The TOC Innovation Summit 2026 brings together practitioners and leaders applying the Theory of Constraints to improve flow, focus, and outcomes in real organizations.
The best-seller “The Goal” by Eliyahu Goldratt described in the form of a novel how the Theory Of Constraints (TOC) could save a factory by quickly boosting its performance. But how exactly should one implement TOC (combined with Lean) in production? Philip Marris [...] presents the guiding principles: the 5 focusing steps. He presents 2 difference examples: one in the automotive industry and another in the aeronautics industry.
Most manufacturing executives recognize that value-based pricing is superior to the standard cost-based approach.
But because cost-based (or cost-plus) pricing is so firmly entrenched in organizational processes (and in executives’ minds), it’s almost impossible to migrate an established organization to this superior pricing approach during any reasonable timeframe.
To address this problem, here’s a carefully designed (and battle-tested) procedure that will enable your organization to transition to value-based pricing in five days flat.
To Never Run Out. Isn’t that “The Objective” everyone wants right now? [...] with Henry Fitzhugh Camp and Jake Lanning for the latest Episode of the Supply UnChained Podcast [...] They are now bringing to life their Material-as-a-Service concept called SupplyStream, which predicts the part demand, but also supplies the physical part at the right time. [...] We spoke about: -How a few $100Ms of pooled aircraft parts can unlock $50 BN+ of value for the airlines and aerospace primes, and cheaper airfares. [...] -How software alone does not solve the parts problem, [...] -How SupplyStream can serve almost any industry in the US -How they are maintaining 99.99% OTIF with their current set up -How tethering an MRP with Demand Forecasts or Consumptions is not enough, [...]

The Theory Of Constraints applied to process industries. Presented by Philip Marris and Etienne Lecerf.
In sectors such as metallurgy, steel-making, foundries, plastics processing, and chemicals, industrial flows are often based on a V-shaped model: a limited number of raw materials at the input stage and a wide diversity of finished products at the output stage.
In these highly capital-intensive environments, where capacity decisions are costly and resources are relatively inflexible, flow management becomes particularly complex, especially [...] MRP quickly show their limitations. [...] This rigidity often leads companies to produce in large batches, generating excess inventory, reduced agility, and operational tensions. [...] Drawing on Marris Consulting's experience of process industries, this presentation shares practical insights for better managing and optimizing flows in V-shaped plants ...
Clarke Ching — author of The Bottleneck Detective — joins Rory Sutherland and Elfried Samba to unpack why progress stalls, how leaders quietly become constraints, and why fixing the obvious problem often makes things worse.
Most organisations don’t fail because of a lack of effort. They fail because effort is applied in the wrong place. From traffic systems and hospitals to founders, governments and scaling teams, this conversation explores how bottlenecks hide in plain sight — and why seeing them requires a different kind of thinking.

Marris Consulting has reached 600 videos and 750,000 views it’s YouTube channel. The videos are mostly about the Theory Of Constraints, Critical Chain Project Management, and the Thinking Process. There are also many videos about Lean including a series with an ex-VP of Toyota Motor Manufacturing. Many tutorials. Dozens of conference recordings. Etc.
In this session, we’ll show you a new way to plan manufacturing using the Theory of Constraints (TOC) inside ERPNext, so you can move away from rigid rules, messy spreadsheets, and last-minute 1. A practical, TOC-inspired approach to production planning 2. How to manage manufacturing using flow, not forecasts 3. Live demo: Smart stock buffers & task priorities in ERPNext 4. How to eliminate delays, stockouts, and overproduction 5. Tools that replace spreadsheets and disconnected systems
The presentation and facilitated session describe the evolution of TOC from OPT, drum-buffer-rope (DBR), buffer management (BM), simplified drum-buffer-rope (SDBR) and make-to-availability (MTA) and reliable and rapid replenishment (RRR) strategy and tactics (S&T) tree. The assumptions of SDBR in make-to order (MTO) are provided. A MTA, MTO (MTA/MTS/RRR S&T) overview is provided.

AI is arguably one of the biggest paradigm shifts in the digital product development industry ever. Even if it stopped right now with Fable 5, we still would have changed so much that the before feel like a distant past.
Test your knowledge of The Theory of Constraints! Do you know the basics of the approach first described in the bestselling the novel "The Goal" by Eliyahu Goldratt? Take the test! 10 questions. With fully explained answers.
Philip Marris presented an overview of Critical Chain Project Management during the 38th TOCPA International conference in Paris. Critical Chain Project Management (CCPM) is the component of the Theory Of Constraints (TOC) that deals with project management; both single projects and project portfolios.
A brief 5 minute summary of how one applies the Theory of Constraints in a production environment. It covers: the axiom of the unbalanced plant, the existence of bottlenecks, the Drum – Buffer – Rope flow control mechanism and the improvement strategy (the 5 focusing steps). Philip Marris has been applying the Theory of Constraints and Lean in production for over 35 years (since 1986), over 400 times in over 35 countries.
For those working in manufacturing, capital projects, shutdowns or complex project environments, this is a chance to hear how TOC was applied in a real industrial setting. Come and hear their story : how they were asked by top management to take over this critical Capex project that everybody was very worried about using a project management approach that they had never heard of before.

A quick manufacturing riddle that reframes how you should think about scaling any business. Theory of constraints, business strategy, AI, entrepreneurship, systems thinking.
This is an extract from the 6-hour online course by Bill Dettmer on the Logical Thinking Process (of the Theory Of Constraints).
Stemming from the Theory of Constraints, the Logical Thinking Process consists of a structured way of reasoning and a set of tools or processes to help executives and system managers to design their organizational strategy, to plan its deployment, to evaluate its effectiveness, and to make corrections as needed in the shortest possible time.
Is 'TLS' – the integration or combination of TOC (T) with lean (L) and six sigma (S) – a good idea? What does it mean exactly? How do they reinforce each other? What are the incompatibilities? What are the case studies? Is it an opportunity or a threat for the TOC movement? Industrial improvement efforts over the past 20 years have been handicapped by quarrels concerning the relative merits of the different approaches and of the supposed incompatibilities or fundamental differences among them. TLS considers, on the contrary, that we should seek to combine them thereby creating a system that contains the best aspects of each movement. By Philip Marris
The long name of the Theory Of Constraints should be: the Theory Of Constraints and of the management of uncertainty. TOC has always included buffers to absorb uncertainty and variability. This is especially important in project Management (Critical Chain) where there is intrinsically a lot of uncertainty.
