PDCA cycle

This circular arrows diagram sample shows the four steps of plan–do–check–act (PDCA) management 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 circular arrows diagram example "PDCA cycle" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Basic Circular Arrows Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.
