Classical TRIZ and OTSM as a scientific theoretical background for non- typical problem solving instruments

This paper presents the structure of Classical TRIZ (the Theory of Inventive Problem Solving created by Genrich Altshuller) and OTSM (the Russian acronym for the General Theory of Powerful Thinking, proposed by Altshuller in several papers and letters to the Russian TRIZ community between 1975 and 1986). In brief, the model comprises a key problem to be solved by the theory and the assumptions established to solve it. A set of fundamental models based on these assumptions was developed as the theory evolved. Practical instruments were then developed on the basis of these models (i.e. within the framework of the original assumptions). The System of Instruments was also used to evaluate the theory and develop it further. The model of an applied scientific theory was used to study TRIZ and develop OTSM.
