This curriculum spans the technical, operational, and governance dimensions of predictive vehicle maintenance at a scale and depth comparable to a multi-phase organisational rollout, integrating data engineering, model lifecycle management, and workflow alignment across fleet operations.
Module 1: Defining Predictive Maintenance Objectives and KPIs
- Select appropriate failure modes to target based on historical downtime logs and repair cost analysis
- Determine whether to prioritize mean time between failures (MTBF) or reduction in unplanned downtime as the primary KPI
- Negotiate data access requirements with fleet operations teams to align with maintenance workflow cycles
- Decide on asset coverage scope: high-value vehicles only or full fleet inclusion based on ROI thresholds
- Establish baseline performance metrics using 12 months of historical repair and sensor data
- Define acceptable false positive rates for alerts considering technician dispatch costs
- Integrate maintenance scheduling constraints into objective design to avoid conflicting work orders
- Document stakeholder agreement on success criteria for model validation and handoff
Module 2: Vehicle Data Acquisition and Sensor Integration
- Select CAN bus data channels to extract based on correlation with known failure indicators
- Evaluate retrofitting legacy vehicles with IoT sensors versus relying on OEM telematics only
- Configure edge devices to buffer and transmit data under intermittent cellular connectivity

- Implement data normalization rules for mixed fleets with heterogeneous sensor configurations
- Design payload compression strategies to reduce transmission costs across large fleets
- Validate timestamp synchronization across vehicle clocks and backend ingestion systems
- Establish fallback mechanisms for missing or corrupted data streams during transit
Module 3: Data Preprocessing and Feature Engineering
- Develop vehicle-specific baselines for engine temperature and vibration to enable cross-fleet comparison
- Construct rolling window features for oil pressure and RPM to detect gradual degradation trends
- Impute missing sensor values using vehicle-specific interpolation rather than fleet-wide averages
- Segment data by operating conditions (e.g., urban vs. highway) to reduce environmental noise
- Apply domain-aware outlier filtering to exclude data from known faulty sensors
- Generate derived features such as brake cycle counts and idle time ratios from raw signals
- Implement version-controlled feature pipelines to ensure reproducibility across model updates
- Balance computational load by precomputing features at ingestion versus on-demand
Module 4: Model Selection and Training Strategy
- Compare survival models against binary classifiers for time-to-failure prediction accuracy
- Decide whether to train per-vehicle models or shared fleet-wide models based on heterogeneity
- Allocate training data by stratifying across vehicle age, model, and usage intensity
- Implement early stopping criteria using validation set performance on rare failure events
- Choose between XGBoost and neural networks based on interpretability and latency requirements
- Address class imbalance using cost-sensitive learning rather than oversampling rare failures
- Train models incrementally to adapt to new vehicle models entering the fleet
- Validate model convergence using loss trajectories across multiple vehicle clusters
Module 5: Model Validation and Performance Benchmarking
- Design time-based validation splits that prevent data leakage from future repairs
- Evaluate precision-recall curves across different failure types due to varying criticality
- Conduct backtesting using historical data to simulate real-time model performance
- Compare model outputs against existing scheduled maintenance intervals for cost impact
- Measure alert lead time distribution to ensure actionable intervention windows
- Validate model stability across seasonal operating conditions and geographic regions
- Perform ablation studies to quantify contribution of individual sensor inputs
- Document model drift thresholds that trigger retraining workflows
Module 6: Deployment Architecture and Real-Time Inference

Module 7: Alerting, Workflow Integration, and Technician Handoff
- Design multi-tier alert severity levels based on predicted failure probability and impact
- Integrate alert routing with existing CMMS systems to create work orders automatically
- Define escalation paths for high-risk predictions that bypass standard scheduling
- Calibrate alert frequency to prevent technician alert fatigue and desensitization
- Include diagnostic rationale in alerts to support technician decision-making
- Log technician disposition of alerts to feed back into model recalibration
