The fraud department of UK building society Nationwide invested in SAS in 2008, initially to produce regular management information reports (which are now automated). This is how SAS came to be used as a strategic fraud detection system, which today has an 11-strong fraud analytics team at Nationwide using projects that include Base SAS, SAS Enterprise Guide, SAS Enterprise Miner and SAS Enterprise Business Intelligence Server. Through SAS, Nationwide managed to reduce its fraud losses by 75%. However, although reducing fraud was the main aim of Nationwide's association with SAS, it also wanted to improve its IT capabilities. One challenge was to monitor payments through the UK's Chaps system (which offers same-day sterling fund transfers). SAS monitors outbound Chaps payments every 30 minutes, producing an Excel report that auto-uploads to a shared server, which is sent to the investigation team.
