Assessment of business value from services re-use on SOA-based e-business platform

The top drivers for SOA adoption include the expectation of greater reuse in existing and newly-built Web services, business flexibility, simplification and speed of integration. So, in order to maximize the intended benefits of service-oriented architecture (SOA) implementation, organizations need to develop a well-articulated SOA quality strategy to promote trust and reuse. However, the shift to this strategy does not come easy and cheap. Building an effective SOA platform requires tight integration between new and existing product categories, and it may require large investments. For this reason, conventional investment valuation methods need to be combined with other modern techniques to reflect SOA's long-term strategic investment nature, the inherent uncertainty and the managerial discretion. Some emerging value-based analytical methodologies have started to be developed extensively under the umbrella concept of Business Value Analysis (BVA). Thus, in this paper, we apply modified CVP/BEP method developed under the BVA umbrella for the evaluation of SOA projects, in particular for the services reuse related.
