This curriculum spans the design and coordination of enterprise-wide JIT systems, comparable in scope to a multi-phase operational transformation engaging procurement, production, and logistics teams across multiple sites.
Module 1: Foundations of Just-In-Time in Lean Operations
- Selecting value streams appropriate for JIT implementation based on demand stability and supplier reliability
- Mapping current-state material and information flows to identify non-value-added delays in production scheduling
- Establishing takt time alignment across workstations to match customer demand rates
- Defining pull signals (e.g., kanban cards, electronic triggers) for each process segment
- Conducting changeover time assessments to evaluate feasibility of small-lot production
- Identifying constraints in information flow that prevent real-time response to downstream demand
Module 2: Supplier Integration and External JIT Coordination
- Negotiating delivery frequency agreements with suppliers to support twice-daily or hourly replenishment
- Implementing vendor-managed inventory (VMI) with shared demand forecasting data
- Designing inbound logistics routes for milk runs with fixed schedules and standardized containers
- Enforcing supplier quality certifications to reduce incoming inspection requirements
- Developing contingency plans for supplier disruptions without reverting to bulk inventory
- Standardizing communication protocols for order changes, including escalation paths for urgent adjustments
Module 3: Kanban System Design and Deployment
- Calculating optimal kanban card quantities based on container size, lead time, and safety factor
- Choosing between single-card and dual-card systems for mixed-model production lines
- Designing physical vs. electronic kanban based on shop floor technology readiness
- Integrating kanban signals with ERP systems to maintain data accuracy
- Training team leaders to detect and respond to kanban signal backlogs
- Adjusting kanban levels quarterly based on consumption trends and seasonal demand shifts
Module 4: Production Line Balancing and Flow Optimization
- Rebalancing work content across stations after reducing batch sizes to maintain pace
- Implementing poka-yoke devices to enable immediate defect detection in continuous flow
- Relocating work cells to minimize transport distance and handling between operations
- Standardizing work instructions to support operator flexibility in JIT environments
- Monitoring work-in-process (WIP) levels hourly to detect flow interruptions
- Adjusting staffing levels dynamically based on real-time production pull signals
Module 5: Inventory Reduction and Buffer Management
- Setting dynamic safety stock levels based on supplier performance metrics and lead time variability
- Phasing out buffer stocks in stages while monitoring for production stoppages
- Implementing FIFO lanes with visual controls to prevent stock aging
- Tracking inventory turns by SKU to prioritize JIT rollout in high-velocity lines
- Auditing supermarket replenishment cycles to prevent overstocking
- Using andon signals to trigger expedited restocking when buffer levels fall below thresholds
Module 6: Performance Measurement and Continuous Improvement
- Defining and tracking lead time from order release to shipment in mixed-model environments
- Calculating OEE with downtime categorized by JIT-related causes (e.g., material shortages)
- Conducting weekly gemba walks to observe pull system adherence and identify deviations
- Using process behavior charts to distinguish common-cause from special-cause variation in delivery performance
- Integrating JIT KPIs into daily huddle meetings at the cell level
- Driving kaizen events focused on reducing material handling time between processes
Module 7: Risk Mitigation and System Resilience
- Designing flexible capacity buffers (e.g., cross-trained operators) instead of inventory buffers
- Validating dual-sourcing strategies for critical components without increasing lead times
- Implementing real-time supplier performance dashboards to preempt disruptions
- Testing emergency response protocols for transportation delays using simulated scenarios
- Assessing impact of demand spikes on pull system stability using historical data
- Updating risk registers quarterly to reflect changes in geopolitical, logistical, or supplier conditions
Module 8: Scaling and Sustaining JIT Across the Enterprise
- Developing rollout roadmaps for JIT expansion across multiple plants with varying maturity levels
- Aligning incentive systems to reward flow efficiency over individual machine utilization
- Standardizing kanban rules and container specifications enterprise-wide
- Integrating JIT performance data into enterprise business intelligence platforms
- Establishing center of excellence roles to audit and support JIT implementation consistency
- Updating standard operating procedures to reflect JIT practices in procurement, planning, and production
