ES-112 — Deployment and Transition

Move the approved operational scope into its target environment while preserving release limits, transition controls, rollback ability, user communication, and deployment evidence.

ES-112 Readiness Gate

Purpose

This readiness gate verifies that ES-112 is complete and ES-113 can begin responsibly.

Operations and monitoring should not begin until deployment and transition evidence confirms the system was exposed within approved boundaries.

Completion standard

You are ready to continue when each gate is satisfied or explicitly marked not applicable with rationale.

Gate 1 Deployment overview

Review Question

Does the deployment overview connect to ES-111 operational readiness?

Required Evidence

docs/deployment/deployment_overview.md

Status: ☐ Yes ☐ Needs review

Gate 2 Deployment scope

Review Question

Does deployment scope match release and operational scope?

Required Evidence

docs/deployment/deployment_scope.md

Status: ☐ Yes ☐ Needs review

Gate 3 Deployment plan

Review Question

Is deployment sequence, ownership, and stop points defined?

Required Evidence

docs/deployment/deployment_plan.md

Status: ☐ Yes ☐ Needs review

Gate 4 Environment readiness

Review Question

Was target environment readiness checked before deployment?

Required Evidence

docs/deployment/environment_readiness_check.md

Status: ☐ Yes ☐ Needs review

Gate 5 Deployment execution

Review Question

Was deployment execution recorded?

Required Evidence

docs/deployment/deployment_execution_record.md

Status: ☐ Yes ☐ Needs review

Gate 6 Transition communication

Review Question

Was transition communication prepared and delivered?

Required Evidence

docs/deployment/transition_communication.md

Status: ☐ Yes ☐ Needs review

Gate 7 Access and data transition

Review Question

Were access and data controls confirmed?

Required Evidence

docs/deployment/access_and_data_transition_record.md

Status: ☐ Yes ☐ Needs review

Gate 8 Rollback validation

Review Question

Was rollback, pause, disablement, or stop approach validated?

Required Evidence

docs/deployment/rollback_validation_record.md

Status: ☐ Yes ☐ Needs review

Gate 9 Post-deployment check

Review Question

Were post-deployment checks completed?

Required Evidence

docs/deployment/post_deployment_check.md

Status: ☐ Yes ☐ Needs review

Gate 10 Transition readiness

Review Question

Does the readiness summary explain why ES-113 can begin?

Required Evidence

docs/deployment/deployment_readiness_summary.md

Status: ☐ Yes ☐ Needs review

Exit criteria

ES-112 is complete when deployment and transition evidence is sufficient for operations and monitoring to begin.

If not ready

If ES-112 is not ready, do not enter operations and hope monitoring will catch up.

Return to the activity or prior stage that owns the gap: operational readiness, release readiness, environment readiness, access, data, rollback, transition communication, or post-deployment verification.

Common Pitfall

Do not enter ES-113 if the deployed scope is unclear.

Engineering Insight

The readiness gate ensures operations inherits a known deployed state, not a mystery.
