Chasing Stars The Myth of Talent and the Portability of Performance Boris Groysberg In the knowledge economy, many companies go to great lengths to lure star employees away from competitors in the belief that talented performers who change firms will bring their success with them. But in Chasing Stars, Harvard Business School professor Boris Groysberg reveals what a disastrous assumption this can be. After examining the careers of more than a thousand star analysts at Wall Street investment banks, he comes to a striking conclusion: star analysts who switch firms suffer an immediate and lasting decline in performance, their earlier excellence appearing to have depended heavily on their former firms' resources, organizational cultures, networks, and workforce. The book also examines how its findings apply to many other occupations, from general managers to football players. Offering profound insights into the fundamental nature of outstanding performance, Chasing Stars also provides practical guidance—to individuals on how to manage their careers strategically, and to companies on how to identify, develop, and keep talent.
