We expected that TRIZ is the thinking methods extracted from a huge number of past patents. Problem is defined Porblem analysis reveals the “ Analysis why why ” as the gap. constraints tacit in the system. It may be regarded as the basic, general principles when humans think, and hence should also be effective when software crutial task ＜Why we cannot ?＞ engineers think on their problems.
