Best Buy has taken the first step in their persona-centric model. According to the Wall Stree Journal’s Analyzing Customers, Best Buy Decides Not All Are Welcome, the sales associates have received training to briefly interview customers to determine if they are a Barry, Jill, or Ray Buzz.
In an effort to keep their store relevant in an increasingly e-commerce industry, Best Buy is also reducing rebates, promotions, and sales. Others may disagree, though I commend them in that decision.
