Your biggest losses (minutes per shift)

BiggestPerformance (slow cycles, small stops)52 min
Availability (downtime)47 min
Quality (scrap & rework)7 min

Start with the biggest bucket. Availability losses respond to SMED and preventive maintenance; performance losses to small-stop tracking; quality losses to root-cause CAPA.
