I remember back in my sys-admin days, when a vendor would come in, we would 'kidnap' the devs/engineers and keep them in our office, while he C-levels/Directors spent time 'discussing business'.

At the same time we were giving the devs/engineers a taste of what the requirements should REALLY be, or what the problems REALLY were. That gave them a far better idea of what our pain-points were.

It happened that devs/engineers, while in the presence of theirs and the customers' C-levels/Directors, they only smiled, nodded and agreed, which is kinda dangerous as they were forced to agree on insane, intangible, and unfeasible requirements.
