Build vs Buy

Systematically compare building custom solutions vs using off-the-shelf products or services.

Context

You are deciding between building custom or buying existing. Establish clear decision criteria and cost models.

Domain Context

Based on make-vs-buy decision frameworks:

• Build: Full control, learning investment, ongoing maintenance cost
• Buy: Faster time-to-market, but less control, vendor lock-in risk
• Hybrid: Use product but customize parts
