# Phase 8: Enterprise Pilot with Monitoring and Operations

> Phase 8 delivers the Enterprise Model v1 pilot with update protocols, rollback procedures, runbooks, monitoring, alerting, and disaster recovery drills for production readiness.

Phase 8 is the enterprise pilot phase where EMEP transitions from a technical platform to a production-grade service operated by customer teams. In this phase, you release Enterprise Model v1, establish operational procedures including update protocols and rollback, create runbooks for on-call engineers, and implement monitoring and alerting for model health and infrastructure. The phase culminates in a disaster recovery drill that validates the operational readiness of the entire system.

## Purpose

The purpose of Phase 8 is to prove that EMEP can be safely operated in a customer production environment. This phase moves beyond engineering correctness to operational reliability, ensuring that updates are predictable, failures are detectable, and recovery is rehearsed before full production load is accepted.

## Entry Criteria

Phase 8 begins when the following entry criteria are satisfied:

* Phase 7 (Offline Deployment) is complete and produces signed, secure deployment packages
* The [DeploymentManager](/deployment/deployment-specification) can stage releases to a pilot environment
* Monitoring infrastructure (metrics, logging, tracing) is provisioned in the pilot environment
* On-call rotation and escalation policies are defined
* A disaster recovery plan is drafted and approved by customer stakeholders

## Exit Criteria

Phase 8 is complete when all exit criteria are met:

* Enterprise Model v1 is deployed to the pilot environment and serving live traffic or batch workloads
* Update protocol documents the release cadence, approval gates, and staging progression
* Rollback procedure is tested and can revert to the previous release in under 10 minutes
* [Operations runbook](/operations/runbook) covers common incidents, diagnostics, and remediation steps
* Monitoring dashboards display model health, inference latency, error rates, and resource utilization
* Alerting rules fire on critical conditions with defined severity levels and escalation paths
* Disaster recovery drill is executed successfully with documented results and action items

## Primary Components

| ------------------------------------------------------------ | -------------------------------------- | ------------------------------------------------------- |
| [DeploymentManager](/deployment/deployment-specification)    | `/deployment/deployment-specification` | Stages and promotes releases through pilot environments |
| [InferenceBackend](/deployment/inference)                    | `/deployment/inference`                | Serves model inference in the pilot environment         |
| [ExperimentTracker](/tracking/experiment-tracking)           | `/tracking/experiment-tracking`        | Correlates production metrics with model versions       |
| [Operations Runbook](/operations/runbook)                    | `/operations/runbook`                  | Guides on-call engineers through incident response      |
| [Secure Model Packaging](/enterprise/secure-model-packaging) | `/enterprise/secure-model-packaging`   | Ensures enterprise packaging standards are maintained   |

## Deliverables

The following deliverables are produced in Phase 8:

1. **Enterprise Model v1**: The first merged, evolved, quantized, and packaged model approved for pilot deployment
2. **Update protocol**: Documented procedure for releasing new model versions, including staging, canary, and full promotion
3. **Rollback procedure**: Tested, timed process for reverting to the previous known-good release
4. **Operations runbook**: Living document with incident categories, diagnostic commands, and remediation playbooks
5. **Monitoring stack**: Dashboards and metrics pipelines for model performance, infrastructure health, and business KPIs
6. **Alerting rules**: Configured alerts with severity levels, routing, and escalation to on-call engineers
7. **Disaster recovery drill**: Executed rehearsal of failure scenarios with documented recovery times and lessons learned

## Dependencies

Phase 8 depends on the completion of earlier phases and specific operational readiness:

* **Phase 7**: Requires secure, signed deployment packages as the release artifact
* **Phase 4**: Requires benchmark baselines to detect production performance drift
* **Operations team**: Must be trained on the [runbook](/operations/runbook) and tooling before pilot launch
* **Customer stakeholders**: Must approve the pilot scope, success criteria, and go/no-go decision timeline

## Key Tasks

The detailed task breakdown for Phase 8 is maintained in the project task tracker. See [Phase 8 Tasks](/project/tasks) for assigned owners, estimates, and current status.

## Risks

The primary risks in Phase 8 include undetected model drift in production, alert fatigue from noisy monitoring, and rollback failure during a live incident. These risks and their mitigations are documented in the [Risk Register](/risk/risk-register).

## Quality Gate

Before Phase 8 can be marked complete, the following quality gate must pass:

* Enterprise Model v1 serves pilot traffic for at least 72 hours without unplanned downtime
* A simulated incident is detected by monitoring and resolved using the [runbook](/operations/runbook) within SLA targets
* Rollback from a staged bad release completes in under 10 minutes with zero data loss
* Disaster recovery drill achieves recovery time objective (RTO) and recovery point objective (RPO) targets
* Post-drill retrospective identifies no critical gaps in operational readiness

## Position in Roadmap

Phase 8 is the capstone operational phase that validates EMEP as a production-ready system. It consumes all prior technical phases and establishes the operational foundation for sustained customer value.
