Direct answer: A factory AI POC is not a model demo. It is a decision gate covering whether the problem is worth solving, whether the data can support it, whether the system can be integrated, whether people can take over when it fails, and whether anyone will maintain it after launch. Without a baseline, a test set, a fallback and an owner, a smooth demo should not go into production.
This guide is for manufacturers in Changzhou and nearby cities, including Taizhou, Wuxi, Zhenjiang and Danyang, plus their IT, operations, quality and procurement teams. Information is current to 2026-10-26. Metrics, timelines and costs depend on the scenario, data and contract; this article does not promise a fixed accuracy, saving, delivery timeline or project outcome.
A POC is a decision gate, not a demo; without a baseline and test set there is no acceptance; AI must not bypass ERP/MES, permissions or human fallback.
What does a factory AI POC actually prove?
A factory AI POC proves a repeatable business result: whether the same real samples meet agreed metrics, whether people can take over when it fails, and whether someone maintains it after launch.
“The quality-inspection demo looks accurate” or “the model can answer questions” does not mean the system is ready for production. A POC must answer five questions: is the problem worth solving; is the data usable and authorized; can AI fit the existing process; are human review and exception handling acceptable; and who owns operations after launch. The scenarios differ across Changzhou, Taizhou, Wuxi, Zhenjiang and Danyang, but the acceptance logic is the same.
| Stage | Main deliverables | Acceptance points | Common failure signal |
|---|---|---|---|
| Problem and baseline | One-page scenario, current process, baseline, business owner | Problem is measurable; current state and failure impact are clear; operations, IT and business agree | Only “improve efficiency”, no baseline |
| Data and permissions | Sample list, labeling rules, authorization, train/test split | Data represents real distribution; source and use are authorized; missing and abnormal samples are documented | Dirty data, no rights, or demo samples only |
| Integration | Interface/deployment diagram, permission matrix, logs, rollback plan | Boundaries are clear; failure returns to manual work; AI does not bypass ERP/MES to change production data | Treating AI as an ERP/MES replacement |
| POC test | Blind test set, comparison, failure samples, human review log | Effect, review cost and failure cost are measured together; results are repeatable | Only a demo, no false-negative review |
| Launch | Acceptance report, SOP, training records, monitoring metrics | Stop and rollback are executable; owners and escalation are clear | No operations owner; nobody reads metrics |
| Operations | Logs, drift monitoring, retraining/change log, cost ledger | Thresholds trigger action; model, data and permission changes are traceable | No maintenance after launch; costs drift |
These acceptance points are a project-design reference, not an industry standard. Thresholds, sample size and duration depend on the scenario, data and contract.
Stage 1: Define the problem and baseline
Write the business problem, current process, baseline and result owner on one page; if the current state and failure impact cannot be explained, the project is not ready for a POC.
A baseline is not “we can do it today”. It is the actual performance of the current manual or system process: cycle time, cost, accuracy, rework, downtime and customer complaints. Without it, you cannot tell whether AI improved the process or merely moved the cost. Common manufacturer problems include missed defects, Excel-based scheduling, late equipment warnings, and disconnected reporting and approvals; each must be tied to a specific operation, role or document.
- Problem: Name the operation, role or document, such as “a type of cosmetic defect is missed and causes rework”, not “improve intelligence”.
- Baseline: Pick at least one measurable metric: cycle time, review rate, missed/false detections, rework cost, downtime or complaints.
- Owners: Name the business, data, IT/integration and final acceptance owners; the vendor alone is not enough.
- Boundary: State what the POC will and will not test, including lines, shifts, samples and systems.
- Failure impact: Explain who is affected by a false result, downtime, data leak or failed takeover, and how to stop the damage.
Stage 2: Validate data and permissions
Data acceptance covers source, authorization, quality, labeling and train/test isolation; without usable samples and a data owner, fix the data before choosing a model.
Manufacturing data sits in ERP, MES, QMS, PLCs, paper records and spreadsheets. A POC does not need all data, but it needs samples that represent the real distribution and a reproducible labeling or decision rule. For images, audio, process parameters or customer data, also confirm purpose, retention, de-identification and access rights.
| Check | Question to ask | Acceptable evidence |
|---|---|---|
| Source | Which line, shift, system or work order produced the samples? | Sample list, sampling rule, time range and exclusions |
| Authorization | May customer, employee, supplier and process data be used for training or testing? | Data-use authorization, de-identification record, access approval |
| Quality | How are missing, duplicate, mislabeled and abnormal samples handled? | Labeling rule, review record, data-quality report |
| Isolation | Is the test set independent, or was it seen during training? | Train/validation/test split and blind-test procedure |
| Ownership | Who maintains data, approves changes and handles deletion? | Data owner, permission matrix, retention and deletion rules |
If data is insufficient, run a small feasibility test or fix the data first. Do not use unauthorized data, personal information or unknown samples just to get a model running.
Stage 3: Integrate with fallback and control
Integration acceptance maps ERP/MES/OA, equipment and network boundaries, then defines fallback, logs, permissions and downtime; AI must not bypass existing systems to change production data.
A POC may run in a sandbox or on read-only data, but production touches work orders, quality records, equipment parameters or approvals. Decide in advance whether AI output is a recommendation or an automatic action, who can change thresholds, whether a timeout or model failure returns the process to manual work, and whether logs can trace the sample, model version and operator.
- Interfaces: Separate read and write access across ERP/MES/OA, QMS and PLC/SCADA; use least privilege and no shared administrator accounts.
