name: operational-excellence description: Assess a workload's operational excellence posture by analyzing CI/CD pipelines, observability instrumentation, deployment configs, and incident management patterns in the codebase to produce evidence-backed findings. not_for: security assessment, cost optimization, migration planning, reliability assessment, full cross-pillar WA review version: 2.0.0

Operational Excellence Assessment

Step 1: Gather context

Ask the user:

What workload or environment would you like me to assess for operational excellence? Please share:

• Workload name and brief description
• Code packages/directories to analyze (CI/CD configs, IaC, application code)
• Known operational pain points (optional — alert fatigue, slow deployments, etc.)

If the user has already provided details or you are in a codebase, skip the prompt and proceed with discovery.

Step 2: CI/CD and Deployment Discovery

Analyze all CI/CD and deployment configurations in the codebase.

You MUST examine:

• Pipeline definitions (CodePipeline, GitHub Actions, Jenkins, GitLab CI, CDK Pipelines)
• Deployment configurations (CodeDeploy, ECS deployment, Lambda aliases, Apollo)
• Build configurations (buildspec.yml, Makefile, package.json scripts)
• Testing configurations (unit, integration, e2e test setups)
• Pre-deployment gates (approval stages, quality gates, security scans)

For each pipeline/deployment, document:

• File path and line numbers
• Stages and their purpose
• Deployment strategy (canary, blue/green, rolling, all-at-once)
• Rollback mechanism (automatic on alarm, manual, none)
• Test coverage gates
• Artifact promotion flow

You MUST flag:

• All-at-once deployments to production without health check gating
• No rollback mechanism configured
• No automated testing in the pipeline
• Manual steps in an otherwise automated pipeline

Step 3: Observability Discovery

Analyze all monitoring and observability configurations.

You MUST examine:

• CloudWatch alarm definitions (in IaC or config files)
• Dashboard definitions (CloudWatch dashboard JSON, Grafana configs)
• Log configurations (log groups, retention, structured logging libraries)
• Tracing configurations (X-Ray, OpenTelemetry, Jaeger)
• Custom metric publishing (CloudWatch PutMetricData, StatsD, embedded metrics)
• Synthetic canaries (CloudWatch Synthetics)
• Application-level logging (structured logging, correlation IDs, log levels)

For each observability component, document:

• What it monitors and why
• File path and line numbers
• Gaps in coverage (services without alarms, flows without tracing)

You MUST flag:

• Services or Lambda functions with no CloudWatch alarms
• Missing distributed tracing across service boundaries
• Unstructured logging (no JSON, no correlation IDs)
• No custom metrics for business-critical operations
• Log retention set to "never expire" without justification
• No synthetic canaries for critical user journeys

Step 4: Incident and Event Management Discovery

Analyze incident response and event management configurations.

You MUST examine:

• Alert routing (SNS topics, PagerDuty/OpsGenie integrations, EventBridge rules)
• Automated remediation (Lambda functions triggered by alarms, SSM Automation)
• Runbooks and playbooks (SSM documents, markdown runbooks, Step Functions)
• Escalation configurations
• Health check implementations (ALB health checks, Route 53, custom endpoints)

---STOP--- Checkpoint: Discovery complete — ready to evaluate against WA Framework

Discovered CI/CD pipelines ({X} pipeline definitions), observability configurations ({Y} alarm/dashboard/tracing setups), and incident management patterns across {packages analyzed}. Deployment strategies, rollback mechanisms, and monitoring gaps documented.

Shall I proceed with evaluating these findings against the WA Operational Excellence pillar questions and assessing risk levels?

Do NOT proceed past this point until the user explicitly confirms.

Step 5: Evaluate against WA Framework questions

For each question, provide: Status, Evidence (file:line), Gaps, Risk.

OPS 1 — How do you determine what your priorities are?

• Look for: SLO/SLI definitions, business metric dashboards, health check endpoints
• Evidence: alarm thresholds, dashboard panels showing business metrics, README/docs with SLO targets

OPS 2 — How do you structure your organization to support your business outcomes?

• Look for: CODEOWNERS files, clear package boundaries, ownership documentation
• Evidence: CODEOWNERS, package.json team fields, README ownership sections

OPS 3 — How does your organizational culture support your business outcomes?

• Look for: test coverage, PR templates, contributing guides, code review configs
• Evidence: test directories, .github/PULL_REQUEST_TEMPLATE, CONTRIBUTING.md

OPS 4 — How do you implement observability?

• Look for: structured logging with correlation IDs, distributed tracing, custom metrics, dashboards
• Evidence: logger configurations, X-Ray/OTEL SDK usage, PutMetricData calls, dashboard JSON

OPS 5 — How do you reduce defects, ease remediation, and improve flow into production?

• Look for: automated testing (unit, integration, e2e), linting, security scanning, staged deployments
• Evidence: test files, ESLint/prettier configs, SAST tool configs, pipeline stage definitions

OPS 6 — How do you mitigate deployment risks?

• Look for: canary/blue-green deployments, feature flags, automated rollback, deployment alarms
• Evidence: CodeDeploy deployment configs, feature flag SDK imports, rollback alarm ARNs

OPS 7 — How do you know that you are ready to support a workload?

• Look for: runbooks for known failure modes, pre-deployment checklists, load testing, operational readiness reviews
• Evidence: SSM documents, runbook markdown files, load test scripts, readiness configs

OPS 8 — How do you understand the health of your workload?

• Look for: composite alarms, health dashboards, dependency health tracking, SLI monitoring
• Evidence: CompositeAlarm constructs, dashboard definitions, health check endpoints

OPS 9 — How do you understand the health of your operations?

• Look for: DORA metrics tracking, deployment success monitoring, pipeline health dashboards
• Evidence: pipeline metrics, deployment monitoring alarms, operational dashboards

OPS 10 — How do you manage workload and operations events?

• Look for: EventBridge rules for operational events, automated remediation Lambdas, escalation configs
• Evidence: EventBridge rule definitions, remediation Lambda code, SNS topic subscriptions

Step 6: Risk Assessment

For each finding, assess using Impact × Likelihood:

Impact: Minor (inconvenience, manual workaround exists) | Moderate (delayed detection, extended recovery time) | Severe (undetected outage, no rollback, data loss)

Likelihood: Low (requires unusual conditions) | Medium (possible under normal operations) | High (likely to occur during next incident or deployment)

Step 8: Offer follow-up

After delivering the assessment, offer:

Would you like me to:

• Deep-dive into CI/CD, observability, or incident response?
• Generate CloudWatch alarm and dashboard IaC for gaps identified?
• Create runbooks for specific failure modes?
• Design a self-healing architecture for a recurring issue?
• Implement structured logging with correlation IDs?

Calibration Guidance

• A workload with CI/CD pipelines, automated rollback, CloudWatch alarms, and structured logging is MATURE — focus on advanced improvements (chaos, SLO-based alerting, operational reviews)
• Every finding MUST have code evidence — no generic "you should have monitoring" without checking what exists
• If something cannot be determined from code (e.g., on-call rotation quality, incident review process), mark "Cannot Determine" and explain what information is needed
• Acknowledge existing operational strengths explicitly before listing gaps
• For workloads transitioning architectures, focus on what the NEW architecture introduces as operational requirements
