CEB's research found that the most effective approach in B2B sales to diverse customer teams is to target the "Challenger Customer", also known as the "Mobilizer", who is someone who challenges the status quo, is skeptical, and is supplier agnostic. This person has the credibility to inspire change within the team and help build consensus in a dysfunctional buying group. Sales and marketing teams need to collaborate in new ways to find the Challenger Customer and win the sale.
