Of course, I would have made the same mistake as Johnson. But it is always a good reminder of how differently people’s brains work.
By removing the price war, pricing their product at value. You now can compete on a more simple message of quality: "Our product is worth $10 more because X". The best part of this is...that's exactly what Walmart is actually doing. Walmart is actually rather sale-resistant and they frame it as a 'rollback' rather than X% off. Walmart's message is purely the regular price, not the value.
The issue you of course run into for JCP though, is in the interm, as the market changes, you need to throw a bunch quarters made up of that built up growth hacking debt of ever increasing sales in the trash. That just won't fly on Wall st.
What JCP really need is a reboot though, they are doomed either way due to their leases. Organizationally, I would be trying to get rid of those as fast as possible and get into outdoors small-medium retail. They have a great brand but have insanely expensive locations.
It's like if someone would have taken over Kodak at the turn of the century to go all-in on digital. It would have hurt the company in the short term and kicked against their core business but maybe they would have come out on the other side better off. Impossible to say if the scenario isn't allowed to happen.
His tenure coincides with the beginning of the decline of department stores in general, so you'd have to show that JCPenney fared uniquely worse to say that he ran it into the ground. It still exists, unlike Lord and Taylor and Sears. Doesn't seem to have fared much worse than Macy's, though I didn't do a ton of research here.
Department stores had already been declining for a long time before he came along, though.
The problem is it didn't translate into improved performance. The opposite actually. Because what customers say and what customers do aren't always the same thing. They may complain that there are too many coupons. But when given the choice they preferred using coupons.
So he got sacked and JC Penney went back to the old pricing scheme. By becoming even more risk-averse no one after him even tried to pull the company out of its death spiral. In hindsight the plan would never have succeeded because the customers who would have appreciated the simpler pricing had already left. The JCP shoppers at that time were coupon hunters who resented the changes. He ignored the existing customers while chasing ex-customers who didn't want to return.
