1. The Value-Added Perspective on Quality
A customer-based perspective on quality that is utilized by services, manufacturing, and public sector organizations involves the concept of value.
Involves a subjective assessment of the efficacy of every step of the process for the customer.
A value-added activity can be pinpointed by asking, “would this activity matter to the customer?”
