Practice a structured build-versus-buy product decision framework. The solution compares build, buy, and hybrid options across strategic differentiation, total cost of ownership, time to market, reliability, maintenance, vendor lock-in, data portability, pilots, stakeholder review, and risk mitigation.
##### Question
Your team needs a new system. Describe how you would decide whether to build it in-house or buy an off-the-shelf solution. Discuss evaluation criteria such as cost, time-to-market, scalability, maintenance, vendor lock-in, and strategic differentiation.
Quick Answer: Practice a structured build-versus-buy product decision framework. The solution compares build, buy, and hybrid options across strategic differentiation, total cost of ownership, time to market, reliability, maintenance, vendor lock-in, data portability, pilots, stakeholder review, and risk mitigation.
Prototype or POC with real workflows and performance tests.
Weighted scorecard plus narrative recommendation.
Risk mitigation, contract terms, data portability, and exit strategy.
Decision review with stakeholders.
What a Strong Answer Covers Guidance
A strong answer separates commodity from strategic capabilities, quantifies total cost and opportunity cost, validates vendor and internal feasibility, and makes a recommendation with explicit trade-offs and risk mitigations.
Follow-up Questions Guidance
When would you buy now and build later?
How would you avoid vendor lock-in?
What if the vendor is faster but fails a security requirement?
What internal cost do teams usually underestimate?
How would your recommendation change if this capability became strategically differentiating?
