TRIZ - Theory of Inventive Problem Solving is a systematic way to make thinking Lean
provided at the first place we actually think !
The problem is our minds are not designed to think hence elimination of waste from the thinking process does not arise at all!
Hence any method which (1) forces us to think actually create a mental fatigue (2) any method that eliminates waste in our thinking actually considered very complex as - since we don't think at all where is the chance of waste!
A Random thought, just like that...........
