In a Product Family, what percentage of the same processing steps are usually shared?

The correct answer is that in a Product Family, it is typically expected that at least 80% of the same processing steps are shared among the products. This concept is essential in Six Sigma and Lean methodologies, as it highlights the importance of process standardization and efficiency.

When products share a significant portion of their processing steps, it leads to a more streamlined production process, which can reduce costs and improve consistency in quality and delivery. By focusing on commonalities in processes, organizations can optimize their operations, minimize waste, and enhance their overall manufacturing flexibility.

In practice, having at least 80% of shared steps means that organizations can leverage existing procedures, training, equipment, and even workforce skills across multiple products. This not only enhances productivity but also supports quicker ramp-up times for new products, as processes are already established.

While options suggesting lower percentages of shared processing steps may seem plausible, they do not align with the general expectation for a well-established Product Family in terms of efficiency and effectiveness in Six Sigma practices. These lower percentages would indicate a lack of standardization that could lead to increased complexity and potential inefficiencies in operations.
