Mistake 1: treating Dietary Table Coordination as a late layer
This workflow usually slips when dietary notes are stored in a separate file, when families are split without meal context, or when allergy handling is assumed instead of briefed. Teams often wait until the decorative or final-minute phase to solve a problem that is actually structural.
Mistake 2: splitting revisions from the live plan
The guest list owner, planner, and catering lead need one interpretation of tags, service timing, and how dietary guests are identified discreetly. Once that link breaks, accuracy drops fast and staff start improvising.
Mistake 3: finishing without a setup-ready version
A beautiful artifact is not enough if the venue team still has to guess where it goes, how it is read, or which version is final. The final plan should help catering know where special meals go without exposing private details more widely than necessary.
