Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Decoupling points
DDMRP methodology decouples demand from supply using decoupling points and manages inventory with buffer levels and zones. Option B (Decoupling points) is correct because they are strategic locations where inventory buffers are placed to reduce dependencies. Option C (Buffer levels and zones) is correct because DDMRP uses colored zones (red, yellow, green) to manage replenishment. Option A (Lead time offsetting) is incorrect; in DDMRP, lead time impacts buffer sizing but is not a core element. Option D (Safety stock levels) is incorrect; safety stock is a traditional MRP concept, while DDMRP uses dynamically adjusted buffers. Option E (Reorder point calculation) is also traditional; DDMRP uses buffer status and zones instead of reorder points.
