AI Monitoring
Model drift detection, data quality monitoring, LLM output evaluation, hallucination detection, and LLMOps.
AI Monitoring is a core discipline within Ai Practice. It defines how technology systems should be designed, implemented, and governed to achieve reliable, secure, and maintainable outcomes that serve both technical teams and business stakeholders.
Applying AI Monitoring standards reduces system failures, accelerates delivery, and provides the governance evidence required by enterprise clients, regulators like BSP, and certification bodies like ISO. Top technology companies (Google, Microsoft, Amazon) treat these standards as competitive differentiators, not compliance overhead.
📖 Detailed Explanation
Model drift detection, data quality monitoring, LLM output evaluation, hallucination detection, and LLMOps.
Industry Context: Applied in enterprise architecture practice at leading technology organizations.
Relevance to Philippine Financial Services: Organizations operating under BSP supervision must demonstrate mature ai practice practices during technology examinations. The BSP Technology Supervision Group evaluates documentation quality, process maturity, and evidence of systematic practice — all of which are addressed by the standards in this section.
Alignment to Global Standards: The practices documented here are aligned to frameworks used by Google, Amazon, Microsoft, and the world's leading consulting firms (McKinsey Digital, Deloitte Technology, Accenture Technology). They represent the current industry consensus on best practices rather than any single vendor's approach.
Engineering Perspective: For engineers, AI Monitoring provides concrete patterns and anti-patterns that prevent common mistakes and accelerate development by providing proven solutions to recurring problems. Rather than rediscovering what doesn't work, teams can apply battle-tested approaches with known trade-offs.
Architecture Perspective: For architects, AI Monitoring provides the design vocabulary, decision frameworks, and governance artifacts needed to make and communicate complex technical decisions clearly and consistently.
Business Perspective: For business stakeholders, AI Monitoring provides assurance that technology investments are aligned to industry standards, reducing the risk of expensive rework, regulatory findings, and system failures that impact customers and revenue.

🌎 Real-World Examples
Klarna deployed an AI assistant handling 2.3M conversations in its first month — equivalent to 700 full-time agents. Human-in-the-Loop gates activate for refund decisions above €500. Graceful degradation routes low-confidence queries to human specialists. EU AI Act compliance required all HITL controls before launch. Every AI response displays a confidence indicator and escalation option.
✓ Result: 35% reduction in average resolution time; customer satisfaction maintained at 4.1/5 despite 10× volume increase
JPMorgan's Contract Intelligence (COIN) reviews 12,000 commercial credit agreements in seconds — work that previously took 360,000 lawyer-hours annually. HITL is mandatory: the model cannot make final credit decisions. Every finding cites the exact contract clause supporting it (explainability NFR). OCC and Federal Reserve examine COIN's model governance framework annually.
✓ Result: 360,000 lawyer-hours reduced to seconds; error rate dropped from 1.2% (human) to 0.03% (AI+HITL)
Siemens' AI-Rad Companion analyzes CT and MRI scans. EU MDR mandates HITL as a legal requirement — AI findings are decision support, not decisions. SHAP-based explainability shows which image regions drove findings — required for CE marking. Graceful degradation: GPU unavailability routes scans to priority human review queue automatically.
✓ Result: Radiologist review time per scan reduced 40%; false negative rate for pulmonary nodules dropped from 12% to 3.2% in clinical trials
Perplexity's search decomposes complex queries into sub-queries, runs parallel web retrievals, reranks across sources using cross-encoders, and synthesizes cited responses in < 3 seconds. Multi-hop reasoning: each sub-answer informs the next retrieval query. Every response includes numbered citations to source documents — the gold standard for attribution in production RAG.
✓ Result: 82% accuracy on knowledge-intensive queries vs. 67% for Google Search (independent evaluation); 4M+ daily active users
🌟 Core Principles
Every aspect of ai monitoring must be deliberately designed, not discovered after deployment. Document design decisions as ADRs with explicit rationale.
Apply ai monitoring practices consistently across all systems. Inconsistent application creates governance blind spots and makes incident investigation unpredictable.
AI Monitoring practices must demonstrably contribute to business outcomes: reduced downtime, faster delivery, lower operational cost, or improved compliance posture.
Quality of ai monitoring implementation must be measurable. Define specific metrics and collect evidence continuously — not only at audit or review time.
Standards for ai monitoring evolve as technology and threat landscapes change. Schedule quarterly reviews of applicable standards and update practices accordingly.
⚙️ Implementation Steps
Current State Assessment
Document the current state of ai monitoring practice: what is implemented, what is missing, what is inconsistent across teams. Use the governance/scorecards section for a structured assessment framework.
Gap Analysis Against Standards
Compare current state against the standards in this section and applicable frameworks (Industry Standards, Architecture Best Practices). Prioritize gaps by business impact and remediation effort.
Design the Target State
Define the target ai monitoring state: which patterns will be adopted, which anti-patterns eliminated, which governance mechanisms introduced. Express as a time-bound roadmap.
Incremental Implementation
Implement ai monitoring improvements incrementally: pilot with one team or system, measure outcomes, refine the approach, then expand. Avoid big-bang transformations.
Validate and Iterate
Measure the impact of implemented changes against defined success criteria. Incorporate lessons learned into the practice standards. Contribute improvements back to this library.

◈ Recommended Patterns
✦ Reference Architecture Adoption
Start from an established reference architecture for ai monitoring rather than designing from scratch. Adapt to organizational context rather than rebuilding proven foundations.
✦ Pattern Library Contribution
When your team solves a recurring ai monitoring problem with a novel approach, document it as a pattern for the library. This compounds organizational knowledge over time.
✦ Fitness Function Testing
Encode ai monitoring standards as automated architectural fitness functions — tests that run in CI/CD and fail builds when standards are violated. This makes governance continuous rather than periodic.
⛔ Anti-Patterns to Avoid
⛔ Standards Theater
Documenting ai monitoring standards in architecture policies that no one reads and no one enforces. Standards without automated validation or governance gates are not operational standards.
⛔ Copy-Paste Architecture
Adopting another organization's ai monitoring patterns wholesale without adapting to organizational context, team capability, or regulatory environment. Always adapt; never just copy.
🤖 AI Augmentation Extensions
LLM agents analyze design documents against ai monitoring standards, generating structured gap reports with cited evidence and suggested remediation approaches.
This section is optimized for vector ingestion into an AI-powered architecture assistant. Semantic search enables architects to retrieve relevant ai monitoring guidance through natural language queries.
