I know a guy that works at a company where the CEO will sell something to customers not knowing anything about the technical details, and then come back to the business and "make them do it".
But this Dutch company also makes use of some kinds of SWAT dev teams that help customers on the spot with issues, making sure the product lives up to the clients’ expectations, even if this means modifying a product delivered by the core dev teams. I.e.: if some feature was promised, but not yet part of the current release, the SWAT team might hack something quickly, often on the spot in the clients offices. Later on, such a hack might be replaced with a proper solution.
In one sense, great, I don’t want to bother about what a customer’s priorities are. But it turns out that only works if you TRUST the product team.
It was a nice company. Bosses had very limited direct power over the developers and designers, and rightfully so -- it's supposed to be a team of experts, after all.
