Scenario

Lumen Learning is a growth-stage edtech business in India. It currently buys a key component from a third-party supplier and is considering manufacturing it in-house.

Current position:

  • Annual volume: 276k units
  • Supplier price: ₹235 per unit, delivered

The in-house proposal:

  • Capital cost: ₹72 Cr, useful life 10 years
  • Variable cost in-house: ₹146 per unit
  • Additional fixed operating cost: ₹13 Cr per year

Complications:

  • Demand for the end product could move ±27% over the next three years
  • The supplier has offered a price reduction if a three-year commitment is signed
  • In-house production would take about 14 months to reach full yield

The COO is convinced building is obviously cheaper because the unit cost is lower.

Your task

Advise the COO. Your answer should provide:

  1. Analysis — the economics of both options, computed, including the volume at which they break even.
  2. Risks — what makes the in-house case fail, and what you would monitor.
  3. Recommendation — a specific decision, and the volume threshold that would reverse it.

State any assumptions you make.
