Plan-Do-Check-Act (PDCA)

This circular arrows diagram sample depicts the Plan–Do–Check–Act cycle.
"PDCA (plan–do–check–act or plan–do–check–adjust) is an iterative four-step management method used in business for the control and continuous improvement of processes and products. It is also known as the Deming circle/ cycle/ wheel, Shewhart cycle, control circle/ cycle, or plan–do–study–act (PDSA). Another version of this PDCA cycle is OPDCA. The added "O" stands for observation or as some versions say "Grasp the current condition." This emphasis on observation and current condition has currency with Lean manufacturing/ Toyota Production System literature." [PDCA. Wikipedia]
The diagram example "PDCA cycle" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Circular Arrows Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.

"Rate of change, that is, rate of improvement, is a key competitive factor in today's world. PDCA allows for major "jumps" in performance ("breakthroughs" often desired in a Western approach), as well as Kaizen (frequent small improvements). In the United States a PDCA approach is usually associated with a sizable project involving numerous people's time, and thus managers want to see large "breakthrough" improvements to justify the effort expended. However, the scientific method and PDCA apply to all sorts of projects and improvement activities." [PDCA. Wikipedia]
The plan-do-check-change diagram example "Effective practice PDCA" was designed using ConceptDraw PRO software extended with Plan-Do-Check-Act (PDCA) solution from Management area of ConceptDraw Solution Park.

"PDCA was made popular by Dr W. Edwards Deming, who is considered by many to be the father of modern quality control; however, he always referred to it as the "Shewhart cycle"." [PDCA. Wikipedia]
"Quality management ensures that an organization, product or service is consistent. It has four main components: quality planning, quality assurance, quality control and quality improvement. Quality management is focused not only on product and service quality, but also on the means to achieve it. Quality management, therefore, uses quality assurance and control of processes as well as products to achieve more consistent quality." [Quality management. Wikipedia]

"Shewhart described manufacture under "control"—under statistical control—as a three-step process of specification, production, and inspection. ...
Shewhart intended the analyst to take action based on the conclusions of the evaluation. According to Deming, during his lectures in Japan in the early 1950s, the Japanese participants shortened the steps to the now traditional plan, do, check, act. Deming preferred plan, do, study, act because "study" has connotations in English closer to Shewhart's intent than "check"." [PDCA. Wikipedia]
