Your question is Build Versus Buy Decision. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Problem

Scenario

You're advising an engineering leader who needs a structured way to decide whether a new internal capability should be built by the team or purchased from a vendor. The decision matters because the wrong choice can slow roadmap delivery, create long-term maintenance burden, or leave the company dependent on a tool that does not fit its needs.

Question

How do you evaluate whether to build a tool in-house or buy an existing off-the-shelf solution?

What This Tests

  • Ability to structure a build-versus-buy decision
  • Judgment on strategic differentiation versus commodity tooling
  • Use of KPIs and total cost thinking
  • Risk assessment in a regulated environment
