Integrated impact assessment (IIA) is the study of the full range of the consequences, immediate and long range, intended and unanticipated, of the introduction of a new technology, project, or program. IIA emphasizes the policy options available for dealing with the impacts. It incorporates the perspectives, interests, and values of the groups involved with and affected by the development being assessed. The process of directing attention to the potential effects of a planned intervention should result in better decisions being made concerning that intervention.
