Lean Supply Chain Waste Reduction Training Course

Course overview

Supply chain waste is rarely confined to one warehouse, buyer or carrier. Excess safety stock can mask inaccurate lead times; urgent purchase orders can create premium freight; large batch sizes can increase handling, ageing and obsolescence; and poorly designed replenishment rules can leave customers waiting while inventory accumulates elsewhere. This course equips supply chain professionals to identify these connected losses using Lean methods that work across procurement, planning, warehousing, transport and supplier operations.

Participants learn to distinguish value-added work from the eight Lean wastes in end-to-end material and information flows. They build current-state and future-state value stream maps, calculate takt time, lead time, inventory days, process cycle efficiency and first-pass yield, and use root-cause tools including 5 Whys, fishbone diagrams and Pareto analysis. The course applies pull replenishment, Kanban sizing, supermarket design, standard work, visual management, heijunka and supplier collaboration to practical supply chain constraints rather than treating Lean as a factory-only discipline.

Teaching combines instructor-led demonstrations with a running supply chain case involving demand volatility, long supplier lead times, warehouse congestion and expedited transport. Teams work with operational data in Microsoft Excel, construct a value stream map, prioritise waste using an impact-effort matrix, and test countermeasures against service, inventory and cost measures. Each participant leaves with a documented Lean supply chain waste-reduction charter: a current-state diagnosis, quantified opportunity statement, future-state design, 90-day action plan, KPI baseline and stakeholder ownership plan.

The course is designed for professionals who already work with supply chain data, processes or suppliers and need a disciplined method for converting improvement observations into measurable operational results. It is equally useful for managers sponsoring cross-functional inventory, lead-time or logistics cost reduction initiatives.

Course objectives

By the end of this course, participants will be able to:

• Map an end-to-end supply chain value stream using material-flow and information-flow symbols
• Calculate lead time, process cycle efficiency, inventory days, takt time and first-pass yield from operating data
• Classify procurement, planning, warehouse and transport activities against the eight Lean wastes
• Diagnose recurring supply chain problems using Pareto analysis, 5 Whys and fishbone diagrams
• Design pull replenishment controls using Kanban sizing, supermarket locations and reorder triggers
• Create standard work and visual management controls for receiving, picking, replenishment and supplier follow-up
• Prioritise waste-reduction countermeasures with an impact-effort matrix and quantified benefit estimate
• Produce a 90-day Lean supply chain waste-reduction charter with KPIs, owners, milestones and escalation points

Benefits of attending

Target competencies

Who should attend

• Supply Chain Managers — who need to reduce lead time, inventory and operational friction across functions
• Procurement Managers — who must address supplier lead-time variation, order expediting and purchasing process waste
• Demand and Supply Planners — who need to improve replenishment rules and expose planning-driven inventory waste
• Warehouse and Distribution Managers — who are accountable for flow, handling time, picking accuracy and space utilisation
• Logistics Managers — who need to reduce premium freight, transport waiting and avoidable shipment complexity
• Continuous Improvement Specialists — who facilitate Lean projects across procurement, logistics and operations

Requirements and prerequisites

Participants should have practical exposure to at least one supply chain process, such as purchasing, demand planning, inventory control, warehousing, transport or supplier management. They should be comfortable reading basic operational measures including order quantities, lead times, stock levels, service levels and delivery performance. Familiarity with Microsoft Excel formulas, tables and charts is helpful because exercises use operational datasets, but advanced analytics or programming is not required. Prior Lean certification is not required; the course introduces the Lean tools used. Participants do not need access to an ERP system during the course.

Training methodology

The instructor uses short Lean method briefings followed by supply chain-specific data analysis, mapping and design exercises. Participants work in teams on a multi-echelon case covering supplier ordering, inbound receiving, warehouse replenishment and customer dispatch. They calculate baseline measures in Microsoft Excel, draw current- and future-state value stream maps, challenge assumptions through structured root-cause analysis, and test pull-system decisions. Daily debriefs connect each tool to participants' own operations. The final session is a facilitated application-planning workshop built around an actual workplace waste problem.

Course outline

Day 1: Lean thinking for end-to-end supply chain flow

• Customer value and value-added definitions in supply chain operations
• The eight Lean wastes applied to procurement, planning, warehousing and transport
• Material flow versus information flow across the supply chain
• Lead time, touch time, queue time and process cycle efficiency
• Demand patterns, takt time and service-level implications
• Supply chain waste walk observation techniques
• Baseline KPI selection for cost, flow, quality and delivery

Workshop: Teams conduct a waste walk through a simulated order-to-delivery process and produce a waste observation log with initial KPI hypotheses.

Day 2: Value stream mapping and waste diagnosis

• Current-state value stream mapping symbols and conventions
• Mapping supplier, inbound, warehouse and customer information flows
• Inventory triangles, queue points and lead-time ladders
• Calculating inventory days and process cycle efficiency
• Pareto analysis of shortages, expedites and non-conformances
• 5 Whys and fishbone diagrams for supply chain root causes
• Constraint identification and bottleneck analysis

Workshop: Participants create a current-state value stream map for the case supply chain and quantify its principal delay, inventory and handoff wastes.

Day 3: Pull replenishment and inventory flow control

• Push, pull and hybrid replenishment models
• Kanban sizing using demand, lead time, container quantity and safety factor
• Supermarket design and replenishment loop definition
• Reorder points, min-max controls and inventory segmentation
• Heijunka principles for demand and workload levelling
• Batch-size reduction and lot-sizing trade-offs
• Supplier scheduling and collaborative replenishment signals

Workshop: Teams design a pull replenishment loop for selected case items and produce a Kanban calculation, supermarket layout and replenishment rule.

Day 4: Stabilising execution through Lean controls

• Standard work for purchasing, receiving, picking and replenishment
• Visual management for inventory status, shortages and exception queues
• First-pass yield and error-proofing in supply chain transactions
• Daily management boards and tiered escalation routines
• Supplier performance scorecards and corrective-action triggers
• Kaizen event planning for warehouse and logistics processes
• Change management for cross-functional Lean countermeasures

Workshop: Participants build a standard-work sheet and visual daily management board for a case process with recurring receiving and picking failures.

Day 5: Future-state design and implementation planning

• Future-state value stream mapping and flow design
• Quantifying savings from inventory, lead-time and premium-freight reduction
• Impact-effort prioritisation of Lean countermeasures
• A3 problem-solving structure for supply chain improvement
• KPI dashboards for service, inventory, quality and flow
• 90-day implementation roadmap and governance cadence
• Stakeholder mapping and risk controls for Lean deployment

Workshop: Each participant completes and presents a Lean supply chain waste-reduction charter containing a future-state map, KPI baseline, countermeasures, owners and 90-day plan.
