TOP-TRIZ guides you to identify what happened and why it happened, then develop the improvements needed to eliminate the problem. It handles root cause & corrective action much faster than conventional methods including five whys, fishbone diagrams and brainstorming — especially for problems with multiple causes.
The key difference: we pretend the failure is a desired result and use Build Sufficient Functions to invent how to produce it using available resources, then guide elimination of the revealed causes using Harmful Action Elimination and the Conflict Solving Algorithm.
For example, a team had been working for years on revealing the cause of an electric arc inside a fuel pump electrical connector. It took just two hours for a team using TOP-TRIZ to reveal the set of events leading to the failure and determine multiple ways to eliminate the problem completely. Some solutions were patented in the US and other countries.
