Final answer:
The PDCA cycle was originally developed by Walter A. Shewhart and later modified and popularized by Dr. William Edwards Deming. It is a continuous improvement model comprising four steps: Plan, Do, Check, Act, used to improve processes and products in business and manufacturing.
Step-by-step explanation:
The person credited with developing the PDCA (Plan-Do-Check-Act) cycle is Dr. William Edwards Deming, an American statistician, professor, author, lecturer, and consultant. Although Deming is often associated with this cycle, it was originally developed by Walter A. Shewhart, who introduced the concept of Plan-Do-Study-Act (PDSA). Deming later modified Shewhart's model and popularized it in Japan in the post-World War II era. The PDCA cycle is a continuous improvement model used in business and manufacturing to improve processes and products.
The PDCA cycle is a four-step management method that businesses use for control and continuous improvement of processes and products. The four steps in the PDCA cycle are Plan, where objectives and processes necessary to deliver results are established; Do, where the plan is executed; Check, which involves monitoring and evaluating the executed plan against the results, and Act, where actions are taken to improve upon the process if the Check phase shows that the Plan phase which was implemented in Do is not being met.
