The aim is to embed an end-to-end data driven approach to cleint engagement across all sales lines based on a prototype methodology that has undergone 4 iterations with significant user-led enhancements over 2 years in a pilot business unit. The framework aggregates and collates data across a wide range of sources, integrates and delivers sales focussed insight back to end users. It uses both standard analytics models as well as innovateive sales expertise codification to rank clients for 'next best customer' selection. Results consistently show that the data-driven approach delivers 4x the average lead conversion rate for traditional approaches within a sales environment and that 80% of new business opportunities come from clients and offerinsg that lie outside traditional 'hunting' approaches.
