Abstract
These three methods are well-known Information system designing methods, Waterfall model, Prototyping, Iteration method. But all these methods have the same problem that gaps between business requests and developed systems cause many system troubles. To overcome these gaps there appeared a new approach from business sides. That is a combination of BPM (Business Process Management) and SOA (Service Oriented Architecture). In this report, I describe this new design method from a business side view, and consider its merit and demerit.
