3.4. TIER 3: SOA AND SERVICES DEVELOPMENT LIFECYCLE TIER

The SOA and SDLC tier focuses on the processes that produce services for consumption by enterprise consumers. This chapter provides a brief overview, with more detailed coverage of SDLC governance following in Chapter 8. We break the SOA and Services SDLC into two sub-lifecycles: the provider side and the consumer side.

Achieving SOA value demands that services be consumed. Few organizations are mature with their consumer-side processes of their SDLC. SOA is about driving business transformation via consumption of reusable services, with the emphasis on consumption. No consumption of services effectively limits any potential value of SOA. Exhibit 3.10 depicts a generic view of an SOA/Services SDLC.
