Summary

Build a high-value dynamic enterprise by leveraging SOA and Business Process Management together!- A pragmatic, step-by-step tutorial: achieve breakthrough business flexibility by integrating enterprise architecture with modularized dynamic business processes.- Directly addresses BPM, one of the world's fastest-growing software markets- By Marc Fiammante, IBM's worldwide chief architect for SOA engagements: draws on his unsurpassed experience driving value from SOA and BPM Thousands of enterprises have adopted SOA based on its promise to help them respond more rapidly to changing business requirements by composing new solutions from existing business services. To deliver on this promise, however, companies need to integrate a solid Business Process Management (BPM) plan into their SOA initiatives. Dynamic SOA and BPM offers a pragmatic, efficient approach for doing so. Top IBM SOA architect Marc Fiammante walks readers step-by-step through integrating BPM and SOA, and using them together to build a more flexible, dynamic enterprise. Throughout, he emphasizes hands-on solutions based on his unsurpassed expertise supporting dozens of enterprise SOA implementations. Coverage includes:- Moving from simplified integration to dynamic processes.- Streamlining enterprise architecture to support BPM.- Implementing dynamic enterprise information and business processes.- Tooling for design and development in a dynamic enterprise.- Managing and monitoring a dynamic environment, and much more Practical from start to finish, Dynamic SOA and BPM squarely addresses two of the most critical challenges today's IT organizations face: implementing BPM as effectively as possible, and driving more value from their SOA investments.
