Operations

Scenario
Granite Materials is a building materials business in India shipping about 4m orders a year on ₹569 Cr of revenue.
It runs 2 distribution centres today. The supply chain team has proposed moving to 5.
Current economics per order:
- Line-haul: ₹61
- Last-mile: ₹139
- Average delivery time: 6 days
Under the proposed network:
- Each additional DC costs ₹12 Cr a year to run
- Last-mile falls to about ₹110 per order, because stock sits closer to customers
- Average delivery time falls to 5 days
- Marketing estimates faster delivery is worth roughly 4.9% of revenue in additional sales
The CFO is resisting on the grounds that fixed costs go up.
