When I arrived at Liz Claiborne, in 2006, I wasn’t expecting to lead a major transformation. The board had hired me to make sense of a swollen portfolio of mainly wholesale brands—more than 45 in all—and everything suggested a “realignment” opportunity. But in my sixth month on the job, the business teams came back with news so bad that we had to issue earnings guidance below consensus by 65%. Mere tweaks wouldn’t save us; transformation was the only course.
