A process model for application of TRIZ

The theory of inventive problem solving (TRIZ) is mainly applied to developing substituted technology with higher performance than current one. It usually starts from problems or forecasting. TRIZ provides several powerful tools based on knowledge for solving problems, but it lacks of a systematic programming for the application of these tools in an enterprise. This paper provides a systematic framework for the application of TRIZ, which divides the application into two levels: strategic level and tactical level. The technology maturity is used as the main criterion for casting a strategy. The Level of Solution is used as a framework for integrating tools of TRIZ. A process model is put forward as a guideline for the application of TRIZ from views of strategy and tactics. As an illustration the process model is applied to a company for improving performance of butterfly valve.
