JIRA is a bug tracking, issue tracking, and project management application. JIRA has been designed with a focus on task achievement, is instantly usable and is flexible to work with. It also offers a powerful Plugin architecture that allows us to write plugins that change the way things work or add entirely new functionalities. And by choosing Confluence as a Document Test repository and knowing the good integretion between this two application, it was an easy decision to choose JIRA as a Requirement Repository.
