+# Operational Acceptance Documentation
+
+## Overview
+
+Prepare complete acceptance packages for production deployment. Core principle: **Document readiness, risks, and acceptance criteria for informed go-live decisions**.
+
+**Key insight**: Acceptance documentation enables stakeholders to make informed risk decisions about production deployment.
+
+## When to Use
+
+Load this skill when:
+- Preparing systems for production launch
+- Seeking executive go-live approval
+- Completing operational handover
+- Government/defense system authorization
+
+**Symptoms you need this**:
+- "How do I get approval to launch?"
+- Preparing production readiness checklist
+- Creating go-live approval package
+- Operational handover to support team
+
+**Don't use for**:
+- Development/staging deployments
+- Internal-only tools (unless high-risk)
+

+
+## Real-World Impact
+
+**Systems using operational acceptance documentation**:
+- **Customer Portal Launch**: Go-live approval package enabled same-day executive approval (vs 1-week review cycle). Clear risk acceptance + rollback plan gave confidence to approve.
+- **Government System**: Complete readiness checklist (infrastructure, operations, testing, security authorization) passed IRAP assessment on first attempt. Assessor: "Most comprehensive readiness documentation in 5 years".
+- **Operational Handover**: Training + runbooks + incident drill enabled junior SRE to respond to P1 database outage successfully within 45 minutes (first week post-handover).
+
+**Key lesson**: **Comprehensive acceptance documentation (readiness, risks, criteria, handover) enables informed go-live decisions and smooth operational transitions.**
