TRIZ, (pronounced [triz]), is a Russian acronym for "Teoriya Resheniya Izobretatelskikh Zadatch" (Теория решения изобретательских задач), a Theory of solving inventive problems or Theory of inventive problems solving (TIPS) (less known as Theory of Solving Inventors' Problems), developed by Genrich Altshuller and his colleagues since 1946.
TRIZ is a methodology, tool set, knowledge base, and model-based technology for generating innovative ideas and solutions for problem solving. TRIZ expands approaches developed in systems engineering and provides tools and systemic methods for use in problem formulation, system analysis, failure analysis, and patterns of system evolution (both 'as-is' and 'could be'). TRIZ, in contrast to techniques such as brainstorming (which is based on random idea generation), aims to create an algorithmic approach to the invention of new systems, and the refinement of old systems.
