Description

This curriculum spans the technical and organisational complexity of a multi-workshop operational redesign, addressing the same interdependencies between forecasting, network strategy, and cross-functional governance that arise in enterprise-wide service parts transformation programs.

Module 1: Demand Forecasting and Statistical Modeling

Selecting between intermittent demand models (Croston, SBA, TSB) based on part lifecycle stage and historical transaction sparsity.
Adjusting forecast parameters (alpha, beta) in exponential smoothing models to balance responsiveness and stability for low-turn parts.
Integrating engineering change notifications into forecasting logic to preempt demand spikes from retrofit campaigns.
Validating forecast accuracy using holdout samples and selecting error metrics (MAPE, WMAPE, service level deviation) aligned with business objectives.
Handling zero-demand periods in forecasting engines without distorting safety stock calculations.
Managing forecast overrides from field service leads while maintaining audit trails and model integrity.

Module 2: Inventory Stratification and Classification

Defining service-criticality tiers using downtime cost data from operations, not just sales volume or part cost.
Revising ABC-XYZ classifications quarterly based on actual field failure rates and repair cycle times.
Allocating inventory budgets across locations using marginal value of service improvement, not equal percentage cuts.
Identifying slow-moving but high-impact parts that require strategic stocking despite low turnover.
Implementing dynamic classification rules that adjust for seasonality and product end-of-life phases.
Resolving conflicts between financial inventory reduction targets and service-level requirements for mission-critical spares.

Module 3: Network Design and Stocking Location Strategy

Evaluating trade-offs between regional consolidation and local stocking based on mean time to repair (MTTR) requirements.
Determining optimal number of echelons in a multi-tier network considering customs delays and transportation reliability.
Placing buffer stock at forward stocking locations based on proximity to high-density service zones, not just volume.
Assessing vendor-managed inventory (VMI) agreements for high-cost, low-variability parts with reliable suppliers.
Modeling transshipment feasibility between depots under service-level agreements and freight cost constraints.
Deciding when to use third-party logistics (3PL) hubs versus company-owned facilities based on lead time variability, not just cost.

Module 4: Supplier and Procurement Lead Time Management

Negotiating consignment agreements for long-lead critical components to shift inventory ownership without sacrificing availability.
Mapping supplier delivery performance by part number to identify root causes of variability (customs, production batching, quality holds).
Implementing blanket purchase orders with scheduled releases to reduce order processing time without overstocking.
Enforcing supplier scorecards that include on-time delivery, lead time accuracy, and responsiveness to expedite requests.
Managing dual-sourcing strategies for single-source parts with geopolitical or capacity risks.
Integrating supplier production schedules into inventory planning systems for make-to-order components.

Module 5: Order Expediting and Dynamic Prioritization

Designing escalation protocols for high-priority orders based on equipment downtime severity and contractual SLAs.
Implementing a centralized order expediting dashboard with real-time visibility into shipment status and delays.
Allocating limited expediting resources using a scoring model that weights customer impact, revenue at risk, and repair backlog.
Tracking the cost of expedited freight to evaluate return on investment and identify systemic delays.
Coordinating with transportation providers to pre-clear customs documentation for urgent shipments.
Preventing over-expediting by analyzing root causes of recurring delays instead of treating symptoms.

Module 6: Spare Parts Provisioning in Product Lifecycle Transitions

Calculating end-of-life buy quantities using failure curve projections and remaining installed base estimates.
Managing cannibalization programs for obsolete parts while maintaining traceability and compliance.
Aligning new product introduction (NPI) spare provisioning with early field failure data, not just engineering estimates.
Transferring inventory between legacy and new platforms during technology transitions to avoid stranded stock.
Updating bill-of-materials (BOM) accuracy in service systems to reflect field modifications and retrofits.
Coordinating with design engineering to influence serviceability and part commonality in next-generation products.

Module 7: Performance Monitoring and Lead Time Analytics

Measuring actual versus planned lead time by segmenting data by part type, supplier, and shipping route.
Establishing control thresholds for lead time variation and triggering root cause analysis when exceeded.
Using time-in-status tracking to identify bottlenecks in procurement, customs, or internal transfer processes.
Correlating inventory turnover with service level achievement to assess trade-offs in stocking policies.
Reporting lead time reduction progress using normalized metrics that account for external factors like port congestion.
Integrating lead time KPIs into operational reviews with supply chain, service, and procurement leadership.

Module 8: Cross-Functional Integration and Change Management

Aligning service parts planning cycles with financial reporting periods to support budget forecasting and variance analysis.
Resolving conflicts between service-level targets and working capital objectives through joint governance forums.
Integrating field service technician feedback into parts availability dashboards and shortage reporting.
Implementing change management protocols for updating stocking policies after network or supplier changes.
Training procurement teams on service-critical part requirements to reduce misaligned sourcing decisions.
Documenting decision rights for inventory investment approvals across service, supply chain, and finance functions.