- Human fallback: Define the exception queue, owner, response time and escalation; rehearse it during the POC.
- Logs: Record input, output, model/rule version, confidence, manual override and final result for review.
- Downtime: State deployment, cutover and rollback duration, and whether a line or only one station is affected.
- Boundary: Do not treat AI as a replacement for ERP/MES; integration and master-data quality remain the foundation.
Stage 4: Set metrics and stop conditions
POC metrics depend on the scenario; measure effect, human-review cost and failure cost together. If metrics, data or ownership fail, stop or narrow the scope.
Do not write only “accuracy ≥ 95%”. Quality inspection needs missed detections, false positives, recall by defect type and human review rate; scheduling needs delivery, work-in-progress, changeover time and exception handling; maintenance needs warning lead time, false alerts and downtime loss. Every metric needs a test set, calculation rule and baseline; otherwise it is a slogan.
| Dimension | Example metrics | Question at acceptance |
|---|---|---|
| Effect | Recall, missed detections, false positives, accuracy, human review rate | Is there an independent blind test set? Are defects and operating conditions separated? |
| Efficiency | Cycle time, processing time, queue time, manual takeovers | Are human review and exception handling included? |
| Cost | Inference, review, integration, operations and change cost | Did the estimate include labor and integration, not just model fees? |
| Risk | Excess permission, data leak, wrong action, downtime, rollback time | Who can stop it, how fast is recovery, and who is accountable? |
| Maintainability | Model/rule changes, retraining, monitoring and alerts | Who owns it after launch, and how often is it reviewed? |
Example metrics are for design discussion, not a performance promise. Thresholds, sample size and evaluation method should be agreed in writing before the POC.
Stop conditions to put in the POC:
- Critical data is unavailable, unauthorized or too poor to support the test.
- The baseline is unclear, or the gain comes only from reducing human review.
- Integration must bypass ERP/MES or permissions, or failure cannot return to manual work.
- Review cost, false-result loss or downtime risk exceeds the acceptable range.
- No business owner and no operations owner are named for post-launch support.
- The vendor refuses to provide a test set, failure samples or verifiable acceptance records.
Stage 5: Plan launch, operations and retraining
Before launch, require an acceptance report, rollback plan, owner and monitoring; after launch, review drift, escalation, retraining and change approval instead of abandoning the system.
Passing a POC does not justify a plant-wide rollout. Start with one line, station or shift, keep human review and the old process as fallback, and monitor input distribution, model version, false results, manual takeovers and business metrics. Changes in data distribution, equipment, process or customer standards can invalidate the model; every model, rule, permission or interface change needs approval and a rollback record.
Contract and vendor checks
Write scope, data ownership, acceptance metrics, test set, fallback, operations and cost boundaries into the contract; a vendor list is a lead, not a substitute for a POC, due diligence and contract terms.
The Changzhou municipal AI service-provider capability list is a public reference formed through an official call for providers. It is not a designated procurement list, a ranking or a guarantee of project success. Use it to find leads, then verify the team, comparable scenarios, data security, delivery record and contract terms. The clauses below matter more to acceptance than the size of a model.
| Clause | What to write | Why it matters |
|---|---|---|
| Scope | Scenario, line/station, sample scope, system boundary, explicit exclusions | Prevents scope creep and shifting acceptance rules |
| Acceptance | Test set, metrics, calculation rules, baseline, reviewers, pass/stop conditions | Turns “looks good” into a verifiable result |
| Data | Ownership, use authorization, de-identification, retention, deletion and export | Prevents unclear rights to customer or process data |
| Fallback | Manual takeover, rollback time, downtime window, escalation | Protects production when a model or interface fails |
| Operations | Monitoring, retraining, change control, response time, fees and exit | Prevents an unmaintained system or uncontrolled cost |
| Cost | Price software, compute, integration, implementation, training, operations and change separately | Avoids comparing model unit prices while missing total cost |

FAQ
Must a factory AI POC use real production data?
Prefer authorized production samples that represent the real distribution. De-identified or sandbox data can support early feasibility work, but explain how it differs from production. Do not use unauthorized customer data, personal information or unknown samples just to start modeling.
How long does a POC take?
There is no universal duration. Data preparation, labeling, interfaces, human review and acceptance scope all affect it. If a vendor gives only a short number without sample size, dependencies and stop conditions, ask for the assumptions. This article does not promise a fixed timeline.
Is 95% accuracy enough to go live?
No single accuracy number is enough. Also examine the business cost of missed and false results, performance by defect or operating condition, human review rate, baseline comparison, fallback and operations cost. A 95% result on a demo set does not mean stable 95% in production.
What if we have no labeled data?
Confirm the business problem and decision rule, then run a small labeling trial with a written rule, review and version control. Without a data owner and a reproducible labeling process, fix the data first rather than buying a model or platform.
Does the official provider list make a vendor more reliable?
The list is a capability reference, not a designated procurement list, ranking or performance guarantee. Verify comparable scenarios, team stability, data security, delivery records and contract terms, and use a real test set in the POC.
Can you serve factories in Taizhou, Wuxi, Zhenjiang and Danyang?
We can confirm the service model on a project basis, but Lingyi does not claim branches or local teams in those cities, or a fixed on-site frequency. Fit depends on the scenario, data, system boundary and project scope.
Bottom line
A factory AI POC should first use a baseline and real samples to prove the problem is worth solving, then use integration, fallback and operations to prove it can go live safely. A POC without stop conditions often becomes a demo without a decision.
