System Audit

Conduct comprehensive evaluation of system architecture and identify improvement opportunities.

Context

You are auditing a system's architecture. Assess design quality, technical debt, operational readiness, scalability potential. Read code, infrastructure, metrics, team feedback.

Domain Context

Based on architecture assessment frameworks:

• Design Quality: Modularity, coupling, cohesion. Is architecture aligned with business domains? Easy to change?
• Operational Readiness: Monitoring, alerting, logging, runbooks. Can ops team run this effectively? What happens when it fails?
• Scalability: Can it handle 10x growth? What's the bottleneck? Vertical or horizontal scaling?
• Technical Debt: What's slowing teams down? What would refactoring improve?
• Security and Compliance: Data protection, access control, audit trails, regulatory alignment?

Instructions

1. Prepare Audit Checklist:

   • Architecture & Design (modularity, coupling, domain alignment)
   • Data (model, storage, flow, governance)
   • Scalability (bottlenecks, growth headroom)
   • Operations (monitoring, logging, alerting, runbooks)
   • Security & Compliance (data protection, access control, audit)
   • Team Productivity (deployment time, testing capability, cycle time)

2. Gather Information:

   • Read architecture documentation, design documents
   • Review code structure, dependencies
   • Check infrastructure-as-code, deployment pipelines
   • Interview team: "What's hard? What's slow? What worries you?"
   • Review metrics: latency, error rate, utilization, deployment frequency

3. Assess Each Area:

   • Score: Good (no action needed), Fair (monitor, improve over time), Poor (urgent)
   • Document evidence: "Monolith 500K lines, 30-min builds, hard to test"

4. Identify Patterns:

   • Common themes? Multiple "poor" scores suggest systemic issues.
   • Root causes: "Tight coupling causing hard deployments and scaling issues"

5. Recommend Improvements:

   • Prioritize by impact and effort
   • Quick wins (low effort, high impact): improve monitoring, document runbooks
   • Strategic initiatives (high effort, high impact): decompose monolith, refactor critical paths
   • Timeline: what's urgent vs 2-year plan?

6. Document and Present:

   • Written report with findings and recommendations
   • Present to leadership and team
   • Create roadmap for improvements
   • Follow up in 6 months to measure progress

Anti-Patterns

• Audit Without Action: Produce report, file it away. Result: wasted effort, team cynicism. Guard: Use audit to drive improvements; track follow-up.
• Oversimplified Scoring: Everything is "good" or "poor" with no nuance. Result: not actionable. Guard: Explain context; acknowledge tradeoffs; show path forward.
• Ignoring Team Input: Audit from outside perspective only. Result: miss what team actually struggles with. Guard: Interview team; their perspective is crucial.
• Unrealistic Recommendations: Suggest complete rewrite. Result: ignored, too ambitious. Guard: Suggest achievable improvements; prioritize by ROI.
