MWITA-OXO-2026-012 · Evidence C · P1
Employees reported that full self-checkout still required service comparable to staffed checkout, while semi-self-checkout, where customers only pay, appeared more effective at reducing checkout-worker stress.
What this does not establish
One Japanese store and its checkout configuration cannot support a general labor-productivity or headcount-reduction claim.
Counterevidence & uncertainty
Technology intended to remove cashier work generated assistance, monitoring and conflict-management tasks; the less automated semi-self model was perceived as less stressful.
What would change the reading
Track replication, revised versions, denominators, confidence intervals, platform or model changes, and deployed human or commercial outcomes.
