Evaluations are an essential part of human sharing accountability. And working with a good evaluator is a fantastic opportunity for learning and improving. However, often evaluations turned into painful confrontational accountability exercises, that leaves nobody satisfied and changes nothing. This week's guest on communitarian is Michael Patton who together with Lars Peter Nissen discusses what evaluations can do for the humanitarian sector, what they are and what they are not (an audit) and how to build trust with your clients while at the same time satisfying the need for accountability.
