Most companies, big or small, have a strategy, a plan for the coming year(s) with a set of high-level objectives and probably a Goal still to be achieved. Some of these plans are fairly elaborate, other less so and many are more intuitions expressed in broad lines and in rather informal mode. What executives often … Continue reading The benefits of fresh eyes on company’s strategy
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?
Paris, France, June 2018, during the Logical Thinking Process Training Course. Bill Dettmer asked me to lecture the attendees about the Goal Tree, the first of five logic tools of the Logical Thinking Process. I was happy to take over this part of the training given my love for the Goal Tree. However, the slides … Continue reading Me lecturing about the Goal Tree during the June 2018 Logical Thinking Process Training Course
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?
Bill Dettmer, my friend and mentor often cited on this blog, published his 9th book “The Logical Thinking Process - An Executive Summary”. This new book is much smaller in size and number of pages than the famous “big green book” (The Logical Thinking Process: A Systems Approach to Complex Problem Solving), only 65 pages compared … Continue reading The Logical Thinking Process – An Executive Summary (book presentation)
In Logical Thinking Process (LTP) parlance a long arrow is a “leap of logic” or the omission of one or several cause-and-effect steps that connect a cause to an effect. In the Logical Thinking Process, a cause is linked to its effect by an arrow. The arrow’s tail is connected to the cause and the … Continue reading What is a logical “long arrow”?
I once happen to see a Current Reality Tree cluttered with “coulds” and “shoulds”. Conditional or tentative language cannot be used with logic trees and here is why. Cause-and-effect (sufficiency logic) The Logical Thinking Process logic trees use either sufficiency or necessity logic. Sufficiency or cause-and-effect relationship states that a cause, if it exists, is … Continue reading Why you cannot use tentative language in a logic tree
Bill Dettmer, my friend and mentor often cited on this blog, wrote his 9th book “The Logical Thinking Process - An Executive Summary” that is now in the final stages of the publishing process. This book will be much smaller in size and number of pages than the famous “The Logical Thinking Process: A Systems … Continue reading The Logical Thinking Process – An Executive Summary (Book)
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
In this post I explain the difference between enablers and triggers in logic trees, which basically is explaining how Necessity logic differs from Sufficiency logic. I then explain the basic assumption when building a Goal Tree and why the Goal will not automatically be achieved even if a most of Necessary Conditions are fulfilled. Necessity … Continue reading Goal Tree Chronicles – Enablers vs.triggers
