A Guide for Designing and Conducting In-Depth Interviews for Evaluation Input

This short guide defines In-Depth Interviews, explains their advantages and disadvantages and the steps involved in their application. 

"In-depth interviews are useful when you want detailed information about a person’s thoughts and behaviors or want to explore new issues in depth. Interviews are often used to provide context to other data (such as outcome data), offering a more complete picture of what happened in the program and why." (Boyce & Neale 2006 p3)
