Based on the extensive analysis of patents, the Theory of Inventive Problem Solving (TRIZ) describes a wealth of insights and methods developed from them for the systematic development of inventive solutions to problems. In particular, difficult problems where conventional solution concepts fail can be solved inventively step by step with the help of TRIZ. In Level 1 "Foundation", participants are introduced to the foundation course of TRIZ and already acquire parts of the tools and methods that they can use for problem analysis and solution search.
