In this dissertation, the subject of Requirement Management (RM) as a performance measurement and development system is discussed. Public Private Partnerships (PPPs) in the educational environment and catering operations in the Finnish Defence Forces (FDF) are used as case examples. In addition, due to their relevance to the FDF, the author’s research describes New Service Development (NSD), sustainability and Critical Infrastructure Protection (CIP).

The dissertation contributes to current studies in the areas of RM, PPP and service science. The main objectives of this study are to research, analyse and assess how RM could be used as an NSD technique in PPPs. The results of this research establish a proposed development model for services in the PPP context.

The work contributes to the scientific discussion on the discipline of service science and NSD, introducing a cross-disciplinary study that combines currently separate areas in the field of service science. This research contributes scientific evidence showing that RM offers benefits as a managerial approach, and it shows how RM could be used as a technique in NSD during all lifecycle stages of a service. The results indicate that RM increases the opportunity to find, use and utilise key performance indicators in the search for efficiency and effectiveness in services.
