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
