Sales turnover is costing companies millions of dollars each year. Four out of ten sales people hired each year will fail to meet expectations and leave their jobs. Each mis-hire costs a company 5x the annual salary of a sales person. Topgrading, by Dr. Brad Smart, has sold over 125,000 copies since its release in 1999. Topgrading is the definitive book for executives who want to hire, retain, and develop top talent. Now Dr. Smart has teamed up with Greg Alexander who uses Topgrading to convert average sales forces into world class performers.
