Cost Avoidance Score is a measure that helps to assess to what extent implemented cost reductions are realised. When companies embark on a cost reduction programme they need to establish whether actual savings have been made at the end of the programme.
This indicator will be included in my book: Key Performance Indicators - the 100 measures every manager needs to know, which contains an in-depth description of this KPI, as well as practical advice on data collection, calculations, target setting, and actual usage.
