The enterprise proof of concept is, in principle, a structured test of whether the product delivers the promised value in the customer's specific environment. In practice, it's often a loosely structured 60-day period during which the prospect plays with the product, the vendor provides support, and everybody hopes for the best.
The POCs that convert to purchase share design characteristics that the unsuccessful ones lack.
POC design that converts:
Pre-defined success criteria that are agreed upon by the economic buyer. Not "we'll see how it goes." Specifically: "The POC will succeed if we demonstrate X outcome by Y date, as measured by Z method." The economic buyer's agreement on success criteria means the POC result is pre-committed to inform their decision.
A limited, focused scope. The best POCs test one specific, high-stakes use case — not the product's full capability. The focused POC produces a clear answer faster and with less implementation overhead than the comprehensive POC that never reaches decisive conclusions.
Dedicated customer resources for the POC period. A POC conducted by a team that's allocating 10% of their attention to it will produce a mediocre result regardless of product quality. At the start of the POC, confirm that the customer has identified an internal POC lead with dedicated time.
Staged milestone reviews. Not a single evaluation at the end of 60 days, but check-ins at day 15 and day 30 that allow course correction. If the POC is off-track at day 15, 45 more days won't fix it — but a scope adjustment might.
A defined decision timeline. The POC ends on a specific date with a scheduled decision meeting. No extensions without an explicit reason and new success criteria.
The POC that's designed to produce a clear business outcome produces a clear purchase decision. The POC that's designed to let customers evaluate produces a long deliberation.
