Enterprise SOA Roadmap
Enterprise SOA is the backbone of future business processes that are being developed today. But how can you achieve visible, meaningful results, quickly? What information can you use today to convince the decision-makers in your organization? Should you start with business functionality, or is it better to first set up the technical prerequisites with
SAP NetWeaver?
The answers to these questions can be elusive, which is why this book leverages several hundred existing projects as the basis for showing you how other enterprises have handled the rollout of enterprise SOA. The authors use prototypical roadmaps from selected industries together with proven recommendations and exclusive diagrams to help you pinpoint the best possible plan for your Enterprise SOA and avoid dangerous pitfalls in the implementation process. You'll benefit from numerous "lessons learned" at completed projects, enabling you to create your own plans in a structured manner, and ensuring that you get off to a running start with your own Enterprise SOA preparations.
