The Experimenter's Inventory

A framework for thinking about the choices available to an agency, ministry or organisation that wants to experiment.

What is experimentation in policy or practice? And why is an experiment worth investing in?

What can an experiment tell you? And when or where might it fall short?

Answers to these questions are often complicated and unclear. This inventory provides an antidote: a catalogue of experiments of different shapes and sizes, and simple advice on the pros and cons of different designs.
