You can use business process diagrams to depict business
process flows.
Business process diagrams
A business process diagram depicts a directed flow
of activities that are specified by using a subset of Business Process
Modeling Notation (BPMN). Two types of process are supported: simple
and business-to-business processes.
Business rules
A business rule is a policy, constraint, or required
operation
that applies to a specific set of business conditions or dependencies.
An
example of a business rule for a bank is that a credit check is not
required
when an existing customer opens an account.
Business process diagrams
Business process diagramming is
a flexible requirements
definition technique. When getting started, it is best to use the
most simple process representation. Begin with a basic structure and
the clearly identifiable elements in the process. As your diagram
develops, add detail.
Business process elements
A business process diagram is a graphical representation
of a business process flow, which consists of a sequence of activity
elements and flow controls elements. Rational® Requirements Composer supports
a subset of elements from the core element set of Business Process
Modeling Notation (BPMN) standard.
