Assignment: A buy-vs-build memo

For a real feature, defended.

Summary

The AI-in-Business Foundations course assignment: a defended buy-vs-build memo.

Key Ideas
  • A buy-vs-build memo forces the honest comparison most teams skip.
  • The revisit rule is what makes the recommendation adaptive.
Assignment

Choose a real AI feature under consideration at your firm (or a firm you know well). Write a two-page memo recommending buy or build. Include: the feature specification, three candidate vendors evaluated against the eight-question framework, a cost model at year-1 and year-3 scales, a build cost estimate (people + infra + timeline), a risk register, and a written recommendation with the decision rule for revisiting.

Deliverables

  • Two-page written memo with recommendation.
  • Vendor comparison table using the eight-question framework.
  • Cost model spreadsheet at year-1 and year-3.
  • Risk register with likelihood, impact, mitigation.

Rubric

  • Rigor — the vendor evaluation is specific, not generic.
  • Cost modeling — both build and buy include hidden costs (people, opportunity, risk).
  • Recommendation — defensible under executive scrutiny.
  • Revisit rule — the memo names what would change the decision.
