Deming Cycle – Plan, Do, Check, Act

Other types of system change lifecycles exist for HFE activities that are associated more with operations than with design.

The Deming cycle, also known as the PDCA cycle (Plan, Do, Check, Act), is a framework for continuous improvement and quality management. It was developed by Dr. W. Edwards Deming, a statistician, and quality control expert who is credited with helping Japan rebuild its manufacturing industry after World War II.

The four steps of the Deming cycle are:

  1. Plan: Define the problem, establish objectives, and develop a plan for improvement.
  2. Do: Implement the plan on a small scale, gather data, and document the process.
  3. Check: Analyze the data and evaluate the results of the implementation.
  4. Act: If the results are satisfactory, standardise the process and implement it on a larger scale. If not, refine the plan and start the cycle again.

The Deming cycle can be a useful methodology for organisational change because it emphasises a systematic approach to problem-solving and continuous improvement. By following this cycle, organizations can identify areas for improvement, test potential solutions, and make data-driven decisions to implement changes that can improve system design and development. The iterative nature of the cycle allows for ongoing refinement and adaptation, ensuring that the organisation is always striving to improve and evolve.

In the area of organisational change, both the Deming cycle and HFE can be used to improve the effectiveness of the change process. For example, when implementing organisational changes, the Deming cycle can be used to plan and execute the change, check the results, and act on the findings to continuously improve the change process. At the same time, HFE principles can be applied to ensure that the changes are designed to be compatible with the human capabilities and limitations, leading to better adoption and implementation of the changes.
