Following general stages in SOA delivery lifecycle are recognized
- service-oriented analysis
- service-oriented design
- service development
- service testing
- service deployment
- service administration
Top-down approach[edit]
- promotes the formal definition of corporate business models prior to modeling service boundaries
- can result in the highest quality level of SOA
- it also imposes a significant volume of up-front analysis work
Bottom-up approach[edit]
- delivery of application services on an "as needed" basis
- is easy to follow
- does not result in the advancement of service-orientation or process-enabled SOA
Agile approach[edit]
- meet in the middle
- on-going analysis is supported, while still allowing the immediate delivery of services
- as analysis progresses, existing services are revisited and revised as required
Service-oriented design (steps)[edit]
- compose SOA (define service layers,position core standards, choose SOA extensions)
- design entity-centric business services
- design application services
- design task-centric services
- design service-oriented business process
