“…Third, the integration of this work with a BS composition approach so that the requirements determination leads to a specific solution in terms of which business and software services will be used to realize the required BS functional and non-functional goals. Finally, the further integration of the work with a BS design framework [20] so that a specific toolset is offered to the designer, assisting him during the design of a specific BS.…”

Organizations now resort to service-orientation as it enables them to quickly create and offer new business services (BSs) or optimize existing ones. In many cases, organizations must cooperate to offer such services so as to concentrate only on their core business. An initial phase to the design of a novel BS concerns the determination of the BS's functional and non-functional requirements. The respective research approaches exploit goal models to specify and elicit such requirements. However, while it is easy to reach an agreement for the functional requirements, this is not true for the non-functional ones. First, as the involved stakeholders may have different requirements and expertise level for particular non-functional aspects. Second, as a BS's non-functional performance is critical for distinguishing among functionally-equivalent BSs of other competing organizations. Thus, the stakeholders must negotiate over the BS's nonfunctional requirements. However, such a negotiation may take considerable time and needs the active stakeholder involvement in terms of alternative offers for the conflicting requirements. To this end, this paper proposes a broker-based BS negotiation framework that can automatically determine the non-functional requirements of the required BS. This framework takes as input a functional goal model as well as the stakeholder requirements in terms of utility functions on the non-functional performance of the required BS functional goal and its sub-goals, and can propose an overall solution that is balanced and consistent across the goal model levels and satisfies as much as possible all the stakeholders.

Abstract. In this chapter we introduce and illustrate a systematic and rigorous approach for the elicitation and the modelling of assurance requirements inherent to business services offered by a service system. The approach is based on guidelines provided by the ISO 15504 norm, which is applicable for the assessment of any type of process in order to check its compliance against assurance requirements. We explain how 15504 can be applied in the context of business services with the support provided by goal-oriented requirements engineering techniques like i*. Its use is illustrated through the handling of an excerpt of a real case from the construction sector complemented with expertise developed in IT service level management. While this chapter is focusing on the capture of business requirements and their transformation into a business oriented solution, we also briefly explain how this business view is part of a more complete methodology also encompassing the service value and the service software views associated with a service system.
