This curriculum spans the design and governance of model evaluation systems at the scale and complexity of a multi-team MLOps function, comparable to the technical and organizational rigor found in enterprise model risk management programs.

Module 1: Defining Evaluation Objectives within OKAPI Frameworks

Select whether evaluation focuses on predictive accuracy, operational efficiency, or compliance alignment based on stakeholder SLAs
Determine if model evaluation will support incremental retraining or full model replacement by assessing version drift thresholds
Establish evaluation frequency by balancing computational cost against business cycle requirements (e.g., daily batch vs. real-time triggers)
Decide on evaluation scope—whether to assess end-to-end pipeline performance or isolate model inference behavior
Map evaluation KPIs to business outcomes such as customer retention lift or fraud detection cost-per-case
Negotiate evaluation ownership between data science and MLOps teams to clarify responsibility for metric computation and reporting

Module 2: Data Integrity and Representativeness in Test Design

Implement temporal partitioning strategies to prevent future data leakage while preserving real-world deployment sequence
Validate test set representativeness using statistical distance metrics (e.g., Jensen-Shannon divergence) across key segments
Decide whether to use static holdout sets or dynamic shadow testing based on data drift velocity and labeling latency
Address class imbalance in evaluation by applying stratified sampling or cost-sensitive metrics without distorting business impact
Introduce synthetic edge cases into test data only when empirical failure logs are insufficient for rare event coverage
Document data lineage for evaluation sets to enable auditability and reproducibility across regulatory reviews

Module 3: Selection and Customization of Evaluation Metrics

Choose between F1-score and average precision based on label sparsity and operational recall requirements
Adapt ranking metrics (e.g., NDCG) to reflect business-defined item weighting in recommendation systems
Implement custom loss functions that incorporate asymmetric business costs (e.g., false negatives in credit underwriting)
Aggregate metrics across user cohorts using weighted averages that reflect revenue contribution, not equal sample sizes
Validate metric stability through bootstrapped confidence intervals before declaring performance shifts
Reject default metrics (e.g., accuracy) when baseline class distribution masks meaningful model degradation

Module 4: Operationalizing Offline Evaluation Pipelines

Design evaluation pipelines to reuse preprocessed features from training to ensure consistency and reduce compute
Version control evaluation code alongside model artifacts to enable retrospective performance analysis
Integrate evaluation into CI/CD workflows with conditional pass/fail gates based on metric degradation thresholds
Cache prediction outputs for large test sets to allow iterative metric experimentation without re-inference
Parallelize evaluation across model variants using distributed computing frameworks when latency constraints apply
Monitor resource consumption of evaluation jobs to prevent pipeline bottlenecks during peak deployment cycles

Module 5: Implementing Online Evaluation and A/B Testing

Allocate traffic between model variants using stratified randomization to maintain balance across user segments
Define primary and guardrail metrics to detect unintended side effects (e.g., increased latency or error rates)
Implement canary rollouts with automated rollback triggers based on real-time performance deviation
Isolate model impact from external factors by controlling for time-of-day, campaign effects, or market shifts
Use sequential testing methods to reduce experiment duration while maintaining statistical power
Enforce data retention policies for online test logs to comply with privacy regulations and storage budgets

Module 6: Monitoring for Model Degradation and Drift

Select drift detection method (e.g., PSI, KS-test) based on feature type and sensitivity to operational false alarms
Set adaptive thresholds for performance decay that account for seasonal variation and business growth trends
Differentiate between concept drift and data quality issues by cross-referencing with upstream data monitors
Trigger re-evaluation workflows based on volume-based schedules (e.g., per 100K new predictions) or event-based signals
Log prediction confidence distributions to detect silent failures in low-confidence regimes
Coordinate model monitoring alerts with incident response runbooks to ensure timely intervention

Module 7: Governance, Auditability, and Regulatory Compliance

Standardize evaluation reporting templates to support internal audit and external regulatory submissions
Implement role-based access controls on evaluation results to align with data classification policies
Archive evaluation artifacts (metrics, test sets, configurations) for minimum retention periods defined by legal teams
Document bias assessment procedures for high-risk models to satisfy fairness disclosure requirements
Reconcile model performance discrepancies between development, staging, and production environments
Conduct third-party validation of evaluation methodology for models used in regulated decisioning processes

Module 8: Scaling Evaluation Across Model Portfolios

Develop centralized evaluation registry to track metric trends across hundreds of models in production
Prioritize evaluation depth based on model risk tier, with high-impact models receiving full diagnostic suites
Automate baseline comparisons against historical and challenger models using standardized benchmark datasets
Implement meta-evaluation to assess the reliability of evaluation systems themselves over time
Distribute evaluation workload across teams using domain-specific playbooks for fraud, NLP, forecasting, etc.
Negotiate shared evaluation infrastructure budgets between business units to avoid redundant tooling
