Operational Readiness Playbook

Guide Origin: Official | ArcKit Version: [VERSION]

/arckit:operationalize creates an operational readiness pack covering support model, runbooks, DR/BCP, on-call, and handover documentation.


Inputs

Artefact Purpose
Requirements (ARC-<id>-REQ-v1.0.md) NFRs for availability, performance, recovery
Architecture diagrams Components for runbook inventory
Risk register Operational risks to mitigate
Data model Backup requirements and data dependencies

Command

/arckit:operationalize Create operational readiness pack for <service>

Output: projects/<id>/ARC-<id>-OPS-v1.0.md


Readiness Pack Structure

Section Contents
Service Overview Name, criticality, tier, stakeholders, dependencies
Service Level Objectives SLIs, SLOs, error budgets, breach response
Support Model Support tiers, escalation matrix, on-call rotation
Monitoring & Observability Health checks, metrics, dashboards, logs, tracing
Alerting Strategy Routing rules, severity definitions, fatigue prevention
Runbooks Service start/stop, health check failures, errors, capacity
Disaster Recovery DR strategy, RTO/RPO, failover/failback procedures
Business Continuity Impact analysis, workarounds, communication plan
Backup & Restore Schedule, retention, verification, restore procedures
Capacity Planning Baseline, projections, scaling thresholds
Security Operations Access management, vulnerability scanning (11.3 with VMS), remediation SLAs (11.4 with VMS benchmarks), patch management (11.5)
Deployment & Release Windows, rollback, feature flags, migrations
Knowledge Transfer Training materials, SME contacts, onboarding
Handover Checklist Comprehensive go-live checklist
Operational Metrics MTTR, MTBF, change failure rate, deployment frequency
UK Government Considerations GDS Point 14, NCSC guidance, cross-government dependencies

Service Tier Mapping

Tier Availability RTO RPO Support On-Call
Critical 99.95%+ <1hr <15min 24/7 Yes, immediate
Important 99.9% <4hr <1hr 24/7 Yes, 15min response
Standard 99.5% <24hr <4hr Business hours Best effort

Runbook Structure

Each runbook must include:

Section Contents
Purpose What problem this runbook addresses
Prerequisites Access, tools, knowledge required
Detection How you know this runbook is needed
Steps Numbered, specific, actionable steps
Verification How to confirm the issue is resolved
Escalation When and how to escalate
Rollback How to undo changes if needed

Standard Runbooks Required

Runbook Purpose
Service Start/Stop Graceful start and stop procedures
Health Check Failures Response when health checks fail
High Error Rate Diagnosis and mitigation for elevated errors
Performance Degradation Response when SLOs are breached
Capacity Issues Scaling procedures (manual and automatic)
Security Incident Initial response for security events
Critical Vulnerability Remediation Response when critical CVEs or VMS alerts require urgent patching
Dependency Failure Response when upstream services fail

One-Page Workflow

Phase Key Activities ArcKit Commands
Discovery Define requirements and architecture /arckit:requirements, /arckit:diagram
Design Create HLD/DLD, identify risks /arckit:hld-review, /arckit:risk
Build Implement, test, document /arckit:backlog, /arckit:devops
Readiness Create operational pack /arckit:operationalize
Go-Live Handover, train, transition /arckit:servicenow

Handover Checklist Summary

  • All runbooks written and reviewed
  • Monitoring dashboards created and tested
  • Alerts configured and tested
  • On-call rotation staffed
  • DR tested within last 6 months
  • Backups verified and restore tested
  • Support team trained
  • Escalation contacts confirmed
  • Access provisioned for support team
  • Documentation in knowledge base
  • SLOs agreed with stakeholders
  • VMS enrolled and scanning active (UK Government)
  • Vulnerability remediation SLAs documented and agreed
  • Critical vulnerability remediation runbook tested

Review Checklist

  • Every NFR has corresponding SLO/SLI.
  • Every major component has a runbook.
  • DR/BCP procedures documented and tested.
  • On-call rotation defined with sustainable schedule.
  • Escalation paths clear with contact details.
  • Training plan exists for operations team.
  • RTO/RPO align with architecture capability.

Key Principles

  1. SRE-First: Define SLIs before SLOs before alerts.
  2. Actionable Runbooks: Specific, numbered steps with actual commands.
  3. Realistic RTO/RPO: Must match architecture capability.
  4. Human-Centric: On-call should be sustainable (no burnout).
  5. Continuous Improvement: Regular reviews, post-incident improvements.
