PDCA (Plan-Do-Check-Act) is an iterative, four-stage approach for continually improving processes, products or services, and for resolving problems. It involves systematically testing possible solutions, assessing the results, and implementing the ones that have shown to work. It is based on the scientific method of problem-solving and was popularized by Dr W. Edwards Deming, who is considered by many to be the father of modern quality control. While Six Sigma provides the framework for determining what is slowing the process, methods like PDCA explain the steps to identify and eliminate issues.
What Is the Difference between PDCA and Total Quality Management (TQM)?
- This means you can get your product or service to the market faster and start seeing results sooner.
- Building resilience as an organization is no longer a nice to have.
- Continuous improvement is the process of making small incremental changes that add up to significant results based on deliberate observation of current processes.
- Using data, the team can make adjustments to the solution and reassess the hypothesis.
- Through careful planning, disciplined execution, rigorous checking, and decisive action, PDCA enables organizations to drive change effectively and sustain improvements.
If you’re using Lean methodology to get the most out of your iterative processes, you need to get familiar with the PDCA cycle. Go through the steps each time you need to make an improvement to your process, and which of the following is iterative four stage approach for continually improving the process your team will get better and better over time. In the end, you’ll produce better work faster and with fewer resources, which eliminates waste and gets your customers exactly what they’re looking for. Through careful planning, disciplined execution, rigorous checking, and decisive action, PDCA enables organizations to drive change effectively and sustain improvements.
These pilot programs can also help minimize disruptions to other ongoing business operations. If your organization uses Lean methodology, you’re focused on reducing waste at every step of your process. Lean methodology is all about using only the truly necessary resources and time to create great products.

In addition, Nestlé Waters is an example of how techniques such as Value Stream Mapping (VSM) can help illustrate the flow of materials and information from raw material to the final product. As a result of implementing this process, the bottling plant has experienced a significant increase in its process efficiency. It can be appropriate to adopt the whole plan if objectives are met. Respectively, your PDCA model will become the new standard baseline.

Instead, they figure out what works as they go, which may mean that the timeline for when the work will be done is hard to pin down. Finally, you arrive at the last stage of the Plan-Do-Check-Act cycle. Keep in mind you and your team may need to go through the plan a couple of times before being able to proceed.
As noted earlier, the PDCA cycle can be used wherever change or continuous improvement is required. Furthermore, do the tests support initiative or project objectives? Even successful tests may have problems or inefficiencies that offer room for improvement. The PDCA Cycle is a good example of the power of iterative learning and improvement. From its inception by Shewhart to its widespread adoption due to Deming’s advocacy, it has become a key tool of operational excellence. This phase is where you review the data collected during the trial and determine if the changes made led to an improvement.
If you’re not investing serious thought at the beginning to define the scope of your project, you could end up getting distracted by side issues that pop up as you’re completing your work. The language may change slightly, but the basic thinking has not changed much. Consider the three-phase concept—Build, Measure, Learn—popularized by Eric Ries in his book, The Lean Startup. His iterative process is fundamentally similar to both the original Shewhart and Deming cycles. Words may change or be slightly altered, but the timeless, classic concepts stay the same.
