The Deming Cycle, also known as the PDCA cycle (Plan-Do-Check-Act), is a continuous improvement model that emphasizes a structured approach to problem-solving and process improvement. It consists of four key components:

1. **Plan** - Identify a goal or a specific improvement to be made and create a plan to achieve it.

2. **Do** - Implement the plan and execute the process to see the results of the change or improvement.

3. **Check** - Evaluate the results of the implementation to determine if the desired outcomes were achieved. This is often where measurements and data analysis occur to assess effectiveness.

4. **Act** - Make adjustments based on what was learned in the Check phase, either standardizing the successful change or starting the cycle again for further refinements.

"Assess" is not part of the standard terminology used in the Deming Cycle; instead, the equivalent term in the cycle is "Check." Thus, identifying "Assess" as not a component of the Deming Cycle is correct, as it highlights the importance of using the precise terminology associated with established methods for clarity and effective communication in a safety management context.
