How do you scope a proof of concept so that it closes the deal?

7 min readUpdated 2026-08-15

Answer

Short answer

Scope a POC around the two or three technical claims genuinely in doubt, with written pass/fail exit criteria signed off by the person who will decide, a hard time box, and named customer resources committed before any work starts.

Likely follow-ups

  • The customer wants to run the POC themselves with your product and no help. How do you respond?
  • Two weeks in, the sponsor asks to add a criterion that was explicitly out of scope. What do you do?
  • How does your scoping change when three vendors are running POCs on the same criteria in parallel?
  • The POC passes every criterion and the deal still does not close. What went wrong upstream?
