Logical Thinking Process


Online training course designed by world expert Bill Dettmer


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


The 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. Due to the Covid-19 pandemic, a 100% online version of this training course was created. It is available, at the following address:

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.

Client testimony


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?
