Unified Structured Inventive Thinking: How to Invent by E. N. Sickafus is a very complete textbook for the USIT method, derived from TRIZ. Ed Sickafus is an inventor and industrial scientist at Ford Motor Co., and a teacher and practitioner of the USIT method.
The book's introduction gives a short history of SIT and USIT, tracing it from the work of Genadi Filkovsky to the work of Roni Horowitz and Yacob Goldenberg at the Open University of Israel to the work of Sickafus, Craig Stephan, and their students and colleagues at Ford.
The descriptions of the USIT methods are clear, and the examples are easy to understand. Many of the techniques are similar to those of TRIZ, such as formulation of a jargon-free description of the problem, and identification of the zones of conflict of the problem (called "Collection of Information" in USIT.) The "closed world diagram" in USIT corresponds to the functional analysis diagram or table, but also corresponds well with the problem formulator diagram. The USIT technique called the "qualitative change graph" is a very explicit way of formulating contradictions, if there are any in the problem. Although the USIT methodology uses the contradictions differently from the methods used in TRIZ to remove physical or technical contradictions, this is a method that TRIZ practioners could use to make it easier to understand contradictions in their problems.

This review is from: Unified Structured Inventive Thinking: How to Invent (Hardcover)
I had hoped to find a resource explaining the fundamentals of SIT, and it appeared that Sickafus's book was the right one to get. Unfortunately I find the book very difficult to read and understand, mainly due to the author's complicated writing style, but also due to the hundreds of spelling errors. I had to look up "in praesenti" thinking it was just another spelling error. The fault lies both with the author and publisher for allowing what appears to be a rough draft to be published. Unfortunately the author and publisher are the same guy in this case.Page 392 contains this: "Particles are on and at both ends of the line from toast to information to indicate that they are interrogating the condition of the toast and sending out corresponding information". All I can say is "?". In total I would say that the author seems more accustomed to writing research papers to be read and reviewed by peers than writing "how-to" books for those just getting started.
