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.

• Using Service-Oriented Architecture and Component-Based Development to Build Web Service Applications (Brown at al., 2002).

• Web‐service implementation methodology for SOA application (WSIM) (Lee et al., 2006; OASIS, 2005).

• Service Oriented Modeling Architecture (SOMA) (Arsanjani et al., 2008).

• Developing a Legacy to SOA Migration Method. (Reijnders et al., 2011).

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.
