A/B testing has been the de-facto standard for testing website features and customer base management for any internet company and it has widespread to other industries including telco. However the latter face the challenge of managing physical channels (eg stores) for which it is not possible to leverage A/B testing. This makes footprint management (ie closing/opening) an hard problem to tackle in a quantitative and scalable way. In this work we present a data driven approach to help retail managers to deal with it.
