In these early stages of PSS research, it is necessary to define a holistic problem definition for designing productservice systems (PSS). In this paper, the current industrial practice of the problem definition within PSS is analyzed and presented. This analysis has lent itself to a classification of the steps involved in the problem specification stage into developing the Customer Specification (what the customer wants) and the Customer Demand (how the customer wants it) stage. Also it summarizes the important parameters considered in the problem definition. These results help to identify methods required to solve the industrial problem definition of PSS.
