What's it about?
The 5 Whys is a lean assessment and analysis tool for problem solving, concept testing, and quality control based primarily on the scientific approach created by Toyota, and adopted by Kaizen, Six Sigma and lean manufacturing practices globally. It starts by identifying the problem at hand, asks "Why?" to determine the main cause(s), the Q/A session is repeated up to four additional times just to identify and reach the root or source cause(s) in order to find a precise and accurate solution which will prevent the problem from recurring.
Who should use it
Best suited for product/service manufacturers, managers, analysts, and creative thinkers interested in problem solving and exploring the causes and associated risks, dependencies and symptoms of the observable problem or challenge.
