Not to be pessimistic, but this is also a somewhat common strategy to test how shitty you can make something. Basically, intentionally make things worse to test the impact on revenue. If profits don’t drop keep it that way. If the bottom line starts going down, slowly increase the quality again until they stabilize. It’s likely that changes were not reversed, they were just improved over the trash they made them for awhile. Chipotle has mastered this process. Raise prices, reduce quality, raise quality slightly but not to previous benchmark, repeat.
Yes, good point.
