Using Lean Thinking in Training: A Story with Real Case Study Illustrations
As a SAFe Program Consultant (SPC) and instructor for POPM and Leading SAFe courses, I often draw upon the principles from “Lean Thinking” by James P. Womack and Daniel T. Jones to illustrate the practical application of Lean principles. Here’s a story of how I find these concepts useful, supported by real-world case studies.
Value: Understanding Customer Needs
Case Study: Wiremold
During a training session, I shared the story of Wiremold, a company that redefined value by engaging directly with customers. Wiremold’s product development team entered into a dialogue with major contractors to understand what truly mattered to them. They discovered that customers valued aesthetics and quick installation over just ruggedness and cost per foot. By focusing on these customer needs, Wiremold increased sales by 40% and improved margins significantly[1].
Application in SAFe: In SAFe, defining value from the customer’s perspective is crucial. This aligns with the principle of “Take an economic view” and helps Product Owners and Managers prioritize features that deliver the most value.
Value Stream: Identifying and Optimizing Processes
Case Study: Tesco
Tesco, a leading UK grocery chain, mapped out its value stream for cola production and discovered significant waste. By analyzing every step from raw materials to the store shelf, Tesco reduced stock-outs and halved its inventory, improving efficiency and customer satisfaction[1].
Application in SAFe: Value Stream Mapping is integral to SAFe, helping teams visualize and optimize the flow of value. This technique is especially useful during PI Planning and for managing ARTs.
Flow: Ensuring Smooth Operations
Case Study: Lantech
Lantech, a manufacturer of stretch-wrapping machines, transformed its production process by adopting flow principles. They restructured their production lines to create a continuous flow, reducing lead times and increasing productivity[3].
Application in SAFe: Creating a continuous flow of value is emphasized in SAFe through practices like Kanban and the CI/CD pipeline. This ensures that work progresses smoothly and efficiently.
Pull: Producing Based on Demand
Case Study: Toyota Service Parts
Toyota’s parts distribution system transitioned from large inventories to a pull system, where parts were produced and delivered based on actual demand. This reduced waste and improved responsiveness to customer needs[2].
Application in SAFe: The pull system is reflected in SAFe’s emphasis on producing only what is needed through practices like Just-in-Time (JIT) and Kanban, ensuring that teams work on the highest priority items.
Perfection: Continuous Improvement
Case Study: Medtronic
Medtronic’s Neuromodulation business unit used the Plan-Do-Check-Act (PDCA) cycle to guide both strategic and tactical improvements. This approach led to significant enhancements in supplier performance and overall operational efficiency[2].
Application in SAFe: Continuous improvement is a core aspect of SAFe, embodied in the principle of relentless improvement. Teams are encouraged to regularly reflect and improve their processes through Inspect and Adapt workshops.
Conclusion
By sharing these real-world examples, I help students of POPM and Leading SAFe certification courses understand how Lean principles can be practically applied to achieve significant improvements. These case studies not only illustrate the effectiveness of Lean Thinking but also reinforce the importance of adopting a Lean-Agile mindset within the SAFe framework.
