We've both been in this situation. You show up for your first flight and what do they tell you? They tell you, forget everything they taught you in training; I'm going to teach you how to fly this airplane, how this system really works. You know what that is? That is the collective expertise of the situation; that is, making systems that do not work like they're supposed to work, really work.
Imagine if we could capture that through formal systems instead of the rumour mill. That's what SMS does.
