In business, PDCA is an iterative design and management method used for process and product control and continuous improvement. Other names include the Deming circle/cycle/wheel, the Shewhart cycle, the control circle/cycle, and the plan–do–study–act. PDCA is another name for this PDCA cycle. When a team starts new product development, this is a common example of the PDCA cycle. PDCA has several significant advantages: It continuously encourages people and processes to improve. It allows your team to experiment with potential solutions on a small scale and controlled environment. It keeps errors from recurring in the work process.
