PoC to production handoff checklist: 30 items you need to complete before go-live (downloadable template)
PoC impressed leadership, but three months later hadn't cleared QA. The undefined gap nobody owned consumed two quarters of budget. We developed a 30-item handoff checklist covering data, evaluation, security, operations, and adoption. No handoff proceeds until every item is checked. Includes a downloadable template that turns go-live into an itemized verification process.

Last quarter we inherited a project from a manufacturing customer. Their RAG-based Q&A PoC impressed leadership in initial review, delivering fast and accurate responses. Three months later, on-site, the system hadn't cleared QA. What was the gap? Nobody had translated 'works in demo' into 'survives in production.' That undefined middle space without clear ownership consumed two quarters of budget.
We developed a practice: before any PoC goes to production, we create a PoC to production handoff checklist. We're turning 'demo to live' into something you can verify item by item, where someone is responsible. No handoff proceeds until every item is checked.
Why the PoC to production gap is where projects die
PoC success means convincing stakeholders. Production success means sustained operation under real conditions. These are two entirely different engineering problems.
PoCs typically run on clean sample data, operated by people familiar with the system, with no cost if they fail. Production faces dirty data, permission boundaries, traffic spikes, real users unfamiliar with the system, and an audit trail recording all actions. We've seen many teams invest 80% of their effort optimizing model accuracy in the PoC phase, only to find that 80% of production failures stem from data pipelines, security reviews, or lack of user adoption.
The checklist ensures you address these mundane but project-critical items before moving forward.
The 30-item handoff checklist
We organized it into five ownership areas. Each item needs a clear owner and evidence, not just a checkmark.
| Domain | Checklist Item |
|---|---|
| Data | 1. Production data source confirmed, not PoC samples 2. Data pipeline auto-refreshes, not manual imports 3. Rules defined for handling dirty data, nulls, duplicates 4. Data freshness SLA negotiated 5. Sensitive fields masked and de-identified in place 6. Data lineage traceable back to source systems |
| Evaluation | 7. Offline eval set in place, covers real edge cases 8. Accuracy and hallucination baselines quantified, not 'feels right' 9. Regression tests run automatically after each change 10. Post-launch live eval and spot-check review process in place 11. Failed cases have feedback loop back to eval set 12. Acceptance thresholds for performance written into handoff criteria |
| Security | 13. Permissions aligned to source systems, users see only what they should 14. Prompt injection and unauthorized access tested 15. PII and confidential data don't leak to third-party models 16. Audit logs complete, can answer 'who asked what when' 17. Passed security and compliance review, docs retained 18. Key and credential management meets company standards |
| Operations | 19. Monitoring dashboard covers latency, error rate, cost 20. Alert thresholds and on-call owner assigned 21. Cost cap and usage budget set with alerts 22. Degradation and rollback plans rehearsed, not just on paper 23. Dependent models/APIs version-locked with vendor outage contingency 24. Incident runbook written and handed to ops |
| Adoption | 25. Business owner assigned, not just IT 26. Target user population and use cases clearly defined 27. Training and onboarding docs ready 28. Success metric is actual usage rate, not 'deployed' 29. User feedback channel open and monitored 30. 30/60/90-day adoption milestones and checkpoints scheduled |
How to use this checklist without it becoming a checkbox game
We assign each item one of three states: green (has evidence, can be validated), yellow (in progress, timeline set), red (not started). In the handoff meeting, if any item is red, the handoff doesn't proceed. The PoC team keeps carrying it. You don't hand off a black box to operations.
Item 28 is the easiest to skip and the most dangerous. Too many projects treat 'system is live' as the finish line, celebrate, and move on. But our belief is simple: a beautiful demo doesn't count. What counts is the system being live and actually used. The manufacturing customer we started with is a case in point. We didn't rewrite the model. We fixed the data pipeline gaps, completed the security documentation, and provided actual training. Two months later, internal adoption climbed from 0% to 61%. We didn't change a single line of the model.
This is standard in our field deployment engineering (FDE) practice: engineers arrive not just to build a demo, but to work through each of the 30 items with the customer, complete each one, and hand off to whoever will own it long-term. You can download this checklist as a template, but the real challenge is having someone put evidence behind each item.
