The plan–do–check–act cycle. PDCA or plan–do–check–act (sometimes called plan–do–check–adjust) is an iterative design and management method used in business for the control and continual improvement of processes and products. [1] It is also known as the Shewhart cycle, or the control circle/cycle.
The plan–do–check–act cycle is an example of a continual improvement process. The PDCA (plan, do, check, act) or (plan, do, check, adjust) cycle supports continuous improvement and kaizen. It provides a process for improvement which can be used since the early design (planning) stage of any process, system, product or service.
PDSA may refer to: PDSA (plan–do–study–act), a quality improvement process; People's Dispensary for Sick Animals, a UK veterinary charity;
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 ...
A control chart can be useful during the Control stage to assess the stability of the improvements over time by 1. serving as a guide to continue monitoring the process and 2. providing a response plan for each of the measures being monitored in case the process becomes unstable. Standard operating procedures (SOP's) and Standard work
"PDCA is associated with W. Edwards Deming, who is considered by many to be the father of modern quality control; however, he used PDSA (Plan-Do-Study-Act) and referred to it as the "Shewhart cycle". Later in Deming's career, he modified PDCA to "Plan, Do, Study, Act" (PDSA) because he felt that "check" emphasized inspection over analysis."
Sense-Plan-Act was the predominant robot control methodology through 1985. Sense - gather information using the sensors; Plan - create a world model using all the information, and plan the next move; Act; SPA is used in iterations: After the acting phase, the sensing phase, and the entire cycle, is repeated.
There are six main activities, which jointly form the change request management process. They are: Identify potential change, Analyze change request, Evaluate change, Plan change, Implement change and Review and close change. These activities are executed by four different roles, which are discussed in Table 1. The activities (or their sub ...
