Integrated Supply Chain Management (ISCM) involves the linking of suppliers and customers with the internal business processes of an organization. ISCM solutions allow organizations to automate workflows concerning the execution and analysis of planning, sourcing, making, delivering, returns handling, and maintenance, to name but a few. Many of today’s ISCM systems use primarily Web technology as the supporting infrastructure. Undoubtedly, the electronic (Internet-based) ISCM systems deliver the enterprises with a competitive advantage by opening up opportunities to streamline processes, reduce costs, increase customer patronage, and enable thorough planning abilities. However, there has been significant customer backlash concerning the inability of software vendors to deliver easy integration and promised functionality. Although various researchers have suggested strategies to overcome some of the failures in operating ISCM systems, there appears to be a lacunae in terms of architectural investigations in the analysis stage. The methodology proposed in this chapter seeks to resolve these gaps and provides a fundamental framework for analyzing ISCM systems.
