Introduction
• Service Oriented Architecture
Benefits
• Loose coupling
• Reusability
• Composability
• Enterprise collaboration
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.
