited James Womack to Chain of Learning, to share his reflections and experiences over the past 40 years—where his vision for lean management has fallen short, where it’s succeeded, and what we can learn for the future.

I am often asked to tell my story of how I increased the performance of a 1,000 person factory in only 15 minutes. The factory was located in the middle of Mexico. It produced alternators for the…
Philip Marris curates 5 different permanent news websites: 1) (This one) TLS - TOC + Lean + Six Sigma 2) Theory of Constraints 3) Critical Chain Project Management 4) Théorie des Contraintes (in French) 5) Chaîne Critique (in French)
This Introduction to Manufacturing focuses students on the issues that matter to practicing industrial engineers and managers. It offers a systems perspective on designing, managing, and improving manufacturing operations. On each topic, it covers the key issues, with pointers on where to dig deeper.
Many projects fail due to unrealistic promises, multitasking overload, and poor workflow management. [...] To address these issues, we propose a three-level control system. - Portfolio management ensures the system is not overwhelmed with too many projects. - Critical Chain Project Management eliminates excessive safety margins by using a shared buffer, improving predictability. - Execution management uses Kanban and Agile techniques for efficiency. ...
TOC in Production Online Course extract: The 5 Focusing Steps. A Marris Consulting online service.
This course, that we launched one year ago, has been a great success. We continue to add to it continuously by enriching the appendices with more and more recent examples drawn from our unique experience of implementing the Theory Of Constraints in over 350 organisations throughout the world.
In the latest issue of The Management Brief, Jeffrey Liker urges the lean community to move beyond tools and templates—because lean is a way of thinking. Lasting transformation requires integrating lean’s technical, social, and scientific dimensions while developing people who can learn their way forward.
Philip Marris delivers a "Crash Course on the Theory of Constraints". The manufacturing analogy makes it easier for beginners to grasp the notions of bottleneck, buffer protection, Throughput... before transposing it to Project Management.
This thoroughly revised guide offers the current and next generation of supply chain professionals a clear explanation of the fundamentals of planning and MRP systems in today’s volatile and complex supply chains. Long considered the industry standard, Orlicky's Material Requirements Planning is an indispensable tool for manufacturing practitioners and candidates preparing for certification exams including CPIM, CSCP, DDPP and MRPFP.

Let's cut to the chase - in quality the real signal is in the noise; the real signal is in the noise. How could it be any other way? I can assure you that there is both a deep irony here and more than a little apparent contradiction.
In this video, Philip Marris presents the different components developed by Eliyahu Goldratt.
Eliyahu Goldratt is best known for his novel The Goal, explaining the basics of the Theory of Constraints (TOC) applied to operations. However, his work covers a lot of other topics. Some of them are related to constraints and bottlenecks in several fields of expertise. Eliyahu Goldratt also wanted to "teach the World to think", this is also known as the Logical Thinking Process. As this last part does not deal with constraints, Philip Marris separates the "Theory of Constraints" from "Logical Thinking", both of them being part of "Goldrattism".
Within the quality profession, a capable process is one with a high Cpk. In the field, process capability is not quite so simple. [...] “Many manufacturers that I know struggle with incapable processes. Intellectually, people understand the concept of capability, but are unable to effectively apply it to an entire process. A single-figure measure for the entire chain would be ideal to better understand and manage it. The challenge is that the chain consists of processes with measurable characteristics, like thickness, substitute characteristics, like leak current to infer dryness, and also visual inspection results like blemishes or scratches. ...
Eli Schragenheim, dedicated to making Theory of Constraints (#TOC) solutions accessible to SMEs all over the world, explains two big elements that he misses in the vast majority of ERP systems. With rare exceptions, a manufacturer who can't handle the following challenges must be inherently fragile, agree? 1. WHAT TO PROMISE - what can we promise our clients with a good chance of meeting all commitments? 2. HOW TO DELIVER WHAT WAS PROMISED - once we have committed to a client, how can we ensure fulfilling the delivery on time and in full? Inability to address these challenges creates a fundamental gap in the vast majority of ERPs. No wonder ERPs fail to yield the full expected value and return on investment.
