About the Book

A service-oriented architecture is fundamental to many new IT applications, from Web 2.0 to social software and cloud-computing. Yet everything is a service: we can apply the same principles to every aspect of the service-oriented enterprise.

This book explores how enterprise architecture and viable services link together to create a simpler yet far more powerful view of the enterprise, as a dynamic, unified whole. The techniques described can be used in business transformation, workflow mapping, system design and much else besides, in every type of enterprise - including those in which there is little or no IT at all.

Topics covered include:

  • how to identify and describe the right delivery services, infrastructure services, management services and pervasive services you need for your enterprise
  • how to distinguish between services you can safely outsource, and services you need to keep in-house
  • how to enhance service quality, interdependence and completeness
  • how to pinpoint and map the information-flows you need for service-management and service-performance
  • how to construct function-models and service-models of your enterprise, as a base for service-mapping
  • how to use services to support agility and innovation across the entire enterprise

If you want to apply the full power of the service-oriented enterprise to your own business context, this is one book you'll definitely need.

The Tetradian Enterprise Architecture Series presents new developments on theory, principles and practice of enterprise architecture - moving beyond IT to the whole enterprise.
