In software development, agile (sometimes written Agile) practices involve discovering requirements and developing solutions through the collaborative effort of self-organizing and cross-functional teams and their customer(s)/end user(s). It advocates adaptive planning, evolutionary development, early delivery, and continual improvement, and it encourages flexible responses to change.[further explanation needed]
It was popularized by the Manifesto for Agile Software Development.The values and principles espoused in this manifesto were derived from and underpin a broad range of software development frameworks, including Scrum and Kanban.
While there is much anecdotal evidence that adopting agile practices and values improves the agility of software professionals, teams and organizations, the empirical evidence is mixed and hard to find.
