Johnson was trying to take JCP upmarket (not so much in price/quality as in type of customer) because he knew they were going to be completely squeezed out by the logistics capabilities of stores like Target. Unfortunately, that kind of process takes years and a lot of courage because you will alienate many, if not most, existing customers before new customers come.
But JCP did the worst thing: they stopped right after alienating their existing customers. I think my brother-in-law will be looking for a new job soon. I will have a great deal of respect for the new CEO if they can bring JCP back to their previous level of "glory" and maintain it.
