Recent developments in the area of software service systems brought a new level of scale, complexity and pervasiveness to cope with. This has, in turn, changed the business model of companies engaged in the software industry and the way they present their services. Healthcare systems, as an example, transform services from a traditional professional- centric care model to model that is characterized as ‘pervasive healthcare’. Pervasive healthcare applies extramural networked healthcare systems with sensors and devices at the patients’ location, making the patient an active partner in the care process. These transformations of technologies and business models have brought a new breed of systems called Smart Service Networks (SSN). An SSN involves any number of devices, sensors and IT systems, and has diverse stakeholders, which together form a network in which resources are integrated and applied through interaction (Stroulia, 2010).
n SSN is a context-aware system, it can adapt and provide specific services to the user according to the context information received from data collected with sensors. Therefore, SSN must be able to clearly understand the significance of the context information conveyed from its environment. The quality of the context model determines the extent to which the SSN can offer services that fit the actual context, which in turn determines the usefulness of the offered services to the user. The quality of the context model depends on the quality of the collected context data (accuracy, timeliness, etc.). Low(er) data quality means low(er) model quality, which can lead to (more) off-topic service offerings. Off-topic service offerings can be useless to the user, and may even have negative value to the user.
SSN development projects operate in a multi- stakeholders context and potentially experience conflicts among functionality, risk and cost to meet the stakeholders’ requirements. This research focuses on trading-off functionality, risk and cost within SSN development. By defining the possible trade-off scenarios in SSN delivery projects, this research will provide a rational analysis to justify SSN design decisions that lead to achieving software systems with adequate functionality, minimum risk and reasonable cost.
