Description

This curriculum spans the design and execution of lean inventory systems across procurement, production, and logistics, comparable in scope to a multi-workshop operational transformation program addressing end-to-end material flow, cross-functional alignment, and sustained process control.

Module 1: Foundations of Lean Inventory Principles

Define inventory categories (raw materials, WIP, finished goods) within a value stream map and assess their alignment with customer takt time.
Select which SKUs to classify under ABC analysis based on annual consumption value and adjust safety stock policies accordingly.
Establish a baseline for inventory turns by calculating current stock levels against COGS and identify outliers for root cause analysis.
Implement FIFO lanes in storage areas where product shelf life or engineering changes make rotation critical.
Negotiate with suppliers to shift from lot-size-based pricing to volume-based agreements that support smaller, more frequent deliveries.
Decide whether to adopt a pull-based system for high-variability items or maintain push logic for stable, high-volume components.

Module 2: Demand Forecasting and Pull System Design

Configure Kanban card quantities by factoring in lead time variability, container size, and replenishment frequency.
Adjust forecast models monthly using actual sales data, incorporating promotions and seasonality while minimizing bullwhip effects.
Design shared supermarket buffers between adjacent work cells to decouple processes without increasing total inventory.
Implement dual-card Kanban systems (production and move cards) in high-mix environments to separate production authorization from material transfer.
Validate forecast accuracy by calculating MAPE across product families and recalibrate models for items exceeding error thresholds.
Determine reorder points for consignment inventory by analyzing supplier lead time performance and internal consumption patterns.

Module 3: Supplier Integration and JIT Replenishment

Qualify suppliers for JIT delivery based on on-time performance, quality defect rates, and geographic proximity.
Negotiate delivery windows within a 2-hour time slot and align inbound logistics with production line consumption rates.
Implement milk-run logistics routes with third-party carriers to consolidate small shipments from multiple suppliers.
Establish supplier-held inventory agreements with clear ownership transfer triggers at point of use.
Monitor supplier lead time variability using control charts and initiate corrective actions when process capability falls below Cpk 1.33.
Enforce standard containerization requirements across suppliers to reduce handling time and staging space.

Module 4: Inventory Visibility and Technology Enablement

Deploy barcode or RFID scanning at key material handoff points to maintain real-time inventory accuracy above 98%.
Integrate ERP and MES systems to synchronize inventory transactions and eliminate manual reconciliation efforts.
Configure WMS binning logic to enforce putaway rules that support FIFO and minimize travel time.
Implement cycle counting routines focused on high-turnover SKUs with daily counts replacing full physical inventories.
Design dashboard alerts for stockouts, overstock conditions, and Kanban signal delays using live system data.
Validate data integrity by auditing system-on-hand versus physical counts in high-value storage zones quarterly.

Module 5: Waste Reduction and Inventory Optimization

Conduct monthly inventory health reviews to identify and disposition obsolete, excess, or slow-moving stock.
Apply SMED techniques to reduce changeover times and enable smaller batch sizes, directly lowering WIP inventory.
Implement heijunka boards to level production volume and mix, reducing the need for finished goods buffers.
Establish standard work instructions for material handlers to minimize overretrieval and misplacement.
Redesign product platforms to increase commonality of components and reduce SKU proliferation.
Calculate carrying cost per item category (including capital, storage, obsolescence) to prioritize reduction efforts.

Module 6: Performance Measurement and Continuous Improvement

Track inventory turns by product family and set annual improvement targets tied to working capital goals.
Measure Kanban replenishment cycle time and identify bottlenecks in signal processing or material flow.
Conduct Gemba walks to observe material movement and validate that inventory levels match visual management standards.
Use Pareto analysis to focus improvement efforts on the 20% of SKUs contributing to 80% of inventory value.
Review supplier delivery performance monthly and initiate joint improvement plans for those below 95% on-time rate.
Update standard inventory metrics in performance scorecards for operations and supply chain teams quarterly.

Module 7: Change Management and Organizational Alignment

Align inventory reduction goals with finance through shared working capital objectives and reporting structures.
Train production supervisors to manage output based on pull signals rather than forecast push schedules.
Revise incentive systems to reward inventory accuracy and flow efficiency over machine utilization.
Facilitate cross-functional workshops to resolve conflicts between sales (demand variability) and operations (inventory control).
Document and socialize standard responses for supply disruptions to prevent reactive overstocking.
Establish a material flow team with representatives from procurement, production, and logistics to sustain improvements.
