The problem is NPS changes never reflect added or reduced value to the customer or user.
You have no idea, when it goes down, how it’s less valuable than before.
They accept NPS because it lets them have whatever agenda they want, detached from whatever actual value their teams are or aren’t delivering.
If you’re measuring what customers actually value, then things like NPS fall by the wayside.
But measuring actual value is specific to the product and often the customer. It’s not easy to measure.
Not some cheap off-the-shelf pseudo-science metric that has never proven to mean anything.
True design leaders don’t use crappy measures.
