Introduction Why SODDM? Wrapping old applications is not enough. Applications need to be specifically designed for SOA. Software development methods like Scrum do not cover services. Business alignment.

WISM Based on agile development methods Adapted them for creating services Phases: Requirements Analysis Design Implementation Testing Deployment

SOMA Based on best practises at IBM Risk driven Phases: Business modeling & solution management Identification Specification Realization Implementation Deployment/monitoring Management.

Conclusion SOA needs a design and development method in order to create services that align with the business. SODDM provides an agile based development method that is geared towards managing services and tight business alignment in order to implement a SOA architecture. SODDM is meant for large scale applications and large enterprises.
