Logical Thinking Process 6-Day course

From 9th to 16th June 2021 in Paris

Craft an actionable future and bring your organization to a higher level


Logical Thinking Process, as the name suggests, uses sound logic and a set of tools or processes to provide executives and system managers an effective method for designing organizational strategy, planning its deployment, evaluating its effectiveness, and making corrections as needed in the shortest possible time.

Couverture du livre The Logical Thinking Process de Dettmer


The LTP can typically produce a completed strategy within a matter of weeks, including the required deployment tasks and activities. It provides an easy way for executives to monitor progress of strategy deployment. In the problem-solving mode, resolution of complex system problems has been designed in as short as a few days and no more than several weeks (the time required for solution implementation varies with the nature of the situation).

The two most significant challenges leaders and senior managers face are creating and deploying an effective organizational strategy and solving complex system problems.

  • Where do we stand today?
  • What will be needed for tomorrow?
  • What is holding us back from achieving new levels of success?
  • What should we do about it?
  • How can we change direction?

These are all questions that traditional methods of continuous improvement are ill-equipped to address. Strategy development and complex problem solving represent opposite sides of the same coin.

Consider that problem solving at the strategic system level is no more than identifying the shortfalls in performance against the originally designed strategy, determining the reasons why these gaps exist, and creating ways to close them—thus improving the success of the original strategy.

Watch this short video of Bill Dettmer explaining what are the LTP and the benefits you can get from the training course

The Logical Thinking Process (LTP) is an integrated set of logic trees intended specifically to answer four essential questions crucial for both strategy development and problem solving:

1. What is the benchmark of desired system performance?
2. Why is the system not already achieving that benchmark?
3. What should be done differently to achieve the benchmark?
4. How should changes be effected? 


By the end of this training course, participants will be able to:

  • Be self sufficient to read, construct and review Goal Trees, Current Reality Trees, Conflict Resolution Diagrams (Evaporating Clouds), Future Reality Trees and Prerequisite Trees

  • Surface and identify root causes of complex problems and build robust solutions to solve them

  • Assess and mitigate the risks of the proposed solutions

  • Apprehend the difficulties about change and settle conflicting objectives

  • Identify and overcome possible obstacles

  • Build a straightforward plan for change and present an executive summary

The process is front-end loaded: participants are strongly advised to read the provided book beforehand, in order to complete this strategy course in 6 days. Participants bring a real-world problem to be solved of their own in order to apply learning to a familiar case.

The course begins at 9:00 and ends at 18:00 every day, except the last day which is shorter to allow travelling back home. Course is in English language, however some explanations can be given in French (no full translation).


Day One

  •  Introduction
  •  Logical Thinking Tools overview
  •  Goal Tree: how to establish benchmarks, hands-on constructing participant’s Goal Tree
  •  Categories of Legitimate Reservation: critical review of the Goal Tree’s robustness

Day Two

  •  Current Reality Tree: compare the “as is” situation against Goal Tree, the desired situation
  •  Conflict Resolution Diagram (Evaporating Cloud)

Day Three

  • Conflict Resolution Diagram (Evaporating Cloud)


  • Week-end break
  • The week-end in between is purposely set to give participant a rest as well as time to reflect and transpose their learning in their own case

Day Four

  • Future Reality Tree and Negative Branches: closing the gap between current situation and desired situation and mitigating risks

Day Five

  • Prerequisite Tree: how to solve the problems and go from Current to Future
  • Reality with concrete actions

Day Six

  •  Change management
  •  How to build Executive Summary Trees
  •  How Thinking Processes can help solving complex problems

Lunches are included.
