TL;DR: Most authorization proof-of-concepts fail quietly because teams scope them poorly, measure the wrong things, or never define success before starting, according to Cerbos and Sapphire Ventures’ survey of Global 2,000 IT executives. A good POC is short, tied to one real service, and judged on business rules, latency, auditability, and migration fit rather than demo polish.
Editorial analysis by NHI Mgmt Group, based on content published by Cerbos: “The authorization POC guide: What to test, who to involve, and how to decide”.
By the numbers:
- 78% of Global 2,000 IT executives said fewer than half of their POCs result in production deployments.
Key questions
Q: How should teams scope an authorization proof of concept?
A: Scope the POC to one real service with real users, real roles, and real authorization complexity.
Q: What should teams measure to judge an authorization POC?
A: Measure whether the system expresses actual business rules, keeps latency acceptable under realistic load, produces audit logs detailed enough for reconstruction, and is understandable enough for a new developer to use.
Q: What breaks when an authorization POC has no defined success criteria?
A: The evaluation becomes subjective.
Practitioner guidance
- Define pass or fail criteria before the first test Write measurable success criteria for business-rule coverage, latency, audit quality, policy maintainability, and migration fit before the POC begins.
- Limit the POC to one real service Choose a service with live users, representative roles, and real authorization complexity so the evaluation reflects production conditions instead of a sandbox.
- Measure baseline performance and process friction Capture current permission-change time, developer ramp-up, and audit preparation effort so the POC can prove actual improvement rather than perceived value.
Bottom line: Authorization POCs fail most often because teams scope them as demos instead of decision exercises.

Authorization POCs are governance exercises before they are technology tests. The primary failure is not that policy engines cannot work, but that teams use a demo format for a production decision. That shifts the burden away from measurable controls and toward subjective interpretation, which is a weak basis for any identity architecture decision. Practitioners should treat the POC as a control validation exercise with explicit exit criteria.
A question worth separating out:
Q: Who should review an authorization POC before approval?
A: Security, compliance, product, and engineering should all review it. Engineering validates the integration, security validates the decision logs and control strength, compliance checks evidence quality, and product confirms that the policy behavior matches the intended business rules.
