Leveraging service oriented programming paradigm would significantly affect the way people build software systems. However, to achieve this goal a solid software design methodology should be grounded on proper mathematical foundations, specific service-oriented principles, concepts and patterns. This paper contributes to the above goal proposing a lightweight, but complete, mathematical framewo...

nowadays a growing number of implementing informationtechnology service management (itsm) frameworks proves the trends toimprove the it services and processes in organizations. in order toimplement an itsm projects successfully in an organization, it isessential to select a suitable itsm solution. evaluation and selection ofthe itsm software packages is complicated and time consuming decisionma...

This paper explores the contribution of systems modeling to the design and analysis of viability in service systems. We apply a modeling framework called SEAM (Systemic Enterprise Architecture Method) to gain an understanding of how a service system maintains its identity and remains viable in its environment. SEAM embodies theoretical insights from systems science and organizational cybernetic...

The evolution of service science or Service Science, Management and Engineering – SSME, provides us with a platform to critically review the area of service design. The drivers for this include the lack of cross-disciplinary writing on service design, the limitations of the treatment of service design as an extension of product design and the dominance of B2C and neglect of B2B design. Three pe...

The " Service System " concept has rapidly emerged as a foundational concept in service science as the appropriate abstraction for describing how interconnected sets of services integrate the " value network " in some domain (Maglio et al, 2006; Spohrer, et al 2007). But the novelty and breadth that makes the service system an important idea also makes it challenging to teach. In this paper I d...

Service-oriented design supports system evolution and encourages reuse and modularization. A key ingredient of service orientation is the ability to substitute one service by another without reconfiguring the overall system. This chapter aims to give an overview of the state of the art and open challenges in the area of service substitution. Thereby, we restrict ourselves to changes of the serv...
