There are different popular models for collaborative software requirements definition. In this article, Gojko Adzic, the author of Specification by Example, discusses some of them. Big specification workshops, like Product Backlog Refinement (PBR) workshops, with the entire team allows building a shared understanding and produce a set of examples that illustrate a feature. Smaller workshops that involve one developer, one tester, and one business analyst are called Three Amigos meeting. Teams where business users and stakeholders sit close by (and are readily available to answer questions) have great results with informal conversations. Instead of having big scheduled workshops, anyone who had a stake in a story would briefly meet before starting to implement it.
