TRIZ (; ) is a methodology that combines an organized, systematic method of problem-solving with analysis and forecasting techniques derived from the study of patterns of invention in global patent literature. The development and improvement of products and technologies in accordance with TRIZ are guided by the laws of technical systems evolution.Royzen, Zinovy (1993). “Application TRIZ in Value Management and Quality Improvement”. SAVE PROCEEDINGS Vol. XXVIII, 94-101. https://trizconsulting.com/TRIZApplicationinValueManagement.pdf
TRIZ developed from a foundation of research into hundreds of thousands of inventions in many fields to produce an approach which defines patterns in inventive solutions and the characteristics of the problems these inventions have overcome. The research has produced three findings:
TRIZ applies these findings to create and improve products, services, and systems.
His work on what later became TRIZ was interrupted in 1950 by his arrest and 25-year sentence to the Vorkuta Gulag. The arrest was partially triggered by letters he and Raphael Shapiro sent to Joseph Stalin, ministers, and newspapers about Soviet government decisions they considered erroneous. Altshuller and Shapiro were freed during the Khrushchev Thaw which followed Stalin's death in 1953, and they returned to Baku. The first paper on TRIZ, "On the psychology of inventive creation", was published in 1956 in the Issues in Psychology ( Voprosi Psichologii) journal.
Altshuller observed clever and creative people at work, discovering patterns in their thinking with which he developed thinking tools and techniques. The tools included Smart Little Peoplereference Altshuller, G.S. (1984) Creativity as an Exact Science: the Theory of the Solution of Inventive Problems Translated by Williams, A. Gordon and Breach Science Publishers Inc] and Thinking in Time and Scale (or the Screens of Talented Thought).reference Altshuller, G.S. (1984) Creativity as an Exact Science: the Theory of the Solution of Inventive Problems Translated by Williams, A. Gordon, and Breach Science Publishers Inc]
In 1986, Altshuller's attention shifted from technical TRIZ to the development of individual creativity. He developed a version of TRIZ for children which was tried in several schools. After the Cold War, emigrants from the former Soviet Union brought TRIZ to other countries.
Altshuller screened patents to discover which contradictions were resolved or eliminated by the invention and how this had been achieved. He developed a set of 40 inventive principles and, later, a matrix of contradictions. Although TRIZ was developed from analyzing technical systems, it has been used to understand and solve management problems. The German-based nonprofit European TRIZ Association, founded in 2000, hosts conferences with publications.
BAE Systems and GE also use TRIZ, Mars has documented how TRIZ led to a new patent for chocolate packaging. It has been used by Leafield Engineering, Smart Stabilizer Systems, and Buro Happold to solve problems and generate new patents.
The automakers Rolls-Royce, (2025). 9780470741887, Wileys. ISBN 9780470741887 Ford, and Daimler-Chrysler, Johnson & Johnson, aeronautics companies Boeing, NASA, technology companies Hewlett-Packard, Motorola, General Electric, Xerox, IBM, LG, Samsung, Intel, Procter & Gamble, Expedia, and Kodak have used TRIZ methods in projects.
TOP-TRIZ is a modern version of developed and integrated TRIZ methods. "TOP-TRIZ includes further development of problem formulation and problem modeling, development of Standard Solutions into Standard Techniques, further development of ARIZ and Technology Forecasting. TOP-TRIZ has integrated its methods into a universal and user-friendly system for innovation."Royzen, Zinovy (2014), "TOP-TRIZ, Method for Innovation, Applications, Implementation." 5th International Conference on Systematic Innovation, San Jose, CA, July 16–18, 2014, Proceeding
In Liberating Structures, the facilitation method, also called TRIZ, was "inspired by one small element of" the original TRIZ methodology but is used in a distinct context. The method helps groups to identify and eliminate counterproductive practices by imagining the worst possible outcomes, recognizing current actions contributing to these scenarios, and designing practical steps to prevent them. This participatory approach emphasizes collaborative problem-solving within teams, setting it apart from the engineering-focused origins of the original TRIZ framework.
