Ours is a little different because we have WHS run all label control conveyable and breakpack. Basically one team member is responsible for handing out labels to each team member as they need them.
We have a check out system setup. So say Joe Schmoe is pulling OOS he's gonna go to the label person and ask and the label control is going to check what the next location on the pick sequence, what zones that packing needs, what aisles are blocked. And then they have a signout system whether scanning your badge or something and sign the labels out to Joe.
You're also verifying that the team member is ACTUALLY picking the labels and not scanning and tossing them. Not cherrypicking good pulls out. You'd collect leftovers at the end of the day and partner with next shift label control over what they need.
Not complicated but a lot of detail oriented work that its important to stay on top of.
