Analogy: model governance is like air traffic control for models.

class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions (FAQs)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What level of governance is appropriate for small startups?<\/h3>\n\n\n\n<p>Startups should adopt risk-based governance: lightweight controls for prototypes, stricter for any customer-facing or revenue-impacting models.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I measure model drift without labels?<\/h3>\n\n\n\n<p>Use unsupervised drift measures like distributional distance metrics and proxy SLIs; plan periodic labeling for reconciliation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can governance be fully automated?<\/h3>\n\n\n\n<p>Many parts can be automated, but human approvals remain necessary for high-risk decisions and ethical reviews.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do SRE and ML teams collaborate on on-call?<\/h3>\n\n\n\n<p>Define shared playbooks, clear responsibilities, and joint runbooks; include ML engineers in rotation for model incidents.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How often should models be retrained?<\/h3>\n\n\n\n<p>It varies; use drift detection, label arrival rates, and business KPIs to trigger retraining rather than fixed cadence.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What telemetry is mandatory for every model?<\/h3>\n\n\n\n<p>At minimum: model_version, request_id, latency percentiles, error counts, input feature hashes, and prediction outputs sampling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to handle privacy in governance?<\/h3>\n\n\n\n<p>Use data minimization, pseudonymization, DP or federated learning where applicable, and strict access controls.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Are registries necessary?<\/h3>\n\n\n\n<p>Yes for production models requiring reproducibility and auditability; lightweight setups can start with artifact stores and metadata.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to prevent bias during retraining?<\/h3>\n\n\n\n<p>Include fairness constraints in validation, use representative data, and require fairness pass before deployment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is acceptable SLO for model accuracy?<\/h3>\n\n\n\n<p>Depends on business impact; translate accuracy into business KPIs and set conservative initial targets, then iterate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do you estimate the cost of governance?<\/h3>\n\n\n\n<p>Estimate people time for audits, infra for telemetry retention, and tooling licenses; tie to risk avoided for justification.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to handle third-party models?<\/h3>\n\n\n\n<p>Treat as black-box artifacts with strict runtime monitoring, contract tests, and legal review for data usage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to scale governance across teams?<\/h3>\n\n\n\n<p>Create platform-level controls, standard templates, and policy-as-code so teams self-serve within safe boundaries.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What logs should be preserved for postmortem?<\/h3>\n\n\n\n<p>Preserve prediction logs, input feature snapshots (with PII removed), deployment metadata, and system-level traces.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to apply governance in serverless environments?<\/h3>\n\n\n\n<p>Enforce policy in CI, instrument functions for telemetry, and ensure data privacy checks before model use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When should I involve legal and compliance?<\/h3>\n\n\n\n<p>Early for regulated domains or customer-impacting models; include them in defining acceptable thresholds and evidence needs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to handle legacy models with no metadata?<\/h3>\n\n\n\n<p>Start by defending production surface: add telemetry wrappers, capture current inputs, and gradually onboard to registry.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is an error budget for models?<\/h3>\n\n\n\n<p>An allowance for SLI breaches within a period used to govern experiments and rollouts; define in context of business impact.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Model governance is an operational necessity for scaling safe, reliable, and compliant AI. It blends policy, automation, telemetry, and human workflows to manage risk while preserving velocity.<\/p>\n\n\n\n<p>Next 7 days plan (5 bullets):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Day 1:
