Deming Cycle: A Proven Approach to Quality Improvement

Total Quality Management is a process businesses use to improve the quality of their products and services. One of the critical components of TQM is the Deming Cycle, a four-step process for continuous improvement. The Deming Cycle can be used in any business or organization to improve quality and productivity.

Read this article to know what Deming Cycle is and how you can use it to improve your business.

What Is the Deming Cycle?

The Deming Cycle, also known as the Plan-Do-Study-Act (PDSA) Cycle, is a continuous quality improvement model that consists of four key stages: Plan, Do, Study, and Act. The cycle was first put forth by an American statistician, Dr. W. Edwards Deming, in the 1940s to improve quality control in manufacturing and has since been adopted by businesses and organizations across various industries.

While the cycle can be applied to any process or problem, it is often used as a tool for root cause analysis. By breaking down a problem into these four stages, businesses can more effectively identify issues and develop solutions that prevent problems from occurring again. The Deming Cycle is an essential quality improvement tool in various industries and business applications.

How To Use The Deming Cycle For Your Business

The Deming Cycle is a continuous quality improvement model that consists of four key stages: Plan, Do, Study, and Act. Also known as the PDSA Cycle, it is an iterative process that helps organizations identify and correct problems to improve quality. 

When using the Deming Cycle, it is vital to keep the following in mind:

  • It is important to remember that the cycle is designed to be used as an ongoing process, not a one-time event. 

  • The cycle should be used to help identify areas for improvement, not as a way to find blame. 

  • It is crucial to keep communication open and honest throughout the process. 

By following these guidelines, you can ensure that your organization uses the Deming Cycle effectively and efficiently. Now, how do you use the Deming cycle for continuous business improvement? 

The Deming cycle can be used by following the four steps: Plan, Do, Study, and Act

4 Stages of the Deming Cycle

  1. Plan- 4 Stages of the Deming Cycle

Planning is the first cycle stage focused on identifying the problem and developing a plan to address it. This stage begins with identifying a problem or opportunity for improvement. Once the problem has been identified, the team responsible for addressing it will develop an action plan. This plan will identify who will do what, when it will be done, and how it will be done. 

The goal of this stage is to develop a clear and concise plan that can be followed to address the identified problem. By planning out the steps necessary to address the issue adequately, the team can increase their chances of achieving their desired results.

  1. Do- 4 Stages of the Deming Cycle

Doing is the second step in the PDSA cycle. It is when the plan from the previous step is put into action. You will take the information and analysis from the previous steps and use them to make changes in your process. These changes should improve your product or service and prevent future problems. This is where changes are made, and improvements are implemented. It's important to note that this step should not be rushed - care should be taken to ensure that changes are made correctly and will have the desired effect. 

Once the changes have been made, it's time to move on to the next step: Studying whether or not the changes had the desired effect.

  1. Study- 4 Stages of the Deming Cycle

It is essential to constantly reflect on past performance and learn from mistakes to improve quality. This is the third step in Deming Cycle, known as Study. Only through studying past performance can organizations hope to identify problems and make necessary improvements.

There are many different ways to study past performance. One standard method is to review records and identify any patterns or trends. Another approach is to interview employees or customers to get feedback about what could be improved.

Whatever method is used, the study's results must be used to make organizational changes. Without taking action based on the findings, there is no point in conducting a study in the first place. By using the insights gained from the study, organizations can move closer to their goal of continuous improvement.

  1. Act- 4 Stages of the Deming Cycle

This fourth and last step refers to taking corrective action based on the results of the previous three steps. This may involve changing how things are done to improve quality. It is important to note that the Deming Cycle aims not simply to fix problems but to prevent them from happening in the first place.

Corrective action should be taken as soon as a problem is identified. This will help to ensure that quality standards are met and maintained. It is also essential to review the effectiveness of corrective action taken to make further improvements if necessary.

Deming Cycle’s Best Practices

  1. Identify the problem or opportunity for improvement.

One of the Deming Cycle's best practices is identifying the problem or opportunity for improvement. This helps organizations to focus on areas that need improvement and make necessary changes.

Organizations need to establish a baseline to identify the problem or opportunity for improvement. This will help them to track progress and identify areas that need improvement. Once the baseline is established, organizations can then set goals and objectives. They can also develop plans to address the identified problems or opportunities for improvement.

