TRIZ (pronounced “TREEZ”, the Russian acronym for the Theory of Inventive Problem Solving) is an established science, methodology, tools and knowledge- and model-based technology for stimulating and generating innovative ideas and solutions for problem solving. It is short for Teoriya Resheniya Izobreatatelskikh Zadatch.
Historically it has been widely spread in Eastern Europe, particularly in the countries of the former USSR and is a part of many university-, college-, school-education programmes.
TRIZ science expands system engineering approaches and provides powerful systemic methods and tools for problem formulation, system- and failure analysis, both as-is and could be (i.e., system patterns of evolution).
Original TRIZ was mostly applicable for analysis and innovative problem solving for manufacturing processes, e.g. process/product/performance improvement, failure correction etc.
TRIZ basic postulates, methods and tools, including training methodologies invented by H. Altshuller are now further developed and significantly enhanced by his followers, researchers and trainers.
