Lumen Learning: One Supplier, One Region, One Problem

Scenario

Lumen Learning makes edtech products for India. A single supplier provides a component representing ₹79 Cr of annual spend — around a third of bill-of-materials cost — and there is no qualified alternative.

Procurement has found a second source. It would cost about 8.7% more per unit and take 10 months to qualify. The incumbent has hinted that splitting the volume would cost the company its current pricing tier.

Risk modelling puts the chance of a material disruption at that supplier at roughly 8% a year, with an expected outage of 5 weeks. Contribution margin at risk is about ₹0.3 Cr a week if the line stops.

The alternative supplier's plant is in the same region as the incumbent's.

Your task

Advise the COO. Your answer should provide:

  1. Analysis — price the insurance. What does dual sourcing cost, and what expected loss does it avoid?
  2. Risks — including whether this second source actually reduces the risk you care about.
  3. Recommendation — a sourcing structure and volume split, with the trigger to revisit.

State any assumptions you make.

Hint
Reveal suggested structure

Expected loss = probability x duration x margin per week. Compare against the annual premium of holding a second source. Then test whether the sources are correlated.
