Improving Priority Lot Cycle Times

ISMI member companies defined two master goals for the 300 mm prime initiative (see [2]): 50% cycle time reduction and 30% cost reduction. Combining these conflicting goals into a holistic approach represents a major challenge. This paper outlines how this goal can be targeted for priority lots. Though only a small share of WIP is priority lots, the benefit of short priority lot cycle time can be very persuading and the impact on overall costs very significant.
