In 1.5 years the order-fill ratio or refill rate, i.e. the availability of complete true-to-order kits on time for reassembly, rose from 30% to 90%. Over the same period of time, work-in-process was cut drastically, almost in half, going from 8,800 parts to 4,200 parts, due in particular to increased versatility and planning all WOs to meet the identified needs.
