Developmental evaluation supports the process of innovation within an organization and in its activities. Initiatives that are innovative are often in a state of continuous development and adaptation, and they frequently unfold in a changing and unpredictable environment. This intentional effort to innovate is a kind of organizational exploration. The destination is often a notion rather than a crisp image, and the path forward may be unclear. Much is in flux: the framing of the issue can change, how the problem is conceptualized evolves and various approaches are likely to be tested. Adaptations are largely driven by new learning and by changes in participants, partners and context.
