Edwards Deming, widely attributed as the father of modern quality control. Madeline is a writer, communicator, and storyteller who is passionate about using words to help drive positive change. She holds a bachelor’s in English Creative Writing and Communication Studies and lives in Denver, Colorado. In her spare time, she’s usually somewhere outside (preferably in the mountains) — and enjoys poetry and fiction.
PDCA is an iterative, four-stage approach for continually improving processes, products or services, and resolving problems. The four steps can be repeated over and over as part of a never-ending cycle of continual learning and improvement. The PDCA process supports both the principles and practice of continuous improvement and Kaizen. Kaizen focuses on applying small, daily changes that result in major improvements over time. The PDCA Cycle provides a framework and structure for identifying improvement opportunities and evaluating them objectively. Using PDCA, an organization undergoing continuous improvement can create a culture of problem solvers and critical thinkers.
The greatest waste is failure to use the abilities of people.
Human transformation hinges on the idea that we can better ourselves and our organizations. So when it comes to the continuous improvement process (Plan, Do, Check and Act or PDCA), it’s an investment in reaching our full potential. This journey isn’t a one-size-fits-all when it comes to implementing improvement strategies or improvement techniques. It’s a deliberate process that requires observation, analysis, planning, and action.
The developed which of the following is iterative four stage approach for continually improving the process Kaizen methodology includes doing small experiments and monitoring results, then adjusting when new improvements are suggested. To apply this concept in practice, the PDCA cycle provides a framework to promote improvements continuously. At the “Check” stage in PDCA, the team needs to audit its plan’s execution and see if its initial plan worked. In contrast, the “Study” stage in PDSA aims to analyze in depth the results of any change applied at each step, ensuring long-term process improvements. Either way, you can use both models by studying and checking the results obtained from tests.
Lean Development with Plan-Do-Check-Act Iterative Process
- Afterwards we will discuss how the PDCA cycle can support Kaizen and continuous improvement.
- Applications are possible in change management, product development, project management, and quality improvement.
- This model was redesigned by the Japanese Union of Scientists and Engineers (JUSE) in 1951 and became what we know today as a PDCA cycle.
- TQM incorporates various tools and methods, including the PDCA’s philosophy.
- They would then evaluate the effect of this change by monitoring the process closely.
Also known as Kaizen, the continuous improvement method originated in Japan. Today, it’s been adopted by businesses across the globe as a way to achieve operational excellence. Sometimes, continuous improvement is the smallest change that adds up over time. Other times, continuous improvement goes hand-in-hand with adapting to change and building resilience to stay competitive in today’s market. Regardless, the process generates results without the pain that comes with making big changes at once.
This plan should involve the people who are responsible for the steps in your process. Brainstorm potential solutions and then choose the one that promises to be most effective. In addition to reducing waste, continuous improvement can also help you save money in other ways. For example, by streamlining your process, you may be able to reduce the amount of inventory you need on hand.

This should be done cautiously to limit disruptions in case the plan does not have the expected results. Edward Deming expanded the Shewart cycle into a four-step pattern for Japanese audiences. The Deming cycle related heavily to the concept of product quality, innovation, and learning-by-doing over the entire life cycle of a product. If everything seems perfect and your team managed to achieve the original goals, then you can proceed and apply your initial plan.
What Is the PDCA (Plan-Do-Check-Act) Cycle?
The lean process described above is one of the central themes in Mike Rother’s excellent book Toyota Kata. In it he describes the improvement kata that Toyota use to manage people and achieve superior results. This kata is based on understanding the current situation, determining the desired situation and then using repeated PDCA cycles to get there. The “act” stage, also called the “adjust” stage, is where the process is actually improved. If the PDCA cycle is determined to be a success, the team can proceed to implement and adopt the initial plan.
If you work through the steps of the PDCA cycle multiple times, you should find better and better ways to produce your work. In the long run, you’ll do a better job with fewer resources, creating more efficiency, less waste, and a higher-quality product. In 1951, the Japanese Union of Scientists and Engineers (JUSE) altered Deming’s framework into the more recognizable PDCA cycle. PDCA is an improvement cycle based on the scientific method of proposing a change in a process, implementing the change, measuring the results, and taking appropriate action. The cyclical nature of this model allows teams to identify and remove defects early in the process and restart the cycle until the desired outcome is reached.
