TRIZ is a methodology for systematic problem solving based on extensive research of inventions and patents. It provides benefits like reducing trial and error, finding compromise-free solutions, and predicting technology evolution. Key concepts of TRIZ include the laws of technological system evolution, contradictions that cause problems, and principles for resolving contradictions. TRIZ uses tools like the contradiction matrix and ARIZ algorithm to analyze problems and generate innovative solutions by applying separation principles and other heuristics. TRIZ has been adapted for use in solving IT problems by developing analogous concepts tailored for the IT domain.

31. Physical Contradiction & Separation Principle Same object must be in mutually exclusive physical states Depending on the state of object C, part A improves, while part B deteriorates, and vice versa C B A Improvement
35. Applying the Separation Principle Property P at time T 1 , anti-property -P at time T 2 Separation in Time One part has property P , another part has anti-property -P Separation in Space Object has property P , Its components have property -P Separation between the Whole and its Parts No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No
40. System Conflict Diagram Principle: Separation in Time Solution: Separate time and budget effects, in time, to avoid harmful effects
