Wednesday 23 Dec 15
Krestine Mougaard from DTU Mechanical Engineering defends her PhD "A framework for conceptualisation of PSS solutions: On network-based development models" Monday 18th January from 13:00 - 16:00. The defence takes place in Building 101, meeting room s01.


Manufacturing companies are changing. More and more companies are taking greater responsibility for their products, expanding their customer relationships and providing new sets of service offerings. Increasing amounts of manufacturing companies are even switching from offering products (e.g. trucks) to offering performance (e.g. transport solutions). This transition is challenging, as it puts great demands on the company’s capabilities, both within the company and externally, in the company’s inter-organisational relationships. Taking greater responsibility of the product performance includes greater risk for the manufacturer, for which reason network capabilities become vital. Relationships to suppliers – and to suppliers´ suppliers – become essential factors in securing high-quality products, availability assurance, and suitable cost. Likewise, the customer relationship changes from a transactional to a relational interaction, in order to proactively meet the customer’s changing needs and establish to a continuous information flow, allowing preventive maintenance. Dissolving the sequential value chain into a collaborative ecosystem of stakeholders is a necessity, when offering Product/Service-System (PSS) solutions. Altered relationships and roles embracing the success of all involved stakeholders is one way (arguably, the only way) to a successful PSS.

Danish maritime suppliers are involuntarily facing this challenge; a lifeline of large order books from the Danish OSS shipyard at Lindø, near Odense, was cut with its closure in the early part of the second decade of the 2000’s. This forced suppliers to switch their focus from the shipyard to the shipowner. Thus, in one year the business changed from a product focus to an after-sales focus. This research project, which has been part of the Danish Innovation Consortium PROTEUS (PRoduct-service/system-Tools to Ensure User centred Services), was carried out at the Technical University of Denmark at the Section of Engineering Design and Product Development. The project’s aim was to investigate how to support the Danish maritime industry in this upheaval and change towards a new mode of business- and product development.

The research presented in this thesis is based on action-research, involving all ten companies involved in the PROTEUS consortium, plus a comparative case study of MAN PrimeServ Frederikshavn and Alfa Laval Aalborg.

The main contributions of the thesis are the following:

  • A comprehensive longitudinal empirical study across a whole industry sector, which was in transition from product- to product/service-system oriented business.
  • A theoretical foundation for PSS development, with a particular focus on network collaboration. In addition, a contribution to the theoretical knowledge about how the network paradigm “network oriented product development” and PSS theory can be assessed and developed.
  • An objectively derived normative framework of combined network-oriented PSS development, based on theoretical and empirical findings and verified in case companies.
    Three new PSS tools to support PSS conceptualisation.
  • Contributions to the PROTEUS Workbook series – communicating the results of the PROTEUS research consortium to both academics and industry practitioners.
