The early stage of service development primarily has two design phases: acquiring demands/constraints and determining delivering functions. The latter phase is significant in bridging the gap between design and implementation; as service providers in the IT industry have struggled in determining an appropriate combination of functions: IT-enabled functions and practitioners’ activities. This paper focuses on nonfunctional requirements (NFR); and quantifies the value of respective combination of service functions from NFR perspectives by clarifying the relationships between NFRs; qualities and functions. Case studies on educational services show that the approach will provide us with a basis for determining respective function priority.
