This document discusses managing requirements and collaboration in Jira using behavior-driven development (BDD). It outlines how BDD in Jira allows for formulation, automation, and discovery of requirements through examples mapped to scenarios. Examples of system behavior are documented using business terminology to create shared understanding. This living documentation is then automated and can be navigated. The document also discusses how Cucumber allows teams to deploy software 10 times per day through a model of independent microteams using BDD and test-driven development for 100% automated testing and a continuous integration/delivery pipeline.
