Two relatively similar ‘logical thinking ways’ exist and have almost the same names: the Logical Thinking Process and Theory of Constraints’ Thinking Processes. One may ask why two? and what differentiate one from another? The first in time were the Theory of Constraints’ Thinking Processes (TOC TPs, note the plural) that were initiated by Eli … Continue reading What differences between the Logical Thinking Process and Theory of Constraints’ Thinking Processes?
Who can better explain what the Logical Thinking Process is if not his father? Bill Dettmer worked with Eli Goldratt applying the Thinking Processes (subtlety about the plural) but spotted some weak points he managed to elegantly mend. He finally came up with an integrated process for solving complex problems at system level and refuses … Continue reading What is this thing called the Logical Thinking Process?
A system’s constraint, the limiting factor that is an obstacle to getting more Goal units* from the system, can be pretty difficult to identify (hence the success of my post on the topic: How to identify a constraint?!). *”Goal units” can be money, profit, services to citizens, number of patients treated, free meals served, or whatever … Continue reading Management attention as a constraint – Part 1/2
A Goal Tree is a logical structure linking the Goal of the organization to all subordinate Necessary Conditions (NCs) to achieve the Goal. The top most NCs are called Critical Success Factor (CSFs) in order to highlight their importance: they are the last things to achieve in order to achieve the Goal. These CSFs should … Continue reading Goal Tree Chronicles – Why You should NOT use a model
The definition of a constraint in Theory of Constraints (TOC) has varied as the corpus grew and matured. Still today it is confusing for newbies to sort out what is meant with "constraint", depending how they got their basics in TOC. Thanks to Eli Schragenheim, one of TOC's founding fathers, and the related post on … Continue reading Schragenheim’s concise history of constraints
It is one of the frustrations for Theory of Constraints (TOC) enthusiasts: why is their beloved business philosophy so barely known? No other, neither Lean nor Six Sigma had such a visible high-flying banner like “The Goal”, the (probably) first business novel*, sold over 6 million copies so far. If readers have been so many … Continue reading What keeps TOC confidential? (and me angry)
Things moved on since Eli Goldratt’s revealed Theory of Constraints through his business novel and bestseller “the Goal”. Most of today’s processes are more complex than 30 years ago: supply chains are stretched over the globe, new products are launched more frequently and batches are changed more often, among others. Thus identifying the bottleneck or … Continue reading You are probably wrong when identifying your bottleneck
I was fortunate to interview Eli Schragenheim, well-known expert of Theory of Constraints, during his visit in our offices in Paris, October 2015. This interview is about the 6 questions to challenge, question, test or frame any new development of technology, product or service. These 6 questions are: What value does it bring? What current … Continue reading 6 questions to frame your brilliant development idea
Startups are hype. I started asking myself how long known methodologies or management philosophies like Lean or Theory of Constraints can possibly help starting companies? When Eli Schragenheim visited our offices in Paris, France, in October 2015, I fetched the opportunity to ask him this question: How can Theory of Constraints help Startups? In this … Continue reading Eli Schragenheim on How can Theory of Constraints help Startups?
The Logical Thinking Process is the name of a book from Bill Dettmer as well as the name of a complex problem solving process inspired by Goldratt's Thinking Processes. Over time, while teaching the original Thinking Processes, Bill realized it can also be used for strategy deployment, not only complex problem solving. In this video … Continue reading The origins of Logical Thinking Process
