TRIZ is the Russian acronym for the “Theory of Inventive Problem Solving,” an international system of creativity developed in Russia.
One can think of TRIZ as another way of Lateral Thinking. TRIZ is either jumping to solutions OR starting from scratch. According to TRIZ, universal principles of creativity form the basis of innovation. TRIZ identifies and codifies these principles, and uses them to make the creative process more predictable. TRIZ is most useful in roles such as product development, design engineering, and process management.
TRIZ is based on two basic principles
- Somebody, sometime, somewhere has already solved your problem or one similar to it. Creativity means finding that solution and adapting it to the current problem.
- Don’t accept contradictions. Resolve them
TRIZ provides a range of strategies and tools for finding inventive solutions. It provides a structured way of doing innovations and changes the way a engineer would approach a problem. TRIZ is developed by analyzing patents . Thus when TRIZ is applied to solve a problem it brings the vast knowledge available in patents database.
TRIZ is a set of systematic thinking tools and uses a distillation of all recorded solutions in 4 simple lists:
- 40 inventive principles
- 8 trends of technical evolution
- 76 standard solutions
- 2500+ engineering & scientific concepts arranged as questions and answers
TRIZ offers 4 ways to resolve physical contradictions by separating contradictory requirement
- Time (Try to schedule the process so that conflicting requirements, functions, or operations take
effect at different times.)e.g. Reviews in a team can be conducted at a separate fixed time
- Space (Separate contradictory requirements, functions or conditions by assigning each one to a different location.) e.g. There can be a separate space to perform a specialized functions
- Condition (Look for a parameter or condition that can change so the system can meet one
requirement under one condition and the opposite requirement under another condition.)
- Alternative Ways/Structure (Try to separate contradictory requirements, functions or conditions between different structural elements of the system.)
These are the 40 inventive principles that have been used in hundreds of thousands of patents. You can use them via TRIZ Contradiction Analysis or standalone, as stimuli to prod your thinking forward.

Although TRIZ was developed from the analysis of technical systems, it has been used widely as a method for understanding and solving complex management problems.
- Samsung uses TRIZ heavily. In 2003 TRIZ led to 50 new patents for Samsung .
- Rolls-Royce, BAE Systems and GE are all documented users of TRIZ.
- Mars has documented how applying TRIZ led to a new patent for chocolate packaging.
- TRIZ has also been used successfully by Leafield Engineering, Smart Stabilizer Systems and Buro Happold to solve problems and generate new patents.
- Rolls-Royce, Ford, and Daimler-Chrysler, Johnson & Johnson, Boeing, NASA, Hewlett Packard, Motorola, General Electric, Xerox, IBM, LG, Samsung, Intel, Procter and Gamble, Expedia and Kodak have used TRIZ methods in some projects.
- The application of TRIZ tools in numerous German industrial companies in the recent decade has followed the principles of the Advanced Innovation Design Approach, which recommends application of the selected TRIZ tools in the early stage of the innovation process for the identification of customer needs, comprehensive problem definition and ideation, new concept development and optimization.
