ABSTRACT
In this part of the book, operations that have to be fulfilled to solve a problem correctly and successfully are listed and described in detail. This list has a linear structure, but the real problem-solving process is straight along the line only if the facilitator knows how to solve it, but stakeholders do not (e.g., teacher and pupils in the school). But if the problem is complex for the facilitator as well, then the trajectory of solving it acquires feedback loops (for obtaining additional information). Moreover, the more complicated is the problem, the more such loops are needed (the method of trials and errors).
