What are the upcoming challenges in impact management?

In this chapter, the authors would like to highlight few essential point about impact management approaches and theories addressing three critical issues. The first one regards the evaluative object and the distinctions between impact models dedicated to organizations and those dedicated to projects/activities. The second issue concerns the relationship between impact schemes and sustainability metrics, with a focus on the overlapped, blurred, and frequently confused bounda-ries, as well as their developmental trajectory. Finally, the third issue concerns the various evolutionary stages of social and environmental impact, as well as the asso-ciated developmental trajectories and consequences at the implementation level. These three issues represent future lines of academic research and experimental ground for action-research projects.
