"Process Monitoring of Impacts is a method for steering
interventions (projects or programs). “Steering” means influencing the behavior of involved actors so they follow a desired course, either by staying focused on achieving specified objectives or, in the case of changing contextual conditions, modifying implementation strategies. It is essentially about identifying processes considered relevant for the achievement of results or impacts and then monitoring whether these processes are valid and actually take place."-Systems Concepts in Action, Chapter 5
