Abstract
Many organizations manage and maintain a diverse portfolio of information system (IS) applications. The integration of these applications is often necessary to support broader enterprise-wide business solutions such as e-business, automated supply chain management (SCM), customer relationship management (CRM) and enterprise resource planning (ERP). Enterprise application integration (EAI) is one approach to IS application integration. The paper presents a case study of an integration project at Harmond Bank where an EAI approach was used to integrate the IS applications in its home loans division. The case-study highlights many of the management and architectural decisions that are pertinent to IS application integration projects, and lessons learned from the case are discussed.
