A Product Family is characterized by their shared processing steps. What percentage of similar processing steps do they usually share?

A Product Family is defined by the commonalities in their processing steps, so when considering what percentage of similar processing steps they typically share, the threshold of at least 80% represents a significant level of similarity necessary to categorize different products together meaningfully. This high percentage ensures that variations among products within the family are minimal and that the benefits of shared processes—such as efficiencies in production, reduced changeover times, and improved quality control—are maximized.

This level of similarity allows organizations to streamline operations, as a greater degree of uniformity in processing means less complexity in managing the production of different products. It is important for the classification to reflect a substantial degree of overlap, as anything less could hinder the intended efficiencies, making the alignment of products within the family less effective.
