By the end of this post, you will have a comprehensive understanding of the PDCA cycle and how it can help your organization to achieve continuous improvement.
Origin and history of the Deming Wheel PDCA cycle
The PDCA cycle, also known as the Deming Wheel or Deming Cycle, was developed by Dr. W. Edwards Deming, a renowned statistician and quality management expert. Dr. Deming advocated using data and statistical analysis to improve quality and productivity in organizations.
In the 1950s, he introduced the PDCA cycle as a framework for continuous improvement in the manufacturing process. The PDCA cycle was popularized by Dr. Deming’s book “Out of the Crisis,” published in 1986. In the book, he explained the concept of the PDCA cycle and how it could be used to achieve continuous improvement in any process.
Today, the PDCA cycle is widely used in various industries, including manufacturing, healthcare, education, and service organizations, as a continuous improvement and quality management tool.
What is Deming Wheel PDCA Cycle?
The PDCA cycle is a four-stage problem-solving framework organization can use to improve their processes, products, and services continually. The four stages of the Deming Wheel PDCA cycle are:
04 Stages of Deming Wheel PDCA Cycle
The first stage of the PDCA cycle is “Plan,” which involves identifying a problem or opportunity and developing a plan to address it. This stage includes defining the problem, setting goals, and developing a plan to achieve those goals. In this stage, involving the stakeholders affected by the change is essential to ensure their buy-in and commitment to the plan.
An example of the “Plan” stage of the PDCA cycle is a company that wants to reduce its production costs. The first step would be to identify the problem, which is the high production cost. The company aims to reduce production costs by 20% in six months.
The team would then develop a plan that would include analyzing the production process to identify inefficiencies, testing new methods to reduce costs, and obtaining feedback from the production team.
The team would also involve stakeholders such as suppliers and customers to ensure that their needs and concerns are considered in the plan. The plan would be documented, and everyone involved would understand their roles and responsibilities in the implementation.
The second stage of the PDCA cycle is “Do,” which involves implementing the plan developed in the “Plan” stage. This stage includes executing the plan and collecting data to monitor its effectiveness. It is essential to ensure that everyone involved in the implementation understands their roles and responsibilities and has the resources they need to carry out their tasks effectively.
An example of the “Do” stage of the PDCA cycle is implementing the plan to reduce production costs in the previous stage. The team would start executing the plan, including testing new production methods, training the production team, and tracking production costs.
The team would also collect data on the production process and analyze it to identify any issues or inefficiencies. During this stage, it is crucial to ensure the plan is executed and any issues are addressed promptly.
Suppose the team identified that the production team struggled to adapt to the new production methods. In that case, they would provide additional training and support to help the team understand the new methods and how to implement them effectively. The team would also collect data on the production costs and analyze them to ensure that they are on track to reduce production costs by 20%.
The third stage of the PDCA cycle is “Check,” which involves measuring the results of the plan implemented in the “Do” stage. This stage includes comparing the actual and expected results, identifying any deviations, and analyzing the data to understand the root causes of the deviations. The analysis helps identify whether the plan successfully achieved its goals and whether any modifications are necessary.
An example of the “Check” stage of the PDCA cycle is analyzing the production cost data collected in the “Do” stage to identify any deviations from the expected results.
Suppose the team expected a 20% reduction in production costs, but the data showed only a 10% reduction. In that case, the team would analyze the data to identify the root causes of the deviation. They may find that the new production methods are not as efficient as expected or that the production team needs additional training.
The team would also analyze the data to identify trends or patterns that could provide insights into the production process’s performance. The team would then compare the actual and expected results to determine the plan’s success in achieving its goals. Based on the analysis, the team would determine whether any modifications to the plan are necessary to achieve the desired results.
The fourth and final stage of the PDCA cycle is “Act,” which involves taking corrective action based on the analysis results conducted in the “Check” stage. This stage includes implementing modifications to the plan or process to improve its effectiveness and then starting the PDCA cycle again to continue the continuous improvement cycle.
An example of the “Act” stage of the PDCA cycle is modifying the production process to address the root causes of the deviation in the production cost reduction plan identified in the “Check” stage. Suppose the team identified that the new production methods were less efficient than expected.
In that case, they may test additional methods to identify the most efficient process. The team would also provide additional training to the production team to ensure they understand and implement the new methods effectively.
After implementing the modifications, the team would start the PDCA cycle again, starting with the “Plan” stage. The team would identify new problems or opportunities and develop a new plan to address them.
The cycle continues, with each iteration bringing the organization closer to its goals and achieving continuous improvement. By continuously applying the PDCA cycle, organizations can achieve incremental improvements in their processes and products, improving customer satisfaction and increasing efficiency.
How to Implement the Deming Wheel PDCA Cycle?
Implementing the Deming Wheel PDCA cycle involves six essential steps that organizations can follow to achieve continuous improvement:
1. Identifying a process for improvement: The first step is to identify a process that requires improvement. This could be a business process, a production process, a service process, or any other process within the organization.
2. Defining the problem or objective: Once the process has been identified, the next step is to define the problem or objective that needs to be addressed. The problem or objective should be clear, specific, measurable, and achievable within a defined time frame.
3. Analyzing the process: The third step involves analyzing the process to identify any areas that need improvement. This could involve gathering data, conducting surveys, or performing root cause analysis to identify the underlying causes of the problem.
4. Developing and implementing a solution: Based on the analysis conducted in the previous step, the next step is to develop and implement a solution to address the problem or achieve the objective. The solution should be specific, measurable, achievable, relevant, and time-bound.
5. Measuring the results: After implementing the solution, the next step is to measure the results to determine whether the solution has effectively addressed the problem or achieved the objective. This could involve collecting data, conducting surveys, or performing statistical analysis to determine the solution’s impact.
6. Standardizing the solution: The final step is to standardize the solution to ensure that it is incorporated into the organization’s processes and becomes a part of its culture. This could involve documenting the solution, training employees, or modifying the organization’s policies and procedures to ensure the solution is integrated into the organization’s processes.
