Contribution analysis: How did the program make a difference – or did it?

Contribution analysis is an evaluation method that was developed by John Mayne in the early 2000s to enable evaluators to produce rigorous impact analyses in the context of programs that cannot be evaluated using an experimental or quasi-experimental design. While the Science-Metrix Evaluation team has been conducting contribution analyses informally for a while now, the workshop conducted by Thomas Delahais (of Quadrant Conseil) for the SQEP annual conference in October 2017 inspired us to use this technique in a more rigorous, systematic and comprehensive way. This method appeared to us as perfectly suited to the kinds of evaluations we, and probably many of you, carry out—that is, evaluations of complex, multifaceted programs for which counterfactuals cannot easily be used. In this post, I’ll give a brief synopsis of the method and provide suggestions for further reading.