Organizations need to constantly monitor their progress to ensure that they are making progress toward their goals. They should also review their plans periodically to ensure they are still relevant and practical. By following these steps, organizations can effectively identify problems or opportunities for improvement and make necessary changes.

2. Set objectives and goals for the improvement project.

When it comes to quality improvement, one of the best practices is to set objectives and goals for the project. This helps ensure everyone knows what needs to be accomplished and can work together to ensure it happens.

Having objectives and goals also allows you to track progress and see if you are on track to meet your targets. Without this, it can be difficult to tell if your improvement efforts are making a difference.

Finally, setting objectives and goals gives you something to strive for and keeps everyone motivated. It can be easy to get bogged down in the day-to-day details of a quality improvement project, but remembering the bigger picture can help keep things on track.

3. Plan and implement the improvements.

Planning and implementing help organizations focus on the areas that need improvement and work on making those improvements.

When using Deming Cycle, it is crucial to have a clear plan of what needs to be improved. Once the plan is in place, the organization can then work on implementing the changes. This may involve changes to processes, training employees, or making other changes to improve the organization's overall quality.

Improvements can be challenging, but organizations can make significant progress using Deming Cycle and following best practices. Organizations can create a cycle of success by taking action and continuously improving.

4. Monitor and control the implementation process.

Continuous monitoring and controlling of the implementation process can help organizations ensure that their improvements are being implemented as planned and have the desired effect.

Organizations should establish clear metrics for measuring progress and identify who is responsible for monitoring and controlling the implementation process. They should also set up a system for tracking progress and ensuring that any problems that arise are quickly addressed.

Monitoring and controlling the implementation process is essential to successful improvement efforts. By following these best practices, organizations can ensure that their improvements are executed smoothly and effectively.

3. Evaluate the results of the improvements.

Evaluating the results of improvements made to a process is an integral part of the Deming Cycle. By doing so, businesses can determine whether the changes have had the desired effect and make further adjustments. This feedback loop ensures that quality improvements are made on an ongoing basis. Additionally, this enables organizations to identify any potential problems that may have arisen due to the changes. 

Several methods can be used to evaluate the results of improvements made to a process. One standard method is to compare performance metrics before and after the change is implemented. Another way to evaluate results is to solicit feedback from customers or employees affected by the change.

4. Make necessary adjustments to the plan based on evaluation results.

One of the Deming Cycle's best practices is making necessary adjustments to the plan based on evaluation results. This helps ensure that the plan is always relevant and up-to-date and that any changes are made promptly.

Making adjustments to the plan based on evaluation results also helps identify areas where the plan may need to be revised or updated. This can help prevent problems or issues from arising in the future.

Making adjustments to the plan based on evaluation results is a critical best practice of the Deming Cycle that can help keep the plan relevant and up-to-date. By making these adjustments, organizations can improve their overall performance and avoid potential problems down the road.

5. Standardize and document the new process or product.

When implementing a new process or product, it is vital to standardize it across all departments and locations. This will ensure that everyone is on the same page and that there are no discrepancies. Doing this can prevent potential issues arising from having different versions of the same thing.

Standardizing new processes or products is crucial because it helps ensure consistency and quality. When all employees use the same process or product, it is easier to identify problems and find solutions. Additionally, standardized processes or products are easier to train employees on and improve efficiency.

Moreover, it is also essential to document the new process or product. This documentation should include all aspects of the change, such as who was involved, what was changed, when, and why. This will help ensure that everyone knows the changes and can easily reference them if needed.

6. Sustain the improvements over time.

Sustaining the improvements is a critical component of the Deming Cycle. The cycle starts with a plan, followed by doing, studying, taking action, and then reflecting on results and adjusting the plan accordingly. This iterative process continues until desired results are achieved.

Once improvements are made, it is crucial to maintain those changes over time to ensure that the benefits are realized. To do this, it is necessary to have a system in place to track progress and identify any areas where further improvement is needed. Additionally, regular communication among all stakeholders helped to keep everyone on track and focused on sustaining the improvements.

Sustaining improvements over time requires commitment from everyone in the organization. Tops managers must provide leadership and direction, middle managers must plan and implement changes, and front-line workers must carry out the day-to-day work.

The Benefits Of the Deming Cycle
