From 2014 impact will play a role in the allocation of research funding to UK universities through the Research Excellence Framework (REF). This presents universities with a new challenge: how best to capture research results and construct submissions to the REF. RAND Europe and Ranmore Consulting Group have developed ImpactFinder, an analysis and advice package to help senior research leaders determine how best to identify research with the greatest impact and present it to the REF panels. This brochure explains how ImpactFinder works and how universities can benefit from using it.
