Build vs buy: when should you build software yourself?
A decision framework for balancing control, speed, maintenance and opportunity cost when selecting software.
Is the capability strategically differentiated enough to justify ownership?
There is no universal best tool. The right decision depends on the workflow, stage, team, technical capacity and cost behavior you can support.
What to evaluate
- Buy commodity capabilities when speed and reliability matter more than differentiation.
- Build when the capability itself is a durable competitive advantage or a critical constraint.
- Include maintenance, security and future migration in the cost of building.
What to avoid
- Equating technical control with business advantage.
- Ignoring maintenance capacity.
- Building before validating the requirement.
