Start with the order path
Follow one order from guest to server, counter, KOT and final bill. Mark every point where a person has to retype or verbally repeat information.
Use one source of order context
Table, item, modifier and status should travel together. A kitchen team should not have to reconstruct intent from chat messages or handwriting.
Review exceptions
At closing, sample corrected, cancelled and delayed orders. They reveal broken hand-offs faster than a sales total.
