Ardent Instruments: Total Landed Cost and Source Award
Ardent Instruments buys a machined sensor housing at 240,000 units a year. Supplier A, the incumbent in Southeast Asia, quotes $12.40 per unit, 45-day lead time, a 5,000-unit minimum order, freight of $0.85 per unit, 7.5% duty on unit price, a 1.8% incoming defect rate, and net 30 terms. Supplier B, nearshore, quotes $15.10, 12-day lead time, no duty, freight of $0.35, 0.4% defects, and net 60 terms. Internal data put the cost of handling a defective unit at $8 regardless of source, inventory carrying cost at 25% a year, and the cost of capital at 8%. A quality escape that stops the line costs about $60,000 per event, and air freight to recover a late shipment runs $2.50 per unit. Purchasing has proposed consolidating 100% of volume with Supplier A to capture the price gap, arguing that freight and defects are already in the comparison. Engineering notes the housing is on the critical path of every product Ardent sells and that qualifying a new source takes 6-9 months.
1. Build the total landed cost comparison for both suppliers at current volume and state whether 100% award to Supplier A is justified.
Read the worked answer
Per unit landed cost:
| Element | Supplier A | Supplier B |
|---|---|---|
| Unit price | $12.40 | $15.10 |
| Duty | $0.93 (7.5%) | $0.00 |
| Freight | $0.85 | $0.35 |
| Defect handling (rate × $8) | $0.14 | $0.03 |
| Landed unit cost | $14.32 | $15.48 |
A is $1.16 per unit cheaper on landed cost - about $278,000 a year.
Now add the working-capital effect of lead time. A requires 45 days of pipeline (240,000 / 365 × 45 ≈ 29,600 units); B requires about 7,900. The extra 21,700 units tie up roughly $311,000, which at a 25% carrying rate costs about $78,000 a year - about $0.32 per unit. Payment terms favor B: 30 extra days on roughly $3.7M of annual spend is about $304,000 of float, worth roughly $24,000 a year at 8%.
Net: A still leads by about $175,000-200,000, or 5% of spend.
That gap does not justify a 100% award. Three $60,000 line-down events, or four air-freight recoveries on one month of volume (20,000 units × $2.50 = $50,000 each), erase it. A 45-day lead time with a 5,000-unit MOQ also means a demand miss cannot be corrected inside a quarter, and Ardent would hold zero responsiveness on a part that gates every product. The correct conclusion is that price advantage is real but thin, and it buys away all the flexibility.
2. What award split would you recommend, and how would you defend the split against the purchasing team's cost argument?
Read the worked answer
Recommend approximately 65% to Supplier A and 35% to Supplier B, with the split reviewed annually against delivered performance.
Defense of the split:
- The premium is smaller than it appears. The $175,000-200,000 gap is roughly 5% of category spend. Shifting to an 80/20 split costs in the region of $60,000-70,000 a year of that advantage while buying a live, exercised second source - cheap insurance for a part on the critical path of every product.
- The split must be large enough to be real. Below roughly 20-25% of volume, the alternate will not hold capacity, prioritize Ardent, or keep the tooling warm. A 35% share is defensible volume that a supplier will invest in; a 10% share is a paper qualification.
- Segment the risk by SKU. High-runner configurations with stable demand can carry more of Supplier A's 45-day lead time; new launches, spares, and custom variants should default to B's 12-day responsiveness. This links the award to the service each demand stream needs rather than an arbitrary percentage.
- Reward performance with volume, not with promises. Publish OTD and defect performance quarterly and move 5-10 points of share based on it; that turns the split into a management mechanism instead of a static compromise.
- Keep the negotiation alive with A. The credible threat of B taking 35% is worth more in the next price round than the $60,000 saved today.
If Ardent's volumes were stable, non-critical, and easily buffered, 100% A would be defensible; none of those conditions hold for this part.
3. What commercial terms should Ardent negotiate to protect itself under either supplier relationship?
Read the worked answer
Terms should allocate the risks that actually show up in this data - lead-time variability, quality escapes, and tooling access.
With Supplier A:
- Incoterms and duty control. Move from delivered to FOB so Ardent controls freight and can see duty exposure directly; duty is $223,000 a year and should be managed, not embedded.
- Lead-time and buffer commitments. Negotiate a vendor-managed or consignment buffer sized to cover 30 days of Ardent's demand, at A's carrying cost, in exchange for volume stability.
- Quality clause priced to the consequence. Chargeback should reflect the $60,000 line-stop cost, not just the unit price of the defective part, with an agreed containment protocol and 24-hour notification.
With Supplier B:
- Capacity reservation for at least the committed share, plus a firm 12-day lead time and a monthly capacity attestation.
- Volume-tiered pricing so the premium narrows as share grows, keeping the 14% gap from becoming permanent.
With both:
- Tooling ownership and transfer rights. Ardent owns the tooling, has documentation, and can move it within a defined notice period - this is what makes the threat of switching credible and the 9-12 month qualification less frightening.
- Price adjustment mechanism indexed to raw material and currency bands, with a collar, so a single input spike does not re-open the whole negotiation.
- Business continuity obligations: alternate-site plan, sub-tier visibility for critical castings, and a right to audit.
The test of any clause is whether it changes behaviour on a bad day, not whether it reads well in a contract.
