Theory of Inventive Problem Solving (TRIZ) is a systematic innovation methodology. It is a structured methodology for modeling the problem, tools to work with the models and finally models of solutions for breakthrough idea generation. TRIZ is a recognized international science of creativity, based on the laws of physics and innovative patents distilled to numerous problem solving tools. It is a toolbox which provides users with methods to create breakthrough ideas. This book was written to enable an in-depth understanding of the philosophy, methodology and tools used. In addition, application of TRIZ in manufacturing (using semiconductor manufacturing examples) will further illustrate the power of TRIZ in providing a systematic approach from problem identification to innovative solution generation.
