Tools of Theory of Inventive Problem Solving Used for Process Improvement-A Systematic Literature Review

One of today's great challenges is radical process improvement. TRIZ (theory of inventive problem solving) could help to resolve this. This study aims to answer the following research question: Which tool of TRIZ is best for process improvement? To answer this, a systematic literature review was conducted, and the gathered data were analyzed. The main focus was on the tools, the rate of improvement, the improved parameters, and the combination of tools. The results show that the technical contradiction with inventive principles should be easy to use and provide sufficient results. If the technical contradiction is not enough or the process is too complex, an algorithm or framework to use more advanced tools of TRIZ should be used. That should help to resolve the most challenging problems related to radical process improvement.
