SOA GOVERNANCE REQUIREMENTS VARY
BY SOA MATURITY
Another SOA governance misconception is that once you implement an
SOA governance initiative, you will not have to revisit it again. This is
patently false. SOA governance is fluid, evolving, and dynamic. SOA gover-
nance is a sustained and ongoing capability for your enterprise. The require-
ments for ongoing SOA governance will vary based on the organization and
the relative maturity of SOA in that organization. Exhibit 1.4 depicts an
SOA adoption lifecycle model that illustrates the fundamental phases of
SOA that an organization will proceed through on its journey to some SOA
steady state.
These SOA adoption phases in Exhibit 1.4 are described in detail
below:
&
SOA Inception. Initial SOA and Web services pilots and proof of con-
cepts (POC) occur here, where early learning and gaining SOA experi-
ence for a core team of practitioners are the project goals.
&
SOA Strategy and Planning. This phase often follows the SOA Incep-
tion phase and attempts to align all SOA activities under a coherent
strategy and roadmap for execution under the sponsorship and leader-
ship of a corporate executive. Our field experience shows that many
organizations proceed directly to the next phase, SOA Governance
Model Development, prior to developing an SOA strategy. We advise
doing them in parallel, starting with the SOA strategy and beginning
the SOA governance model development shortly thereafter.
