The Shewhart cycle is also known as what?

The Shewhart cycle is widely recognized as the Plan-Do-Check-Act (PDCA) cycle, which serves as a fundamental model for continuous process improvement. Each phase of the cycle contributes to identifying problems, implementing solutions, and refining processes.

In the 'Plan' phase, objectives and processes necessary to deliver results in accordance with the expected output are established. The 'Do' phase involves implementing the plan on a small scale to test its potential effectiveness. During the 'Check' phase, the results of the implementation are monitored and evaluated against the expected outcomes to identify any discrepancies. Finally, in the 'Act' phase, actions are taken based on the results of the 'Check' phase to improve the process, standardize the successful aspects, or modify the plan accordingly.

This cyclical approach allows for iterative improvement and is foundational in various disciplines, including quality management and systems engineering. In contrast, the other options provided do not accurately represent the Shewhart cycle or its established terminology, making them less suitable as a response to the question.
