Presenting a Current Reality Tree, for you to scrutinize

In this video I invite you to follow my presentation of an existing (already built) Current Reality Tree (CRT) and check its logical soundness, what we call scrutinizing. Should you find any flaw of logic, you may share it whether in the comments of this blog or on my YouTube channel.

Why you cannot use tentative language in a logic tree

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

Reader question: Goal Tree vs. Current Reality Tree

Here is a reader's question: I have difficulty seeing the difference between the Goal Tree and the  Current Reality Tree (CRT). With these two trees we assess the process.

Scrutinizing and improving a Current Reality Tree (video tutorial)

In this video, I scrutinize and suggest improvements on a Current Reality Tree (CRT) found on the Internet. A logically sound CRT is key to convince audience about the robustness of the analysis and the reality of the causes to the trouble. If there is room for doubt or the logical has flaws, chances are … Continue reading Scrutinizing and improving a Current Reality Tree (video tutorial)

Beware of the Logical Thinking Process apparent simplicity

It is not different with the Logical Thinking Process. The Current Reality Tree is maybe one of the logic trees the most attractive to … Continue reading Beware of the Logical Thinking Process apparent simplicity

Bill … Continue reading What advice to people wanting to experience the Logical Thinking Process Training Course?

Limits of Logical Thinking Process

In this excerpt of day one from the 6-day Logical Thinking Process training course, Bill Dettmer explains that the very front end, the two first tools (Goal Tree and Current Reality Tree) are deterministic, based on facts. The other steps and tools are about future, which can only be based on probabilities. At the end … Continue reading Limits of Logical Thinking Process

Bill Dettmer refining some points about Logical Thinking Process

In this video, an excerpt of Bill Dettmer's Logical Thinking Process (LTP) training course in Paris, June 2015, Bill refines some points about LTP. First, the two first tools (Trees) of the LTP, namely the Goal Tree (GT) and Current Reality Tree (CRT) are based on facts. The others, Evaporating Cloud (EC), Future Reality Tree (FRT), … Continue reading Bill Dettmer refining some points about Logical Thinking Process

Rotate a Tree to start your project

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
