Our assembler unloads it between inspection and packing, so the saved seconds would be scattered through work she already does.

Observe that whole sequence before buying a trial. Time spent waiting, preparing and clearing the fixture belongs in the comparison. Ask the assembler which task she could actually stop doing if unloading were automated.

Thank you, Gabriel; I was treating each unload as if it occupied a separate person, and I will ask her to walk us through an ordinary order before we define the pilot.

And let your colleague price the fixture work before calling it small again.

There may still be a useful handling improvement. Just leave room for the observation to point somewhere other than an arm purchase.
