Due to the distinctive nature of modern-day service-oriented architectures, using case studies is an effective way of conveying the topics covered by this book. Though purely fictional, the examples derived from these case studies raise common issues and problems faced by typical IT departments.
This chapter provides background information for two separate organizations. The first is RailCo Ltd., a mid-size company with a modest IT staff. The second, Transit Line Systems Inc. (TLS), is a larger corporation with multiple IT departments managing enterprise-level solutions. Though treated as separate case studies, these companies also have a business relationship.
