Software Requirements with Use Cases

This 2-day course provides an approach to producing software requirements using use cases as the core technique. Topics covered include modelling use cases and also the process of identifying, outlining, prioritising, and detailing use case reports.

Description

Use cases are a popular technique for gathering, analysing and managing software requirements.

While use cases provide a central theme for the course, it is also shown that use cases by themselves do not constitute a complete set of software requirements. As such, the course also includes other practices and techniques commonly used with or incorporated into use cases, such as domain models, business rules, data requirements, user interface specifications, and supplementary requirements. Furthermore, the course provides insight into how use cases form the basis for use case realisation and test case preparation.

The ‘Software Requirements with Use Cases’ course is delivered by seasoned Equinox consultant practitioners who apply the techniques and practices presented in this course on a daily basis.
