"Reveals the roots of M&E, illustrating its evolution from academia into a burgeoning field of science across various contexts. The challenge practitioners face lies in the inconsistent terminology used for identical concepts among humanitarian organizations, hindering the growth of M&E through shared learning.

In doing so, it bridges the philosophical gap between novice and expert social researchers and provides a consolidated resource based on real-world experiences" --
