- VA desired to strengthen VHA’s IT capabilities by:
- Increasing organizational agility: reducing IT burdens by breaking down departmental silos, and decoupling services from their consumers.
- Improving Control: Through an architecture to give better control to update processes with little impact on other systems and costs.
- Enhance ROI: By reuse of services and eliminate similar development efforts.
- Enforcing collaboration across all competing organizations in order to establish a common set of principles for enterprise-wide SOA implementation
- Organized a robust set of subject matter experts and stakeholders from across the VHA enterprise
- Identified and documented all known services within VistA. Services will now be cataloged by service type to understand where overlapping services exist
- Implemented a common architecture to include a service bus to manage the services
- Developed and implemented governance plan
- All VistA services were documented and cataloged, including the implementation of a common architecture:
- Enables the organization to respond quickly to new business imperatives, develop distinctive new capabilities and leverage existing services for true responsiveness
- Promotes reuse of existing assets to increase efficiency and thus optimize application development costs with organizational flexibility and supports the building of next-generation solutions
- Provides data confidentiality and integrity through the use of encryption
