Stand next to the best person on the team for one shift. Watch their hands, not their mouth.

Expertise lives mostly in the hands and the timing, not in the explanation. Ask a very good person how they do it and you often get a simplified account, because the real method has become automatic and invisible to them. Watching them work for an hour gives you the sequence, the shortcuts, the small preparations nobody thinks to mention.

Arrange one shift beside the best person you have access to and say very little. Watch what they do before the hard part, not just during it. Write down three specifics afterwards while the memory is still sharp.
