Evaluations of humanitarian interventions can broadly be divided into two categories: process and impact. While a process evaluation seeks to examine how the intervention was delivered and if the conduct or context influenced the outcome, an impact evaluation seeks to understand the causality between the intervention and the “positive and negative, primary and secondary long-term effects produced …, directly or indirectly, intended or unintended” (OECD-DAC 2010), in short, the impact. In my experience, this is the more commonly requested type of evaluation, particularly from, and to reassure, donors, who above all want to see and share tangible results.
