Barbara Bund, a senior lecturer at the MIT Sloan School of Management, tells the story of a group of engineers at Quaker State who were invited to observe consumer focus groups discussing the company's motor oil. "This one engineer was sitting in the backroom watching a group in which not one single person understood the difference between synthetic oil and nonsynthetic oil," Bund says. "He walked out of there and said, ‘We've got to get smarter focus groups.'"
