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 of this short video, Bill gives his definition of the Logical Thinking Process.


Logical Thinking Process training June 2016 opening speech

Paris, June 2016, day 1 of the Logical Thinking Process training course hosted by Marris Consulting, Philip Marris welcomes the participants with a speech.

Philip’s speech is a mix of teasing and testimony as well as an analysis of the growing relevance of Theory of Constraints (ToC). Philip also explains how the Logical Thinking Process tools help focusing, the core idea of ToC. Finally he shares his thoughts about why the participants are in the room that day: it takes a peculiar mindset to go the Logical Thinking Process way, people do not attend this course by chance.

After more than 16 minutes, Bill Dettmer finally can welcome the participants too.

I was fortunate to attend on the host side to facilitate the 6-day course, also taking care about video and photos of the venue. If you want to see how the 6 days unfolded in fastforward (2 mn), >click here<

3-color system for Goal Trees

In this 5 minute excerpt from the Logical Thinking Process (LTP) Alumni reunion with Bill Dettmer, June 2016 in Paris, France, I explain my 3-color system for assessing the current reality with a Goal Tree.

The 3-color system is a visual management tool to assess the organization’s readyness to achieve its Goal and shows where to act in priority.

You’ll find several articles on this topic here on my blog, for instance:

June 2016 LTP Alumni Reunion

June 2016, right after the 6-day Logical Thinking Process (LTP) training course with Bill Dettmer in Paris, France, the first LTP Alumni Reunion took place.

The 2-day reunion’s intent was to bring together former LTP students who attended one of Bill Dettmer’s numerous courses, share experience and “war stories” and start building a community. Bill was also proposing a hands-on workshop to demonstrate how to build a Current Reality Tree with tighter logic using the syllogism.

I participated as an alumni (2015) as well as a host. The event was hosted in our (Marris Consulting’s) offices in downtown Paris

The reunion proved to be a success, although the participants were limited in numbers (seats were not limited) mostly because of personal agendas.

Listen to Bill Dettmer opening the reunion

One participant was not a “true” alumni as he did not (yet) take the LTP course, but came in as a “guest observer”. Nevertheless, Jean-Luc was familiar with the TOC Thinking Processes and had personal experience using them.

In this video I am discussing the learnings from this event with Bill on the very evening of the last day.

As decided during the reunion, we will keep on proposing periodical reunions, yearly probably for gathering in some place and every six months in between with a live webinar.

We also created a LTP Linkedin discussion group to have a common space for announcements, sharing and promoting LTP:

The future alumni reunions will be relatively open to newcomers upon invitation and the LTP group will remain open to non-alumni.

I hope to meet you somewhere in near future!

Discussing the Logical Thinking Process Alumni Reunion with Bill Dettmer

Immediately after the 6-day Logical Thinking Process (LTP) training course in Paris, France, June 2016, the LTP alumni of former training sessions gathered for 2 days in order to share experiences and hone our Logical Thinking abilities with Bill Dettmer.

Right after the second day of this reunion, I discussed the event with Bill in front of the camera:

Testimonies after the Logical Thinking Process training course – June 2016

June 1st to 8th, 2016 I was involved in the 6-day Logical Thinking Process training course with Bill Dettmer, in Paris, France.

I was part of the hosting party, did some organisation and promotion work, served as an assistant to Bill when participants went building their logical trees, shot pictures and videos of the event. During the last day I asked the participants if they would share their feedback in front of the camera.

Here are 3 of them: Max (Sweden), Nicolas (France) and Spyros (Cyprus)

Goal Tree chronicles – The mafia goal

During the June 2016 Logical Thinking Process alumni reunion, I shared some of my experience on building and using Goal Trees.

In the video excerpt here under I explain how I came across a probable hidden agenda leading to  what I call a “mafia goal”.

After listening to the story, Bill Dettmer gives his opinion about that.

Chatting with Bill Dettmer right after the Logical Thinking Process training, June 2016

This video chat was recorded the day after the second edition of the Logical Thinking Process (LTP) training in Paris, France was over, in June 2016.

I was fortunate to attend as part of the hosting organization, observer, facilitator, photographer and video director. The video setup was ready for the Bill Dettmer‘s LTP alumni reunion and I asked Bill to exchange our impressions about the course, in front of the cameras.

I attended the course as a participant one year before and as an observer kept impressed by the fast pace of the course, packing so much value in 6 days (2×3 with a week-end in between). This is only possible with the front loading (reading at least the selected chapters of Bill’s book) and having enough command of English for non-native speakers.

Watch Bill and myself exchanging more views on the venue.

Logical Thinking Process training course in Paris, June 2016 in fast flick

The second Logical Thinking Process (LTP) training course in Paris was a 6-day course in June 2016 delivered by Bill Dettmer. I was fortunate to attend as a host and observer, photographer and video director. Here is a 2-minute summary with pictures I took over the event. The speed of the video is intended to echo the fast pace and high density of the LTP course.

The Logical Thinking Process dynamics

In this short excerpt of the June 2015 training course, Bill Dettmer shows the links between the Logical Thinking Process tools.

The first link is from the Goal Tree to the Current Reality Tree (CRT). As long as the Goal is not achieved, the not-achieving Goal stated in the Goal Tree and the not-achieved Critical Success Factors (CSFs), which are Undesirable Effects, are inputs to the Current Reality Tree.

Next is the link between CRT and Evaporating Cloud (EC). A critical root cause from the CRT is very likely to be one of the conflicting entities of an Evaporating Cloud. The Goal Tree may also provide inputs to the EC.

An injection to dissolve the conflict in the EC is an input to the Future Reality Tree (FRT) and the desired outcome are the Goal and CSFs, turned into the FRT’s Desirable Effects, closing the loop and making the Goal Tree the key player of the whole Logical Thinking Process.
