Shewhart cycle PDCA methodology

Another problem-solving methodology popular with lean thinkers is the PDCA problem-solving loop. PDCA (plan-do-check-act) is an iterative four-step problem-solving process typically used in business process improvement. It is also known as the Demlng cycle, Shewhart cycle, Deming wheel, or Plan-Do-Study-Act. 

At the core of these elements is the simple concept of a PDCA methodology, called the Shewhart cycle (Shewhart, 1931), that can equally be applied to all safety management systems. PDCA has been at the root of quality control and safety programs. The Shewhart cycle has been adapted within the framework of many voluntary compliance standards such as ANSI ZlO-2012 Occupational Safety Process (Occupational Health and Safety Systems, 2012). Refer to Figure 6.1, Shewhart, PDCA Cycle for Learning and Improvement .
