Material Flow & Pull Systems: Kanban, Supermarkets, and Water Strider Routes for High-Mix, Low-Volume Manufacturing (Lean Line Pro Deep Dive Series)

How do I get materials to the right place at the right time without drowning in inventory?If material is not where it needs to be, flow does not exist.Many shops try to implement pull systems, but end up with:Kanban cards no one follows.Supermarkets that become uncontrolled storage.Material handlers constantly reacting to emergencies.Operators leaving their stations to hunt for parts.The problem is not the tools.The problem is that material flow was never designed as a system.Material Flow & Pull Systems for High-Mix Manufacturing is a practical guide to designing pull systems that actually work in high-mix, low-volume environments.This book focuses on how material moves, signals, and supports production flow — not theory, not software, and not abstract lean diagrams.Inside this book, you’ll learn how to:• Map true replenishment lead time instead of trusting quoted lead time• Design supermarkets that buffer variation without hiding problems• Size kanban systems that trigger replenishment instead of confusion• Build water strider routes that stabilize flow and reduce interruptions• Separate production problems from material handling problems• Control replenishment with clear rules, routes, signals, and ownership• Prevent pull systems from collapsing under real-world pressure• Implement pull incrementally without disrupting operationsThe goal is simple: materials arrive where they are needed, when they are needed, in the quantity needed.Who This Book Is ForThis book is for manufacturing engineers, CI leaders, operations managers, plant managers, material handlers, supervisors, and lean practitioners working in high-mix environments.If your shop struggles with material shortages, excess WIP, operators hunting for parts, or constant expediting, this book shows how to design pull systems that work in the real world.This Book Is NOT the Starting PointIf you have not defined product families yet, start with Volume 1.If changeovers still force oversized batches, start with Volume 2.If your cell layout does not support flow yet, start with Volume 3.If your schedule is still chaotic, start with Volume 4.This book assumes you have a product family, a cell, and a schedule that need material flow to support them instead of undermining them.Where This Book Fits in the Lean Line Pro SystemThe Lean Line Pro Deep Dive Series is a step-by-step implementation system for building real lean flow in high-mix, low-volume manufacturing.Each volume is designed around one bite-sized continuous improvement project — one practical system your team can understand, implement, measure, and improve before moving to the next step.If you are new to the series, start with Volume 1 and work through Volume 6 in order.The 6 Core Steps to Lean Flow in High-Mix ManufacturingVol. 1 — Define Product Families↓Vol. 2 — Reduce Setup Times↓Vol. 3 — Build Flexible Cells↓Vol. 4 — Level the Schedule↓Vol. 5 — Install Pull Systems↓Vol. 6 — Standardize the WorkSpecial Situation GuidesVol. 7 — Manage Shared EquipmentUse this when shared machines, ovens, washers, paint booths, test chambers, or other monument processes disrupt flow across multiple cells.Vol. 8 — Batch Processing Inside a CellUse this when one station inside an otherwise flowing cell must run in batches.Written by a PractitionerBased on 20+ years on real shop floors. No buzzwords. No academic fluff. Just practical pull-system methods, templates, examples, and implementation logic you can use on the floor.If material flow keeps breaking your production flow, this book shows you how to fix the system Read more
