Since then, this method has been spread out through just about every type of industry around the world, and is a component of Kaizen, Six Sigma, and lean manufacturing.
It was the basis of their 'scientific approach' to problem solving. This system was implemented throughout their manufacturing facilities as part of their overall methodological strategy. The five whys technique began at the Toyota Motor Company with Sakichi Toyoda.
