Description

This curriculum spans the design and execution of multi-workshop continuous improvement programs, integrating Lean and Six Sigma techniques to address lead time challenges across manufacturing, service delivery, and supply chain functions.

Module 1: Foundations of Lead Time in Operational Systems

Define lead time boundaries in a cross-functional process by aligning start and end points with customer request and delivery confirmation, avoiding arbitrary departmental cutoffs.
Map discrete lead time components (processing, queue, setup, move, inspection) in a manufacturing cell using direct observation and time-stamped work logs.
Integrate lead time measurement into existing ERP data fields by modifying transaction codes to capture timestamps at key process gates.
Resolve discrepancies between accounting cycle times and actual operational lead times by reconciling batch reporting intervals with real-time workflow tracking.
Establish baseline lead time metrics for service-level agreements (SLAs) in a shared services environment, accounting for request intake variability.
Classify lead time types (order-to-ship, quote-to-cash, repair-to-return) based on process ownership and customer touchpoints to avoid metric overlap.

Module 2: Value Stream Mapping for Lead Time Analysis

Conduct a value stream walk with process owners to validate data on wait times, identifying hidden delays not captured in system logs.
Calculate process cycle efficiency (PCE) by comparing total value-added time to overall lead time across a multi-step approval workflow.
Select appropriate time scales (hours vs. days) for value stream maps based on industry norms and customer tolerance for delay.
Include supplier lead time variability in extended value stream maps by incorporating inbound logistics data from procurement systems.
Use spaghetti diagrams to quantify non-value-added movement time in a warehouse layout and correlate with picking lead time.
Update value stream maps quarterly to reflect changes in staffing, equipment, or routing, ensuring lead time baselines remain accurate.

Module 3: Lead Time Reduction through Lean Techniques

Implement single-minute exchange of die (SMED) in a production line and measure impact on changeover time and downstream queue reduction.
Design and deploy a kanban system for a high-mix assembly area, setting card quantities based on lead time demand and replenishment frequency.
Redesign a batch processing step in a service operation to flow mode, adjusting staffing models to support continuous throughput.
Apply 5S to reduce search and setup time in a maintenance workshop, tracking lead time savings in work order completion.
Standardize work instructions for a repetitive task to minimize variation in processing time across shifts.
Negotiate internal service level agreements between departments to reduce handoff delays and formalize response time expectations.

Module 4: Statistical Analysis of Lead Time Variation

Construct control charts for lead time data from a procurement process to distinguish common cause from special cause variation.
Fit lead time data to non-normal distributions (e.g., lognormal) and calculate process capability indices (Ppk) for delivery performance.
Use regression analysis to identify predictors of extended lead times, such as order complexity or supplier location.
Implement moving range charts to monitor lead time stability in a software deployment pipeline.
Design and analyze a fractional factorial experiment to isolate factors affecting lead time in a call center resolution process.
Validate measurement system accuracy for lead time tracking by conducting a time study Gage R&R across multiple observers.

Module 5: Lead Time in Project Management and Product Development

Apply critical path method (CPM) to a product launch timeline, identifying tasks with the highest lead time sensitivity.
Integrate lead time buffers in agile sprint planning based on historical velocity and defect rework cycles.
Use phase-gate reviews to enforce lead time accountability by requiring evidence of time-to-decision metrics at each gate.
Map design-to-release lead time across engineering, testing, and regulatory functions, identifying approval bottlenecks.
Implement fast-tracking or crashing techniques on high-impact path items, evaluating cost and risk trade-offs.
Track engineering change order (ECO) lead time from request to implementation, linking delays to configuration management practices.

Module 6: Supply Chain and Inventory Implications of Lead Time

Adjust safety stock levels in an MRP system based on updated supplier lead time variability and service level targets.
Negotiate consignment inventory agreements with suppliers exhibiting long and unstable lead times.
Model the impact of lead time reduction on inventory turnover and working capital in a financial forecast model.
Implement vendor-managed inventory (VMI) for critical components with long procurement lead times and high demand volatility.
Evaluate dual-sourcing strategies to mitigate risk from single suppliers with extended lead times.
Align reorder point calculations with actual lead time percentiles rather than averages to prevent stockouts.

Module 7: Organizational Alignment and Performance Management

Align departmental KPIs with end-to-end lead time reduction goals to prevent local optimization behaviors.
Design cross-functional improvement teams with members from procurement, production, and logistics to address systemic delays.
Incorporate lead time reduction targets into executive scorecards with quarterly progress reviews.
Implement visual management boards at process handoff points to display real-time lead time performance.
Conduct root cause analysis on lead time excursions using structured methods like 5 Whys or fishbone diagrams.
Standardize lead time reporting formats across business units to enable benchmarking and best practice sharing.

Module 8: Sustaining Improvements and Scaling Initiatives

Embed lead time tracking into standard operating procedures (SOPs) to ensure ongoing measurement after project closure.
Conduct monthly process audits to verify that Lean improvements (e.g., kanban, SMED) are being followed as designed.
Develop playbooks for replicating lead time reduction methods across similar processes in different facilities.
Train internal coaches to lead value stream mapping workshops, ensuring consistent methodology application.
Integrate lead time metrics into enterprise dashboards with automated data feeds from operational systems.
Establish a continuous improvement backlog prioritized by lead time impact and customer value.
