The starting point of
any Test Case definition activity is the To-Be Business Process from which
Business Scenario are in turn inferred. There usually are 2 mains types of
business scenario :
Unit scenario
: describing the process at the task level
End-to-End scenario
: describing a complete business process, and made of a chain of unit
scenario.
The unit scenario describes the basic
business process activities and the work steps involved in the proposed
To-Be system thus providing the basis for mapping to SAP and later for
determining the necessary customizing of SAP and extension or modifications
that will also need to be developed.
The End to End Scenarios contain the link
of unit scenarios in order to reflect a complete picture of the business
transactions in the new system. This integration is important for ensuring
the coherence of the total design/architecture of the future system and will
be the basis for building the end to end test cases to validate it.
Both types of scenario must be created and
validate with the end-user and the business process owners.
