The Role of Service Oriented Architecture as an enabler for Enterprise Architecture.

Organisations are being challenged to ensure that IT delivers on business requirements, but more importantly to ensure that IT can provide greater differentiation and competitive advantage in the context of business, as opposed to the traditional supporting role that many IT professionals have become accustomed to. There needs to be a drastic change in the relationship between IT and business, in order to address the challenges that organisations are currently experiencing and will be experiencing in the future. This change can only be achieved when IT can demonstrate real business value to organisations. SOA, EA and the relationship between them provide a means to achieve the relationship between IT and business by providing a means of defining and implementing business capabilities. This research focused on investigating the guidelines that are needed for SOA to enable EA, in order to provide practical steps that organisations can use for the alignment of SOA and EA

The role of service-oriented architecture as an enabler for enterprise architecture

Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2011.The adoption of Enterprise Architecture (EA) methodologies within organizations is causing an interest in the methodologies and supporting technologies available. Service Oriented Architecture (SOA) supports EA in many facets. However, there is much suspension with regard to the relationship between EA and SOA within organizations as well as the guidelines that organisations should follow in order for SOA to enable EA. There are potential problems that may arise if this relationship between SOA and EA is not agreed to at the outset of implementing an EA. The purpose of this research is to investigate the guidelines that are needed for SOA to enable EA, in order to provide practical steps that organisations can use to begin aligning SOA and EA, ensuring that these initiatives are driven from a business perspective. A qualitative approach using a case study was used as a methodology for this research. The data collection was conducted using semi-structured interviews, and the guidelines that were derived were validated through a survey that was distributed to industry architecture practitioners. The contribution of this research was a set of guidelines that can be used for SOA to enable EA. Further research areas were highlighted, including investigating the mapping of the guidelines that were derived from this research, into the EA frameworks that exist such as TOGAF and ZACHMAN
