  There is some ambiguity of what agile means in both research and practice.
Authors have suggested a diversity of different definitions, through which it
is difficult to interpret what agile really is. The concept, however, exists in
its implementation through agile practices. In this vision paper, we argue that
adopting an agile approach boils down to being more responsive to change. To
support this claim, we relate agile principles, practices, the agile manifesto,
and our own experiences to this core definition. We envision that agile
transformations would be, and are, much easier using this definition and
contextualizing its implications.
