A Good Strategy & Tactic Tree


Jelena Fedurko

The book is a detailed guide to help understand and construct the most comprehensive logical tool – the Strategy and Tactic (S&T) Tree.

A Good Strategy & Tactic Tree is a rigorous textbook that presents rules, examples, and exercises in the four areas of constructing an S&T Tree:

  •  the content of the entities in the S&T boxes;
  •  the relationship between the entities within the same box;
  •  the vertical relationship between the S&T boxes;
  •  the S&T structure.

In her new book, Jelena shares her recent developments in the area of working with major TOC logical tools. Jelena’s books are an important contribution to the TOC body of knowledge.

What readers say about Jelena’s books:

Every so often a book comes along that fills a gap, that makes us say, “That’s just what I was looking for.” Many of us in the TOC community consider the cloud to be our most powerful and most frequently used TP tool. We users will appreciate the careful attention Jelena Fedurko has given to our favorite construct, the cloud. Her knowledge of this tool, and her understanding of the logic behind it, are clearly expressed in these pages. The ample examples and detailed explanations make this unquestionably the most powerful book on clouds yet written. She has upgraded all of our knowledge, and provided a permanent addition to the TOC body of knowledge. We are all in her debt. If you are serious about TOC, you must own this book. – Forward to Behind the Cloud by Dr. Alan Leader

Your book [Behind the Cloud] has been a perfect support for me to dig further into the Cloud’s mechanisms, and its relationship with the other TP tools.

I’m quite a TOC newcomer, but already a big fan. I’m getting into Clouds and I heard very good feebdacks about your book.

I have read your book Behind The Cloud and enjoyed it very much. I learned many new ideas.  Thank you.

We recently acquired the book “Behind the Cloud” by Jelena Fedurko. An excellent guide to raising assumptions in a cloud!

I am one of the guys that I watched your presentation back in Germany about the UDE clouds and I also bought your new book [Through Clouds to Solutions]. I just wanted you to know that I found your book to be just great !!! you did an excellent job setting it up for all the rest of us. I found it extremely useful – I have read it 10 times and I advise it all the time. It is really excellent !!

I just wanted to thank you for your well written book [Mistakes and Difficulties in Working with TOC Logical Tools]. This is a great read for anyone wanting to REALLY understand clouds and CRTs.

Your previous books have been so good, I look forward to receiving your S&T Book.

All of your books are excellent.  Clean, clear, quick, no-nonsense teaching material.

I have begun using “Through Clouds To Solutions” to properly frame UDEs (reference 10 Rules) – & intend using it extensively to make the UDE clouds and then onwards to the core conflict & CRT, using the Three Cloud Method. This is to acknowledge that your work has been a ‘big big help’ – difficult to imagine how I would have managed it without your explanations,  error examples & workbook exercises… I feel sorry for the many TOC practitioners who are wanting to master the use of  cloud technique but are either unaware or not fully connected to your work, for whatever reasons – pity that they are not benefiting from your immense contribution in this area…..!!

Your book [Mistakes and Difficulties in Working with TOC Logical Tools] arrived last night it is fantastic!!! I have not stopped reading it.
