The PSS design GuRu methodology: Guidelines and rules generation to enhance PSS detailed design

Manufacturers are often compelled to navigate the transition towards servitisation. In relation to this phenomenon, the present work focuses on design problems related to physical product enhancement when the addition of a service component is needed. A methodology generating the most suitable technical directions and design ideas to be followed during the integrated product-service system (PSS) design is provided. These design directions are deployed per the design for product service supportability approach on two different levels: Guidelines (non-company and PSS specific) and rules (derived through design for X (DfX) approaches) specific to a company and a particular solution. An application case in an Italian company operating in the heating, ventilation, air-conditioning and refrigeration market is conducted.
