# System overview

A high-level view of IntelFactor components and responsibilities.

IntelFactor separates responsibilities into on-site execution and optional aggregation layers.

The inspection loop is designed to be local-first. Visibility layers are optional.

### On-site responsibilities

* Observes live production processes.
* Produces consistent inspection outcomes.
* Captures evidence for traceability.
* Maintains continuity during connectivity loss.

### Site and cloud responsibilities (optional)

* Aggregates visibility across lines, sites, and time.
* Enables broader analysis and reporting.
* Supports centralized review workflows where applicable.

### Integrations (as applicable)

IntelFactor complements MES/ERP and quality systems. It does not replace them.

### Where to go deeper

* Zone boundaries: [Edge-native architecture (three-zone model)](/docs/home/architecture/edge-native-architecture-three-zone-model.md)
* Evidence guarantees: [Evidence & retention policy](/docs/home/edge-pipeline/evidence-and-retention-policy.md)
* RCA loop: [Local RCA engine (4 layers)](/docs/home/closed-loop-rca/local-rca-engine-4-layers.md)
