This curriculum spans the design, execution, and governance of batch processing in lean operations, comparable in scope to a multi-workshop operational readiness program that integrates process engineering, shop floor control, and cross-functional alignment.
Module 1: Foundations of Batch Processing in Lean Systems
- Selecting appropriate batch sizes based on demand variability and changeover time using SMED analysis.
- Mapping batch processing steps in value stream maps to identify non-value-added delays between operations.
- Integrating batch logic with takt time to align production pace with customer demand.
- Deciding between fixed-interval and fixed-quantity batching based on material flow stability.
- Assessing the impact of batch processing on WIP inventory levels across shared work centers.
- Documenting batch process parameters in standard work instructions to ensure consistency across shifts.
Module 2: Process Design and Flow Optimization
- Redesigning batch sequences to minimize backflow and cross-traffic in cellular layouts.
- Implementing FIFO lanes between batch operations to control release timing and prevent overproduction.
- Configuring buffer zones at batch transition points to absorb minor disruptions without halting flow.
- Calculating optimal batch transfer quantities between processes using economic transfer quantity (ETQ) models.
- Validating flow performance through time studies comparing batch vs. one-piece flow throughput.
- Introducing poka-yoke at batch loading stations to prevent incorrect part or quantity inputs.
Module 3: Changeover Reduction and SMED Implementation
- Conducting videotaped changeover observations to classify internal and external setup activities.
- Converting internal setup tasks to external by pre-staging tooling, jigs, and materials.
- Standardizing fasteners and adjustment mechanisms to reduce fine-tuning time during changeovers.
- Developing setup checklists and visual aids for operators to reduce variability in changeover execution.
- Measuring changeover time reduction impact on minimum economical batch size.
- Coordinating cross-functional teams (maintenance, engineering, operations) to implement quick die-change systems.
Module 4: Inventory and Capacity Management
- Setting dynamic batch sizes based on real-time capacity constraints and backlog levels.
- Calculating safety stock requirements for batch processes with variable cycle times.
- Allocating shared equipment time across product families using finite capacity scheduling.
- Monitoring inventory aging reports to detect over-batching in slow-moving SKUs.
- Adjusting batch frequency in response to supplier lead time fluctuations.
- Using heijunka boards to level batch production volume and mix over time.
Module 5: Quality Control in Batch Operations
- Implementing first/last piece inspection protocols at the start and end of each batch.
- Integrating in-line gauging systems to detect dimensional drift during extended batch runs.
- Isolating non-conforming batches and initiating containment actions before downstream processing.
- Mapping defect rates by batch number to identify recurring process instability patterns.
- Designing sampling plans for batch release when 100% inspection is impractical.
- Linking batch records to traceability systems for compliance in regulated environments.
Module 6: Performance Measurement and Continuous Improvement
- Tracking OEE for batch equipment with separate loss categorization for setup, idling, and minor stops.
- Using batch yield reports to prioritize kaizen events on high-volume, low-yield processes.
- Conducting root cause analysis on batch rework trends using 5-why or fishbone diagrams.
- Benchmarking batch cycle times across shifts to identify operator-driven inefficiencies.
- Updating standard work as improvements reduce batch processing times.
- Integrating batch performance data into daily management review boards.
Module 7: Technology Integration and Automation
- Programming batch logic in PLCs to automate material release based on batch completion signals.
- Configuring ERP systems to generate batch production orders with correct routing and BOMs.
- Using barcode scanning to validate batch material consumption and labor tracking.
- Implementing batch-level data collection in MES for real-time process monitoring.
- Automating batch reporting for regulatory submissions using structured data exports.
- Integrating batch scheduling algorithms with finite capacity planning tools to reduce conflicts.
Module 8: Organizational Alignment and Change Management
- Revising performance metrics for supervisors to discourage large batch incentives.
- Training material handlers on batch sequencing to prevent misrouted or early deliveries.
- Facilitating cross-departmental workshops to align procurement batch sizes with production needs.
- Establishing escalation paths for batch delays that impact downstream operations.
- Documenting batch process ownership to clarify accountability for improvements.
- Rolling out pilot batch reductions in low-risk areas to demonstrate feasibility before site-wide deployment.
