TRIZ Local Quality Principle

TRIZ is an acronym for the Russian theory of inventive problem solving. The theory was developed by Genrich Altshuller and his associates, who studied over four million patents in order to identify patterns in invention. TRIZ includes a number of principles and tools, one of which is the principle of local quality. This principle states that it is usually easier and more effective to improve the quality of a product or system in a small, localized area, rather than trying to improve the quality of the entire product or system all at once. For example, if a car engine is not running smoothly, it would be easier to fix the problem by replacing a damaged spark plug or oil filter, rather than by trying to repair the engine as a whole. The principle of local quality can be applied to many different types of problems, and it is an important tool for inventors and engineers.
