Abstract: Sequential configuration is a fundamental pattern that occurs when integrating systems that span domains and levels of abstraction. This task requires the integration of heterogeneous autonomous information systems, processes, and applications. We propose an extensible system for correlating sequential configurations across loosely-coupled systems. Our framework defines fundamental abstractions and interfaces that enable the implementation of domain-specific models. We build upon our framework to provide a suite of tools to support applications that manage the configuration lifecycle. Our implemented prototype application integrates the processes, tools, and data involved in the first two stages of the IT outsourced services contract lifecycle.

Keywords: outsourcing; service provisioning; enterprise systems; contract lifecycle; sequential configuration; loosely-coupled systems; information technology; IT services; abstractions; interfaces; domain-specific models.
