Which of the following phases is NOT part of the Shewart product design cycle?

The Shewhart product design cycle, also known as the Shewhart cycle or the PDCA (Plan-Do-Check-Act) cycle, primarily focuses on the iterative process of designing and improving products based on data and continuous feedback. In this context, the phases involved typically center around designing the product, manufacturing it, and conducting market research to understand customer needs and product performance.

The implementation of training programs, while essential in a broader context of operational readiness and quality management, does not directly align with the specific phases of the Shewhart product design cycle. Training is a supportive activity that may assist in the execution of the strategies developed during the design cycle but is not categorized as a core phase of the cycle itself. Therefore, it is identified as the phase that does not belong in this specific framework.

The focus of the Shewhart cycle is on the developmental and operational aspects of the product lifecycle, making design, manufacturing, and market research pivotal components to this methodology. In contrast, training programs serve as a supplementary element that supports the broader goals of quality control and process improvement.
