John Mulaney gets paid by prompt fondlers to tell jokes at a party. He spends 45 minutes telling them that they are idiots, which is nice.
Usually it’s the part of the org that is directly interacting with big, corporate customers. Those customers can and often do directly shape how a product works. It’s like a sales team, but focused on existing customers with big contracts (that might be expanded), rather than acquiring new customers.
But admittedly, this has just been my experience. I’m sure it’s probably not universally true.
