Description

This curriculum spans the technical, operational, and governance dimensions of deploying predictive maintenance systems, comparable in scope to a multi-phase organisational rollout involving data engineering teams, fleet operations, and compliance functions.

Module 1: Defining Predictive Maintenance Objectives and Success Metrics

Selecting failure modes to prioritize based on downtime cost, safety impact, and detectability through sensor data
Establishing operational KPIs such as mean time between failures (MTBF), reduction in unplanned downtime, and spare parts inventory turnover
Aligning predictive model outputs with maintenance workflows, including integration into CMMS (Computerized Maintenance Management Systems)
Determining acceptable false positive and false negative rates in alerts based on technician capacity and risk tolerance
Defining data-driven thresholds for actionable alerts versus monitoring-only conditions
Mapping stakeholder responsibilities across engineering, operations, and data science teams for model ownership and escalation
Deciding whether to target component-level or system-level failure prediction based on data availability and maintenance procedures
Setting performance baselines using historical failure logs and maintenance records prior to model deployment

Module 2: Sensor Integration and Telemetry Architecture

Selecting onboard sensors (vibration, temperature, pressure, acoustics) based on failure mode sensitivity and retrofit feasibility
Designing data sampling rates and transmission intervals to balance diagnostic resolution with network bandwidth and storage costs
Implementing edge preprocessing to reduce data volume (e.g., FFT on vibration data) before transmission
