SOA as an architectural style is maturing, the levels of that maturity becomes visible with the validations performed on the project itself. Throughout the lifecycle of an SOA project, which IBM advocates as MADM-G, Model, Assemble, Deploy, Manage and Govern, this validation mechanism plays a crucial role. Modeling a business is usually a starting point for an SOA initiative, at this point the main aspects considered are the existing business process and how to optimize it, the points of agility and flexibility to accommodate changes in business, and this is where the visionary aspect of a business analyst comes into place. To foresee what kind of changes could happen in a reasonably foreseeable future, this would be usually in alignment with what the enterprise has plans for in the near future. The validation starts here; has the modeling phase covered the above aspects? During the assemble phase the architect and the analyst sit together to workout the agility and flexibility aspects when the optimized business process model has to be given ‘the IT’ life. How flexible and agile is the IT infrastructure to meet the business goals, is the architecture going to deliver that requirement, similar validations occur in the phase of Deploy and Manage phases.
For SOA to mature and materialize, the mechanism that drives SOA should mature. Just like CIO, Project Managers, Business Analysts, Architects are investments to a project so would be the mechanism that would drive and validate SOA throughout the lifecycle.
The underlying concept of SOA Governance that lays down ‘who’, ‘does what’, ‘how’, and ‘how to measure them’ throughout the lifecycle should drive SOA initiative than control it so that it is not looked up on as another approval mechanism to impede SOA. So SOA Governance would drive who does what and how, the measures of which would provide the input on maturing SOA.
Our showcase on SAP TechEd 2007 was how Websphere Service Registry and Repository in conjunction with SAP ESR works together, throughout the phases in an SOA project for enabling business process management.
