- “Pareto s 80/20 rule, as applied to the SDLC, is in the process of being drastically altered. In the past, approximately 20% of the SDLC was spent on analysis and design activities with the remaining 80% spent on systems development and implementation”
- “In this new paradigm, approximately 80% of the SDLC is spent on analysis and design activities with the remaining 20% spent on systems development and implementation”
- “We want to develop software by integration rather than code writing. The software market is rapidly moving in this direction; component-ware and related methodologies are maturing day by day.”
- “More recently, enterprise resource planning (ERP) solutions, such as SAP and Peoplesoft, which involve replacing existing systems with a suite of interconnected modular systems from a single vendor, were seen as the answer to systems integration (Davenport, 1998). However, organizations soon realized that no single ERP system could address all the requirements of an organization (Hong & Kim, 2002).”
- “With SOA, the issue of integration is no longer problematic so long as every system conforms to the SOA model and is able to offer its functionality through a set of defined services. That, unfortunately, is the point where SOA suffers the same adoption problems as Web services” [as industries have invested much on legacy systems and have to live with them]
