Service identification requirements for enterprise information systems.

Abstract

Identifying services is one of the most important step in developing service-oriented business systems. Existing service identification methods still have some shortcomings, e.g. unrepeatable approach, inapplicable to all enterprise information systems and unadaptable to business factor change. Some approaches focus on fixed cases or certain types of organizations neglecting the change of involvement and operation of the enterprise systems, which have limited value to apply to a broad range of real-life business cases In this paper, we investigate requirements of service identification from different types of information systems, from single systems to collaborative systems, from closed systems to open systems. The research is important for providing a solid foundation for further identifying services for developing different service-oriented systems
