Flexible Cell Design for High-Mix, Low-Volume Manufacturing - The Lean Line Pro Deep Dive Series, #3

How do I build a production cell that still works when the product mix keeps changing?

SECOND EDITION: EXPANDED & UPDATED
This edition includes a new 25-page threaded case study showing the HM Family from analysis through launch.

If your shop runs high-mix, low-volume work, traditional lean advice often breaks down.

You do not need more theory.

You need flow that works in the real world.

Flexible Cell Design for High-Mix, Low-Volume Manufacturing shows how to design and implement one real production cell for one product family — not a theoretical layout, not a PowerPoint concept, and not a generic "lean cell" copied from a high-volume factory.

In high-mix environments, every product is different. Batch-and-queue creates chaos. "Keeping machines busy" often makes lead time worse. And a cell that works for one product may fail when the mix changes.

This book shows you how to design a cell that can flex.

Inside this book, you'll learn how to:
• Calculate takt time for a product family
• Balance operators when demand rises, falls, or shifts
• Build a routing and cycle time matrix for your family
• Design a physical cell layout that supports flow
• Set material flow paths and WIP limits
• Walk through station-by-station changeovers
• Handle volume drops, demand spikes, and rush orders
• Use production boards, andon events, and recovery logic
• Create standard work and before-and-after dashboards
• Use a complete launch checklist so you know what "done" looks like

The output is a functioning flexible cell — not a slide deck.

Who This Book Is For
This book is for high-mix, low-volume job shops, custom manufacturers, manufacturing engineers, CI leaders, operations managers, and plant leaders responsible for getting products to flow through a real production cell.

Who This Book Is NOT For
This book is not for high-volume dedicated lines, mass-production environments, or academic certification programs.

It is a focused field guide for one specific outcome: building one flexible cell for one product family.

Where This Book Fits in the Lean Line Pro System
The 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 Manufacturing
Vol. 1 — Define Product Families
↓
Vol. 2 — Reduce Setup Times
↓
Vol. 3 — Build Flexible Cells
↓
Vol. 4 — Level the Schedule
↓
Vol. 5 — Install Pull Systems

Special Situation Guides
Vol. 7 — Manage Shared Equipment
Use 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 Cell
Use this when one station inside an otherwise flowing cell must run in batches.

Written by a Practitioner
Based on 20+ years on real shop floors. No buzzwords. No academic fluff. Just practical cell design methods, examples, templates, and implementation logic you can use on the floor.

Stop managing chaos. Build one cell. Make it flow. Then do the next one.
