History
In 1986 Ivar Jacobson first formulated textual, structural and visual modeling techniques for specifying use cases. In 1992 his co-authored book helped to popularize the technique for capturing functional requirements, especially in software development. Originally he used the terms usage scenarios and usage case – the latter being a direct translation of his Swedish term användningsfall – but found that neither of these terms sounded natural in English, and eventually he settled on use case. Since then, others have contributed to improving this technique, notably including Alistair Cockburn.
In 2011, Ivar Jacobson published an update to use cases called Use Case 2.0, the intention being to incorporate many of his practical experiences of applying use cases, and to revamp the technique.
