Chapter 2 Introducing PowerDesigner
Business Analysts define business requirements, which may be refined into technical requirements by Analysts and Designers. You will use a Requirements Model (RQM), which describes a project by listing and explaining precisely what features must be implemented during a development process, and who is responsible for them. These requirements can then be attached to any object in any of the other models in order to trace where, and how, they are met.
Business analysts can also define the high-level business process flows to describe existing and new systems, and can simulate business processes to reduce time and resource and increase revenue. You will use a Business Process Model (BPM), which represents your organization's processes in real business terms. You can use a BPM as a design tool to identify your business needs, organize them in a hierarchy, display your processes graphically, and then generate components in process languages such as BPEL4WS or Sybase Unwired Orchestrator.
