“Collaborative      Sourcing”: The value driven by the average sourcing team over the last      decade has, in many cases, been significant and transformative. But,      competitive forces at play in a rapidly changing business environment      require that many tried and true strategies must be enhanced if they are      to retain their impact. Ardent Partners has recently published a report      that looks at how a collaborative sourcing approach can help sourcing      teams deliver greater value to the enterprise. The report was sponsored by      Ariba.
