No full textThe globalization needs and the increased competition between all types of companies put an increased focus on service improvement. Services are mostly customized, intangible, knowledge-based, and one type of services, called here as People Processing Services (PPS), can have the direct participation of customers both as object being processed and as a co-producer. These characteristics of PPS make it difïŹcult to standardize processes, which contribute for generating non-value added activities, classiïŹed as wastes in the Lean Thinking knowledge area. This work aims to contribute to the waste classiïŹcation, proposing a clariïŹcation for the types of waste associated with People Processing Services, and further applying this classiïŹcation to a particular PPS case, the Hip Surgery Production Process of a Portuguese Public Hospital. It was observed that a large number of activities do not add value to the service and waiting is the most common waste.info:eu-repo/semantics/publishedVersio
