Ask who gets trained and for which tasks, because one person starting a saved job isn't the same scope as shift cover changing tooling and handling an interrupted batch.
Who answers when those operators reach a recovery they aren't allowed to do? That person needs the relevant handover too, or the call just goes straight back to the supplier.
Have they said whether the training uses your actual kit trays, or another prepared demonstration? I'd want the people learning changeover to see the arrangement they will be changing.
