Lean Six Sigma Procurement Process Improvement Training Course

Course overview

Procurement teams are expected to shorten requisition-to-purchase-order cycle times, reduce maverick spend, improve supplier performance, and maintain audit-ready controls at the same time. Yet many procurement processes contain hidden queues, duplicate approvals, incomplete specifications, unclear hand-offs, and supplier-data defects that create rework and delay. This course equips participants to diagnose those problems with evidence rather than assumption, focusing Lean Six Sigma improvement effort on the procurement steps that affect cost, service, compliance, and stakeholder confidence.

Participants learn to apply the DMAIC framework to source-to-contract, procure-to-pay, supplier onboarding, contract administration, and supplier performance processes. They map current-state workflows using SIPOC and value stream mapping, define critical-to-quality requirements, collect procurement process data, calculate baseline performance, identify root causes with Pareto analysis and fishbone diagrams, and test improvement ideas. The course also covers control plans, standard work, error-proofing, dashboard measures, and the practical use of Excel, Minitab, and Power BI for procurement analysis.

Instruction combines focused teaching with a running procurement case involving delayed purchase orders, non-compliant buying, invoice exceptions, and supplier onboarding delays. Participants work in teams to build a DMAIC project charter, process map, data-collection plan, root-cause analysis, future-state workflow, and control plan. Each participant leaves with a completed Lean Six Sigma procurement improvement project pack that can be adapted to a live process challenge within their organisation.

The course is suited to procurement and supply chain professionals who need a disciplined method for improving transactional efficiency, supplier-facing processes, and governance controls. It is particularly valuable where procurement performance discussions need to move from anecdotal complaints to measurable operational evidence.

Course objectives

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

• Define a procurement DMAIC project charter with problem statement, scope, baseline, benefits, risks, and stakeholders
• Map requisition-to-order and procure-to-pay workflows using SIPOC, swimlane mapping, and value stream mapping
• Translate stakeholder needs into critical-to-quality requirements and operational procurement measures
• Design a procurement data-collection plan for cycle time, touch time, first-pass yield, compliance, and exception rates
• Analyse procurement process variation using Pareto charts, run charts, histograms, and basic capability measures
• Identify root causes of purchasing delays and defects using fishbone diagrams, 5 Whys, and cause-and-effect matrices
• Develop future-state procurement workflows using waste removal, standard work, approval rationalisation, and error-proofing
• Create a control plan and performance dashboard specification to sustain procurement process improvements

Benefits of attending

Target competencies

Who should attend

• Procurement Managers — who need measurable methods to reduce cycle time, leakage, and process failure
• Category Managers — who must improve sourcing-to-contract hand-offs and supplier-facing execution
• Procurement Officers — who process requisitions, purchase orders, and exceptions and can identify operational waste
• Supply Chain Managers — who depend on reliable buying processes to protect material availability and service levels
• P2P Process Owners — who are accountable for requisition, approval, ordering, invoicing, and payment workflow performance
• Procurement Analysts — who need to turn ERP and supplier data into defensible improvement priorities

Requirements and prerequisites

This is a foundation-to-intermediate course and does not require prior Lean Six Sigma certification or advanced statistics. Participants should understand the basic purpose of purchasing, sourcing, purchase orders, supplier records, invoices, approvals, and contracts within their own organisation. Familiarity with spreadsheets is useful, including entering data, sorting, filtering, and creating simple charts in Microsoft Excel. Participants should be prepared to discuss a real procurement process or recurring issue from their workplace. Prior use of Minitab, Power BI, statistical software, process mapping tools, or formal DMAIC projects is not required; these are introduced during the course.

Training methodology

The five days use instructor-led demonstrations, guided analysis, team workshops, and a continuous procurement case rather than abstract manufacturing examples. Participants map a requisition-to-order process, inspect sample purchase-order and invoice-exception data in Excel and Minitab, and translate findings into improvement actions. Group work simulates discussions with requesters, approvers, finance, and suppliers, including trade-offs between speed and control. The final session is an application-planning workshop in which participants tailor a DMAIC charter, measurement approach, and 90-day action plan to a procurement process in their own organisation.

Course outline

Day 1: Define the Procurement Improvement Problem

• Lean Six Sigma principles in source-to-pay operations
• DMAIC roles, gates, and procurement project governance
• Voice of the customer and voice of the business in procurement
• Critical-to-quality requirements for buying service and compliance
• Procurement problem statements, goal statements, and scope boundaries
• SIPOC analysis for requisition-to-purchase-order workflows
• Stakeholder mapping across requesters, approvers, finance, and suppliers

Workshop: Participants develop a DMAIC project charter and SIPOC diagram for a delayed purchase-order processing case.

Day 2: Measure Procurement Process Performance

• Swimlane mapping of procure-to-pay hand-offs
• Value stream mapping for procurement queues and touch time
• Operational definitions for cycle time, first-pass yield, and compliance
• Data-collection plans for ERP, e-procurement, and invoice data
• Sampling approaches for purchase-order and supplier-onboarding records
• Baseline calculation for procurement defects and exception rates
• Excel analysis of timestamps, approvals, rework, and ageing

Workshop: Participants create a current-state value stream map and data-collection plan for the case procurement process.

Day 3: Analyse Delay, Defects, and Spend Leakage

• Pareto analysis of purchase-order delays and invoice exceptions
• Run charts and time-series patterns in procurement cycle time
• Histograms and descriptive statistics for process variation
• Process capability concepts for service-level performance
• Fishbone diagrams for procurement delay and compliance failures
• 5 Whys analysis for recurring approval and specification defects
• Cause-and-effect matrices for prioritising root causes

Workshop: Participants analyse a procurement data set and produce a ranked root-cause hypothesis supported by charts and evidence.

Day 4: Improve Source-to-Pay Flow and Controls

• The eight wastes in procurement administration
• Future-state value stream design for requisition and approval flow
• Approval rationalisation and delegated-authority design
• Standard work for requisition review and purchase-order creation
• Error-proofing incomplete requisitions and coding errors
• Supplier onboarding redesign and master-data quality controls
• Improvement prioritisation using impact-effort matrices and FMEA

Workshop: Participants design a future-state procurement workflow with prioritised countermeasures, ownership, and implementation risks.

Day 5: Control Results and Launch the Improvement Project

• Procurement control plans and process ownership
• KPI design for cycle time, compliance, quality, and supplier service
• Dashboard requirements in Microsoft Power BI
• Visual management and daily exception review routines
• Response plans for out-of-control procurement measures
• Benefits tracking for cost avoidance, productivity, and risk reduction
• 90-day DMAIC implementation planning and project tollgates

Workshop: Participants complete a procurement control plan, dashboard specification, and 90-day implementation roadmap for their chosen process.
