Problem
Scenario
You're advising an engineering leader who needs to make a recurring platform decision under uncertainty. A team has identified a meaningful technical gap, and leadership wants a clear way to decide whether to build the capability internally, buy an external solution, or defer the work until the need is more urgent.
Question
How do you decide whether to build, buy, or defer a technical solution?
What This Tests
- Ability to separate strategic differentiation from commodity capability
- Comfort quantifying trade-offs across cost, speed, and risk
- Judgment on when deferral is rational versus expensive avoidance
- Ability to compare vendor options and internal investment paths
