The book starts out with a high level overview of what technology allows today in terms of automating the orchestration of business services through executable business process models. It goes on to explain the architecture of the BPM tier (Hyper-Tier of IT). It actually describes a full-fledged Methodology to create Orchestrations with a real example. The methodology includes the estimate of the ROI of the projects being analyzed! After the Methodology Chapter, the authors get into substantial detail of the different components of an Orchestration Suite. Very Technical. Finally in the last chapter it all comes together from a technical perspective. It made me re-evaluate my judgement on BPM. I now know that Integration, Orchestration, Workflow need to be one and the same thing under a single process model. The book can be challenging for non-technical audiences after chapter 4. But Business People should not miss chapters 1 through 3.
