This curriculum spans the technical and operational rigor of a multi-workshop inventory diagnostics program, addressing the same demand forecasting, stocking logic, and system integration challenges encountered in live service parts networks supporting complex equipment fleets.

Module 1: Demand Forecasting for Intermittent Service Parts

• Select whether to use Croston’s method or Syntetos-Boylan approximation based on historical demand sparsity and business tolerance for over-forecasting.
• Decide on the length of the historical lookback period for forecasting models, balancing responsiveness to recent changes against stability in low-demand parts.
• Implement demand filtering rules to exclude one-time spikes (e.g., disaster recovery events) from baseline forecasts without masking emerging failure trends.
• Integrate engineering change notifications into forecasting logic to adjust for parts being phased out or newly introduced.
• Configure forecast override workflows that allow field service managers to input localized failure intelligence while preventing arbitrary adjustments.
• Establish forecast accuracy KPIs (e.g., Mean Absolute Scaled Error) specific to intermittent demand and define thresholds for model retraining.

Module 2: Inventory Optimization and Stocking Policies

• Determine service level targets per part category (e.g., 98% for critical spares vs. 90% for non-critical) based on equipment downtime cost and repair lead time.
• Select between min/max, reorder point, or periodic review systems depending on supplier reliability and internal replenishment cycle constraints.
• Calculate safety stock levels using empirical lead time variability data rather than supplier quoted lead times to avoid chronic under-provisioning.
• Implement multi-echelon inventory policies that differentiate stocking strategies between central depots, regional hubs, and forward stocking locations.
• Define obsolescence triggers based on phase-out schedules and set write-down protocols for slow-moving inventory.
• Adjust stocking decisions dynamically when parts are shared across multiple equipment models with divergent lifecycle stages.

Module 3: Supplier and Lead Time Management

• Negotiate supplier penalty clauses for lead time variability while assessing the feasibility of enforcement in sole-source scenarios.
• Map actual inbound logistics performance (transit time, customs delays) to inventory models instead of relying on supplier lead time commitments.
• Decide whether to dual-source high-risk components based on geopolitical exposure and minimum order quantity constraints.
• Implement expedited procurement workflows with pre-approved cost thresholds for emergency part sourcing during critical outages.
• Integrate supplier quality defect rates into replenishment calculations to account for incoming part rejection and reordering needs.
• Establish lead time segmentation rules that trigger different stocking policies for short (<7 days), medium (8–30 days), and long (>30 days) lead time parts.

Module 4: Parts Classification and Criticality Analysis

• Design a criticality scoring model incorporating equipment downtime cost, safety impact, and repair time to prioritize inventory allocation.
• Classify parts using a hybrid ABC-XYZ matrix that combines value consumption with demand variability to guide stocking intensity.
• Update classification rules quarterly to reflect changes in installed base, service contracts, and field failure trends.
• Apply different inventory policies to parts classified as “strategic” due to single-source dependency or long lead times.
• Exclude non-repairable consumables from criticality models that assume repair cycle return and reuse.
• Align classification outcomes with warehouse slotting strategies to reduce technician pick time for high-criticality items.

Module 5: Service Level Agreements and Operational Trade-offs

• Translate SLA response time commitments (e.g., 4-hour onsite repair) into part availability requirements at specific service locations.
• Quantify the cost of stockouts in terms of SLA penalties, customer retention impact, and technician idle time to justify inventory investment.
• Allocate limited inventory across regions using a weighted scoring model based on contract value, strategic accounts, and failure exposure.
• Implement dynamic rationing rules during shortages that prioritize high-revenue equipment or safety-critical repairs.
• Balance inventory costs against field service productivity by measuring technician dispatch success rates tied to part availability.
• Define escalation paths for stockout events that trigger cross-location transfers, temporary substitutions, or customer communication protocols.

Module 6: Data Integrity and System Integration

Enforce part master data governance rules to eliminate duplicates, incorrect units of measure, and inconsistent naming across ERP and CMMS systems.

Reconcile physical inventory counts with system records monthly to correct discrepancies that distort demand and reorder logic.

Map failure codes from service tickets to specific parts to improve root cause-based forecasting accuracy.

Integrate reverse logistics data (return, repair, and core tracking) into net demand calculations for repairable components.

Validate lead time fields in procurement systems against actual purchase order receipt timestamps to maintain model integrity.

Implement data quality dashboards that flag missing or stale fields (e.g., unassigned criticality) impacting inventory decisions.

Module 7: Performance Monitoring and Continuous Improvement

• Track stockout frequency and duration by part, location, and equipment type to identify systemic supply chain vulnerabilities.
• Calculate inventory turnover and carrying cost per criticality tier to assess capital efficiency and identify overstocking.
• Conduct root cause analysis on chronic stockouts using a structured framework (e.g., 5 Whys) to distinguish demand, supply, or data issues.
• Review supplier performance quarterly using on-time delivery rate, quality yield, and lead time accuracy metrics.
• Adjust safety stock parameters based on observed stockout incidents and changes in operational risk exposure.
• Facilitate cross-functional inventory review meetings with service, procurement, and finance to align on trade-offs and corrective actions.

Module 8: Technology Enablement and Process Automation

• Evaluate whether to deploy advanced inventory optimization software versus extending existing ERP planning modules based on modeling complexity and data volume.
• Automate min/max recalibration using machine learning models trained on historical stockouts, seasonality, and equipment retirement data.
• Implement barcode or RFID tracking at service depots to reduce manual entry errors and improve inventory visibility.
• Configure automated alerts for parts approaching obsolescence or exceeding predefined stock-to-demand ratios.
• Integrate IoT sensor data from equipment fleets to trigger proactive part reservations before predicted failures occur.
• Design exception management dashboards that highlight parts requiring manual review due to forecast-actual deviations or supply disruptions.
