Build vs Buy Template

The build-versus-buy decision is deceptively complex. Building gives you control and customization; buying gives you speed and proven reliability. Most teams make this decision based on engineering enthusiasm rather than rigorous analysis.

This template applies the Build vs Buy framework for structured comparison, TCO analysis for lifetime cost modeling, Cost-Benefit Analysis for financial rigor, and Risk Matrix for identifying hidden downsides of each path.

The output is a scored recommendation with full reasoning transparency — so your VP of Engineering and CFO can review the same analysis from different angles.

Best For

  • Engineering teams evaluating custom development vs SaaS procurement
  • CTOs making platform investment decisions
  • Product managers weighing build timelines against vendor capabilities
  • Finance leaders comparing capital vs operating expenditure paths

How to Use This Template

  1. 1

    Define the capability you need and your 2-3 options (build, buy, hybrid).

  2. 2

    Describe constraints: budget, timeline, team capacity, compliance requirements.

  3. 3

    SolveRight models TCO for each path and scores across 4 frameworks.

  4. 4

    Review the risk analysis to identify hidden costs (maintenance, vendor lock-in).

  5. 5

    Export the analysis for cross-functional stakeholder alignment.

Build vs Buy Template — Frequently Asked Questions

What's included in the TCO calculation?+
TCO covers development cost, integration effort, ongoing maintenance, licensing fees, training, migration risk, and opportunity cost. SolveRight estimates these from your description and refines during enrichment.
Can I compare more than two options?+
Yes. Most build-vs-buy decisions benefit from a third 'hybrid' option — buy a platform and customize it. You can add up to 10 options.
How does this handle the 'not invented here' bias?+
The multi-framework approach neutralizes single-perspective bias. If the Build vs Buy framework favors building but TCO and Risk Matrix favor buying, you see the contradiction explicitly — forcing honest evaluation.
