Thus, a strategy should not offer tactical or small-scale
solutions; it should provide a sustainable service evolution agenda that can endure unwelcome
events and ensure business continuity. The strategy should contribute the following aspects to the
service-oriented life cycle initiative:
??? Proactive approaches to address unforeseen events and guarantee business stability
??? Strategic and comprehensive road maps that offer alternatives and encourage business
agility
??? Reachable, measurable, and realistic milestones and goals that can be fulfilled within
allocated budgets and accomplished on time
34 Ch. 2 Service-Oriented Life Cycle Model
GOVERNANCE. The service-oriented development life cycle should be overseen by a governance
organization that is both engaged in supervision and also devises a development methodology
that offers service-oriented architecture (SOA) disciplines, best practices, standards, and policies.
Moreover, establishing a central governance entity is a prerequisite to service life cycle success.
This organization should be driven by SOA practitioners who clearly understand the processes
that help services thrive and who offer business and technological direction.
STRUCTURE. The service life cycle must have a flexible structure that can enable effective
service management. Life cycle structure means the framework in which services are constructed,
qualified, and operated in production environments.
