How Do We Know Our Build-vs-Buy Call Isn't Fooling Us?
You and your team built a tidy table — cost here, timeline there, flexibility scored out of ten. It feels decided. That feeling is the trap. Clarity is cheap. Anyone can make a decision look clean by choosing what to measure and ignoring the rest. The real test is what your table left out — the maintenance nobody budgeted, the vendor who changes terms next year, the skill your team quietly doesn't have. You don't need more analysis. You need someone in the room asking what the group isn't seeing, before the market or the calendar asks it for you.
Your math can be correct and the decision still wrong, because the cost that hurts you is the one nobody counted. A clear table is not proof of a right choice — it is proof you agreed on what to measure. Before you trust it, name three costs you left out. If your team can't, you aren't finished deciding.
What changes unlock by starting
- Your team names hidden costs before they become expensive surprises.
- You can defend the decision to someone who had no part in making it.
- You know exactly who owns the risk you chose to accept.
- You've built a checkpoint into the plan to catch a wrong call early.
