Build-vs-Buy Decision Engine
Settle any build-vs-buy call with a total-cost-of-ownership model, a weighted capability-fit scorecard, a lock-in and exit read, and a decision memo your leadership will actually approve.
A 4-step agentic workflow pack for coding built to run with ChatGPT, Claude, and Gemini. Open the Markdown files, fill the variables, and paste into your model. Most buyers get a reviewable result in about 12 minutes.
- Frame building in-house, buying a vendor, and adopting open source as concrete, comparable options
- Model three-year total cost of ownership for each path, not just the sticker price
- Score every option on a weighted capability-fit, cost, and speed model with explicit anchors
- Expose switching cost, lock-in, and a realistic exit path before you commit budget
- Catalog the failure modes each path is known to hit and set a time-boxed trial with kill criteria
- Ship a decision memo with recommendation, rationale, rejected alternatives, and rollback that stakeholders sign off on
- Replace circular build-or-buy debates with a repeatable, auditable decision you can defend
