This curriculum spans the full lifecycle of data management in production ML systems, equivalent in scope to a multi-workshop program embedded within an enterprise data science transformation, addressing technical, governance, and collaboration challenges encountered when scaling ML across business units.
Module 1: Defining Data Requirements for Business-Centric ML Use Cases
- Align data scope with key performance indicators (KPIs) tied to business outcomes, such as customer retention or operational cost reduction.
- Negotiate data access rights with legal and compliance teams when sourcing customer interaction logs from legacy CRM systems.
- Determine whether real-time or batch data collection better supports the latency requirements of a fraud detection model.
- Select data sources based on historical coverage depth, such as five years of transaction records to capture seasonal trends.
- Document data lineage expectations early to ensure traceability from raw ingestion to model inference.
- Balance data richness against collection cost when deciding whether to license third-party market data for demand forecasting.
- Establish data ownership roles across business units to prevent duplication and inconsistent definitions.
Module 2: Designing Scalable and Secure Data Ingestion Pipelines
- Choose between change data capture (CDC) and scheduled ETL jobs based on source system capabilities and data freshness needs.
- Implement schema validation at ingestion to reject malformed records from IoT sensors before they pollute downstream systems.
- Configure retry logic and dead-letter queues in streaming pipelines to handle transient API failures from external vendors.
- Encrypt sensitive fields (e.g., PII) during transit and at rest using customer-managed keys in cloud storage.
- Size compute resources for peak load during month-end financial data ingestion without over-provisioning.
- Monitor ingestion latency to detect upstream system degradation before it impacts model training schedules.
- Integrate ingestion logs with centralized observability platforms for audit and troubleshooting.
Module 3: Data Quality Assessment and Remediation Strategies
- Define data quality rules per field, such as rejecting customer age values outside 18–120 for a lending model.
- Quantify missing data patterns across time series to determine if imputation introduces bias in forecasting.
- Use statistical profiling to detect silent data drift, such as a sudden drop in GPS signal frequency from delivery vehicles.
- Escalate data quality issues to source system owners with evidence, such as duplicate order IDs in transaction feeds.
- Implement automated data validation checks in CI/CD pipelines before promoting datasets to production.
- Decide whether to exclude or correct outlier records in supply chain data based on operational context.
- Track data quality metrics over time to measure improvement after upstream system fixes.
Module 4: Feature Engineering and Management at Scale
- Version feature definitions in a shared repository to ensure consistency between training and serving environments.
- Optimize feature computation latency by pre-aggregating daily sales totals instead of recalculating at inference.
- Apply log transformations to skewed financial variables before feeding them into regression models.
- Cache frequently used features in a feature store to reduce redundant computation across multiple models.
- Enforce access controls on sensitive features, such as customer credit scores, using role-based policies.
- Monitor feature drift by comparing statistical distributions in production versus training data.
- Document business logic behind derived features, such as "customer engagement score," for audit and compliance.
Module 5: Building and Governing a Centralized Feature Store
- Select between online and offline feature stores based on model latency requirements (e.g., real-time recommendations).
- Define SLAs for feature availability and freshness, such as 99.9% uptime for features used in credit scoring.
- Implement feature access approval workflows for regulated use cases involving health or financial data.
- Archive unused features to reduce storage costs and simplify discovery for data scientists.
- Integrate feature lineage tracking to support regulatory audits and root cause analysis.
- Standardize feature naming conventions across teams to prevent duplication and confusion.
- Monitor feature store query patterns to identify performance bottlenecks and optimize indexing.
Module 6: Managing Data Versioning and Reproducibility
- Use content-addressed storage to version large datasets and ensure exact replication of training environments.
- Link dataset versions to specific model training runs in a metadata registry for auditability.
- Resolve conflicts when multiple teams modify the same dataset by implementing branching and merge strategies.
- Automate data snapshotting before major model retraining cycles to enable rollback if needed.
- Store data preprocessing code in version control alongside raw data references to ensure reproducible pipelines.
- Archive outdated dataset versions according to data retention policies while preserving access for compliance.
- Track dependencies between data versions and model versions to assess impact of data changes.
Module 7: Implementing Data Governance and Compliance Controls
- Classify data assets by sensitivity level (e.g., public, internal, confidential) to enforce access policies.
- Implement data masking for PII fields in non-production environments used for model development.
- Conduct data protection impact assessments (DPIAs) for models processing personal health information.
- Log all data access requests and approvals for regulatory reporting under GDPR or CCPA.
- Establish data retention schedules for training datasets to comply with legal hold requirements.
- Coordinate with legal teams to document data provenance for third-party licensed datasets.
- Enforce data minimization by removing irrelevant fields before model training to reduce compliance risk.
Module 8: Monitoring Data Pipelines and Model Data Dependencies
- Set up alerts for pipeline failures, such as a missing daily file from an external supplier.
- Measure and track data freshness to ensure features are updated within required time windows.
- Correlate data anomalies with model performance degradation using shared timestamps and logs.
- Deploy shadow pipelines to validate new data transformations before switching live traffic.
- Monitor schema evolution in source systems to detect breaking changes that affect feature computation.
- Use data contracts to specify expected formats and constraints between data producers and consumers.
- Integrate data health metrics into model monitoring dashboards for holistic observability.
Module 9: Enabling Cross-Functional Collaboration and Data Democratization
- Develop a searchable data catalog with business-friendly metadata to improve discoverability.
- Train business analysts to use self-service tools for accessing approved datasets without SQL.
- Facilitate data review sessions between data scientists and domain experts to validate assumptions.
- Implement data access request workflows that balance speed with security and compliance.
- Standardize data dictionaries across departments to align on definitions like "active customer."
- Host data quality retrospectives to share lessons from pipeline failures or model inaccuracies.
- Measure adoption of shared data assets to justify continued investment in data infrastructure.
