Description
Overview
Use Cases are increasingly becoming “the” way to document the functional requirements of an enterprise – both at business and at system level. Essentially, they can be seen as an exercise in prose writing and, as such, can be undermined by ambiguity, incompleteness and unsuitable language. It is unlikely that any practitioner will ever produce the “perfect” use case while under the sort of pressures we find on projects but it is important to understand what constitutes an effective one.

Overview
Use Cases are increasingly becoming “the” way to document the
functional requirements of an enterprise – both at business and at
system level. Essentially, they can be seen as an exercise in prose
writing and, as such, can be undermined by ambiguity,
incompleteness and unsuitable language. It is unlikely that any
practitioner will ever produce the “perfect” use case while under
the sort of pressures we find on projects but it is important to
understand what constitutes an effective one.
In this course, we discover the nature of use cases and how to
express them in such a way that, collectively, they provide a sound
channel for expressing a business system’s requirements to all
parties involved in its journey from requirement to
implementation.
