Interviews collect narrative information on a theme from persons relevant to a project or program through a more or less structured discussion led by the interviewer. They are not usually used to provide data for a logframe or Performance Monitoring Plan, but they are very useful for formative M&E purposes.

Respondents are selected for their first-hand knowledge about a topic of interest. These persons may be for example community leaders, party officials at local or national level, external experts such as academics or journalists, representatives of government, of international NGOs, and similar.
