This document discusses different methods for creative problem solving: analytical reasoning, analogical reasoning, and TRIZ method reasoning. Analytical reasoning involves identifying patterns to determine outcomes, analogical reasoning finds common relations between situations, and TRIZ is a Russian method that finds previously solved similar problems. The document provides examples of each method and outlines a 5-step TRIZ implementation process that involves defining the problem, finding a matching generalized problem, adapting the generalized solution, and checking if the problem is solved. It emphasizes that creativity is important for development and can be protected and preserved to maximize success.
