Lead time Management
I am looking for insights on best practices for maintaining lead times. We experience very dramatic changes in business level that affects the lead time for many of our parts (primarily build-to-print items) as supplier capacity and utilization change. We are currently using a look back at actual deliveries and calculating the lead time at which 90% of orders were delivered. This works for parts with frequent deliveries, but may not be the best choice for items with few deliveries. Many of the suppliers do not have a good handle on their lead time, and are impacted by high order change rates, so asking them does not yield accurate data.
