Investigations to root cause may conclude that no corrective or preventive actions are required, and additionally may suggest simple corrections to a problem with no identified systemic root cause.
The cycle of kaizen activity can be defined as: Plan → Do → Check → Act. This is also known as the Shewhart cycle , Deming cycle, or PDCA . Another technique used in conjunction with PDCA is the five whys , which is a form of root cause analysis in which the user asks a series of five "why" questions about a failure that has occurred ...
