About this Course

In this one-day 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.

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.

This course takes a highly practical approach to the challenge.
