The Logical Thinking Process

Online course


You are a manager and you have to answer questions such as "What to change? What to change to? and How to cause the change?"

You need to overcome resistance to change and find beneficial solutions.

To do so, you need to gather the insight of your colleagues and communicate your ideas.

The Logical Thinking Process is nothing less than a broadly applicable, systems-level approach to policy analysis. The LTP will help you develop and implement solutions successfully.

We created this website to offer you everything you need to learn on the process to construct the logic trees of the Logical Thinking Process while simultaneously ensuring that the results are more logically sound and closer representations of reality.

Welcome!

A word from the trainers

The Logical Thinking Process (LTP) training is now available ON-LINE.

These training workshops have been in the past face-to-face events. Wishing to make these training courses accessible to a wider audience, we reformatted the LTP workshop into an online course.

We are excited to embark on this new journey!

Strategic Thinking

Strategy & the Logical Thinking Process

In 2001, the 9/11 attacks created an instant paradigm shift for the commercial airline industry. In 2020, the SARS-CoV-2 virus, better known as COVID-19, wrought a similar impact on societies worldwide. In both cases, businesses and governments struggled with the wide-ranging effects and the precipitous onset of bureaucratic attempts to counter or mitigate them. There’s no need to recount the sordid history of both cases. Even today, 50 percent of the businesses that closed their doors during the COVID pandemic have not reopened.

But consider this: Could the airlines have fared differently if, early on, they had treated the terrorist hijackings as a quantum shift in their external environment and immediately set about creating new strategies for succeeding in a now-hostile business environment? Could governments have better weathered the COVID-19 storm and done less damage to their societies with a carefully considered strategy for dealing with the pandemic?

The lesson of both these examples is that a well-developed strategy was lacking in both cases. In fact, it’s probably safe to assume that nobody even thought about creating a strategy at that point. There are two possible reasons for this. First, each case was a chaotic emergency that drew everyone’s attention to current events of the time. Nobody even thought about strategy while the house seemed to be burning down. Second, everybody who could even spell “strategy” had a concept of it as abstract, requiring much time and effort to develop and too unresponsive to the need at hand.

Nothing could be farther from the truth. Yes, people, especially leaders, made those assumptions. And they were wrong. As I’ve pointed out in two of my books, Strategic Navigation: A Systems Approach to Strategy Development and Deployment and The Logical Thinking Process: A Systems Approach to Complex Problem Solving, strategy need not be either ponderous or unresponsive to radical changes in the external environment. The Logical Thinking Process is equally effective in strategy development and problem-solving.

How about your situation? In this post-COVID world, doesn’t worldwide inflation pose an equally dramatic paradigm shift? What about the increasing threat of international war? Wouldn’t you think that most commercial for-profit and government organisations could benefit from creating a coherent direction for themselves over the next several years (not to mention a way to get to their goal)?

If there were any time for a robust, flexible approach to strategy creation and deployment, that time is undoubtedly now. Sure, the environment is constantly changing. All the more important is that such an approach can “turn on a dime,” revamping rapidly to accommodate emerging events. The Logical Thinking Process is probably the most effective, proven way of doing that. Whatever your professional speciality or your position in your organisation, your future work will likely involve — maybe ever require — strategic thinking and the ability to regroup and redirect quickly. So, what are you waiting for? Time’s wasting. Get busy and start learning the Logical Thinking Process. The livelihoods you save may include your own!

Frequently asked questions

You’ve got questions. We’ve got answers.

Is it possible to buy the videos only?

Yes, select the offer "videos only". You will have access to the full course but you won't benefit from our coaching sessions. 
Online courses are great because unlike in the face-to-face workshops, 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 as much as they want.

Is it possible to reschedule a session with our coaches?

Yes, Calendly allows you to do that.

What are the required readings?

Reading the appropriate chapters in the book The Logical Thinking Process, A systems approach to complex problem solving before commencing the videos and practice on each of the logic trees is strongly encouraged. We believe that this will significantly contribute to your success in learning and applying the LTP in real-world circumstances.  


The book is available as an e-book.
You can also read the Executive Summary of the book.

Do we earn a certificate?

Yes, successfully completing the fully facilitated LTP course (including instructor interaction) earns a Certificate of Mastery. To do so, the little "complete" box on the right bottom corner on each lesson must be ticked.
Watching the video presentation alone earns a Certificate of Completion.

What tools exist to build the trees?

There are many tools. We recommend Lucid Chart. There are others like:
paper and pen, Flying Logic, Microsoft Visio, Mural, Miro, etc.

Where can I find my invoices?

Here is how you can quickly access all your invoices: click on your profile (on the top right corner), click on "settings", scroll down to the "Billing" section and finally click on the "view" button next to "Invoices".
