Strategy course and "Logical thinking Process" by Bill Dettmer

Logical Thinking Process 6-Day course - online


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.

This training course was initially, until 2019, proposed in a 6-day format in our Paris offices. Because of the Covid-19 pandemic, we are currently setting up an online version of the same training with Bill Dettmer.

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.

Two short videos 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? 

Learning objectives :

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


Message from Bill Dettmer

NEW! The Logical Thinking Process (LTP) training will soon be offered ONLINE

These training workshops have been in the past unique, hands-on, face-to-face events. And having the privilege of conducting them in Paris for many years now has been really special. But the pandemic has squashed for now the unique benefit of a face-to-face gathering with people coming from all over the world.

Many people have asked me whether the LTP training would be offered online. And I’ve had to say, “Not for the foreseeable future.” But now that is about to change.

In concert with my partners Marris Consulting, I’m engaged in reformatting the LTP workshop into an online course. Now, this course will never be able to completely match the group dynamic of an in-person workshop. But I believe that if the effective transfer of LTP knowledge is preserved as the overriding objective, that goal is reachable. However, in doing so, considerably more personal responsibility for learning and practicing must necessarily fall on the LTP training participant.

The objective remains the same: to teach you how to use the Logical Thinking Process by helping you to solve a systemic problem of your choosing. It is a workshop.

As we conceive it now, the online LTP course will be composed of four parts:

  1. Advance reading, by the participant, of the course textbook, “The Logical Thinking Process: A Systems Approach to Continuous Improvement.” The whole book need not be read in advance, unlike with the in-person workshops. Instead, participants can read the appropriate chapters just before completing the online visual presentation by me of that chapter.
  2. The online presentations will be available on demand. Participants can decide when they want to go through the visual presentation—night or day, weekdays or weekends. And they will be able to advance through the slides, back up and see a particular slide again (and hear the narration that goes with it), and, if they like, repeat the entire presentation a second or third time during the course.
  3. Personal review of the presentation material. With me. Once a particular presentation is done (and there are eight of them all together), a Zoom or other interactive video call will be arranged, so that each individual participant can ask questions about the presented material and have me explain any uncertainties to their satisfaction. These sessions would likely last an hour or so.
  4. Practical experience constructing LTP logic trees. This is where individual responsibility and persistence is most important. After the block of instruction on each logic tree (steps 1, 2 and 3, above), participants will commence constructing a logic tree on their own. As in the face-to-face workshops, these trees will be built to address a systemic problem of the participant’s own choosing. The individual learner will be able to use both manual pen and Post it notes and a software program designed to render logic trees.
  5. Personalized logic tree review and scrutiny. Once participants have completed construction of each logic tree on their own, I will schedule another online meeting with each participant. They will present their logic trees to me, one per session, until all five logic trees have been covered. I will offer constructive advice and reinforce the rules of logic in their tree construction. These sessions may require more than an hour to complete.

A face-to-face LTP workshop—the only kind I have ever conducted before this—normally requires six intensive days to complete. This has the advantage of completing the entire course in no more than about a week. But the kind of online training we’re going to introduce must necessarily cover all the same material in much smaller “bites,” separated by delays for the completion of the supporting activities in a piecemeal fashion. This is the aspect that participants are likely to find more challenging.

When you’re in a dedicated six-day workshop, you have no outside distractions, and the pace is set by someone else (me). When it’s up to you to set the pace of multiple online sessions, distractions can seductively creep in, and you must set your own pace. This necessarily extends the entire LTP course well past six days. The tradeoff is that you realize the flexibility of setting your own pace. The price for that flexibility is the responsibility and self-discipline of keeping yourself moving forward at the most expeditious pace you can until the online course is done.
The LTP course will be partitioned into two major parts: the reading and learning presentations, and the practical experience in building trees. Each part will be contracted separately. So, participants will have the flexibility of completing ONLY the first part under my supervision and doing the practical tree building part, on their own and at their own pace, without my involvement. Or, they can complete BOTH parts under my supervision.

More information will follow on things such as video conference software, logic tree software, books, supplementary materials, pricing and other particulars.

We hope to offer the first sessions in the Summer of 2022.
