Five years ago, August 2015, I published my post “12 tips for leading in a downturn”. It was a collection of tips after having seen various management reactions to a slowdown, downturn, crisis, recession, that appeared in series from 2000 onwards. July 2020, France is officially out of its general lockdown and faces the aftermath … Continue reading 12 tips for leading in a downturn, COVID reloaded – Part 1/3
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
Paris June 28th, 2017. The 6-day Logical Thinking Process Training Course with Bill Dettmer is just over. We asked the participants not in a hurry to rush to an airport or train station if they would share their thoughts about the course in front of a camcorder? Cédric, Sverre and Leo were so kind. Bill … Continue reading What advice to people wanting to experience the Logical Thinking Process Training Course?
Did you experience this utmost frustration when having implemented a solution or countermeasure to a problem, a new issue arises brought up by this fix? This is what Negative Branch Reservation (NBR) intents to prevent. Negative Branch Reservation is a robustness test usually associated with a Future Reality Tree (FRT). It checks what could go … Continue reading What is Negative Branch Reservation?
During the Logical Thinking Process training course (June 2015), Bill Dettmer took us through the whole process and the associated tools at each step. The process starts with the famous Goal Tree, assess the current situation and focus on critical root causes with the Current Reality Tree (CRT). Conflict Resolution Diagram (AKA Evaporating Cloud) may … Continue reading Rotate a Tree to start your project
The Prerequisite Tree (PRT) is one of the Logical Thinking Process tools, mentioned among the Thinking Processes by the Theory of Constraints community. The Prerequisite Tree is used to surface and overcome obstacles to achieving the change towards the organization’s Goal by setting Intermediate Objectives (IOs). These IOs are sequential steps to implementing the change … Continue reading Thinking Processes – Prerequisite Tree
The Logical Thinking Process refers to the work of William (Bill) Dettmer summarized in the book of the same title. The Logical Thinking Process (LTP) is a one to six steps* integrated process using sound logic and a set of tools to provide executives and system managers an effective method for designing organizational strategy, planning … Continue reading Logical Thinking Process
I never liked the (Toyota inspired) Lean houses and their many variants. First all these models are generally understood as prescriptive rather than descriptive, thus those new to Lean tend to adopt and copy one model without necessarily understanding its real meaning. The building blocks of Lean houses are principles, methods and tools, reinforcing the … Continue reading Why I don’t like Lean houses, except one
A Future Reality Tree (FRT), as the name suggests is a visualization of a desired, improved future state. It answers the question "What to change?" Or "change to what?". The Future Reality Tree is one of the Thinking Processes or Thinking Process tools. A FRT usually follows an analysis with a Current Reality Tree (CRT) … Continue reading Thinking Processes – Future Reality Tree
The Current Reality Tree (CRT) is one of the Theory of Constraints (ToC) Thinking Processes (TP) tools. A CRT is built on Undesirable Effects (UDEs) linked by logical cause-effect-cause relationship called “sufficiency”. Sufficiency logic relationship is in the form of “if A is true then B is true”, or “if A exists, then B exists”. … Continue reading Bending the Current Reality Tree
