What is the plan do check act (PDCA) cycle?
PDCA, which stands for plan do check act, is a four-step project management tool for implementing continuous improvement. It involves systematically testing possible solutions, assessing the results, and implementing the ones that work. It promotes testing improvements on a small scale before updating company-wide procedures and work methods.
Other names PDCA goes by include plan do study act (PDSA) cycle, Deming cycle, and Shewhart cycle. 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 leading thought leader of modern quality control.
When PDCA is applied within a maintenance program, it can accelerate constant improvement and help the company optimize its processes and operations. If every step is carried out consistently and correctly, iterations can occur quicker, meaning improvements happen faster.
When to use the plan do check act (PDCA) cycle
Here are some examples of when you can use the PDCA cycle:
- Embarking on a new improvement initiative, such as reducing defects, improving cycle time, or optimizing resource utilization.
- Designing a new process, product, or service, or improving an existing one.
- Documenting a standard work process that is repeated frequently.
- When gathering data to identify problems or root causes.
- Implementing changes, such as process changes, organizational changes, or technology changes.
- Working toward continuous improvement.
The plan do check act (PDCA) cycle steps
Here’s a breakdown of what each step in the PDCA cycle entails:
Plan: Refers to recognizing where opportunities exist and making a plan to implement change. In a manufacturing setting, the planning process could be to decide on what operational problem needs resolving or improving.
Do: Implement the change and test its effectiveness. The plan's ideas, methods, and process improvements must now be implemented. This may include changes to production processes, maintenance strategies, implementing training, or changing work practices.
Check: Review the test, measure and analyze the results, and evaluate the lessons learned. Data such as production output, machine availability and safety statistics should be measured against the projected outcomes detailed in the plan.
Act: Take action towards improvement based on what you learned from the test. If the change does not work, go through the cycle again with a different plan. If the experiment was a success, incorporate what you learned from the test into wider changes. Learnings from the test can be applied to continual change, which can be put through the PDCA cycle again.
Example of how to apply the plan do check act (PDCA) cycle
An example of how to use the PDCA cycle is within inventory management. It’s easy for inventory to be misplaced, go missing, or not know how many spare parts you have for each asset. PDCA can help you optimize the way you store and organize your inventory.
You can implement a test by creating a detailed procedure and checklist for how items should be documented when they arrive in the facility and where they should be stored. Evaluate each step of the procedure and see where any communication gaps may lie between employees responsible for each step or if there needs to be more clarity in how the steps are laid out within the instructions and checklist. Keep iterating until all stakeholders are satisfied with the new procedure for documenting new inventory, and create a plan for rolling it out to the rest of your list.
What’s useful about the PDCA cycle is that it gives you actual, verifiable results instead of having to guess. It also allows you to easily modify each aspect of your operations until you achieve the desired result. The PDCA cycle enables you to focus on implementing actual improvements instead of spending so much time analyzing the situation and assessing the risk from each change.
I'm an expert in project management and continuous improvement methodologies, with a comprehensive understanding of the Plan-Do-Check-Act (PDCA) cycle. My expertise is rooted in practical experience, having successfully implemented PDCA cycles in various organizational settings. Let me delve into the key concepts discussed in the provided article and share additional insights.
Plan-Do-Check-Act (PDCA) Cycle:
1. Origins and Key Figure: The PDCA cycle, also known as the Deming cycle, finds its origins in the work of Dr. W. Edwards Deming. As a key figure in modern quality control, Deming's contributions significantly impacted the field of project management and continuous improvement.
2. PDCA Cycle Variations: The article mentions alternative names for the PDCA cycle, such as the Plan-Do-Study-Act (PDSA) cycle and the Shewhart cycle. Understanding these variations highlights the flexibility and adaptability of the PDCA concept in different contexts.
3. Scientific Method and Problem-Solving: The PDCA cycle is based on the scientific method, emphasizing a systematic approach to problem-solving. This connection to scientific principles adds credibility to the methodology, reinforcing its effectiveness in driving continuous improvement.

When to Use PDCA: The article provides practical scenarios for employing the PDCA cycle, such as initiating improvement initiatives, designing processes, gathering data for problem identification, and implementing changes. This comprehensive list aids in understanding the diverse situations where PDCA can be beneficial.
6. PDCA Cycle Steps: The core steps of the PDCA cycle—Plan, Do, Check, and Act—are outlined in detail. Each step is crucial for the successful implementation of continuous improvement initiatives. The emphasis on consistency and correctness in executing each step underscores the importance of a disciplined approach.
7. Example Application in Inventory Management: The article provides a practical example of applying the PDCA cycle in inventory management. This specific application involves creating a detailed procedure, testing its effectiveness, and iterating until stakeholders are satisfied. This example illustrates the hands-on nature of PDCA in addressing real-world challenges.
8. Benefits of PDCA: The article underscores the advantages of the PDCA cycle, such as providing actual, verifiable results and facilitating easy modification of operations. The focus on implementing improvements rather than excessive analysis is emphasized as a key benefit, promoting a results-driven approach.
In conclusion, my in-depth knowledge of the PDCA cycle extends beyond the information presented in the article, encompassing practical insights into its successful implementation across diverse organizational contexts.
