In procurement planning, when is lead time most critical?

• A. When demand is unpredictable and lead times are long, orders must be placed earlier.
• B. When demand is predictable and lead times are short.
• C. Lead time is irrelevant for perishables.
• D. Only emergency purchases are affected by lead time.

Answer: (A)

Lead time risk in procurement rises when demand is uncertain and lead times are long, so you must place orders earlier to build a buffer against delays and variability. When demand can swing unpredictably, forecasting accuracy is lower, and long lead times mean you can’t wait to see actual demand before committing to delivery. Ordering earlier ensures you have stock on hand or in transit to cover the gap between when a need is identified and when the goods arrive, reducing the chance of stockouts or expedited purchases. If demand is predictable and lead times are short, you can time orders more precisely to align with known needs, minimizing safety stock and inventory carrying costs. Lead time isn’t irrelevant in any case—perishables require timely delivery to avoid spoilage, and even routine purchases are affected by how long it takes to receive goods. Emergencies do show how lead time matters, but the planning benefit is greatest when you anticipate variability with long lead times, not only in emergency situations.
