The World Is Flat: A Lean Pull System Case Study

Or at least it seems that way when you need to optimize locations and layout to drive customer satisfaction.

Are you leaking money to service customers and markets?

Have you ever wondered how retail stores have what you need—regardless of how obscure it may be? A Fortune 100 company learned a valuable lesson when it switched from a distribution model to a direct-to-retail supplier.


The Problem

The company faced extended lead times that led to empty retail shelf space—and lost sales. Their customer base was loyal (the kind who would settle for a Coke even if they wanted a Pepsi), but loyalty only goes so far when the product isn’t available.

As a global manufacturer with distribution centered in the middle of the United States, they needed a better approach.


The Solution: A Global Pull System

What they did wasn’t unique or groundbreaking—but it required discipline and data mining.

The company developed a global “Pull System” based on the grocery store model. Here’s how it worked:

Demand-Driven Inventory

  • Used actual demand data and product management (not forecasts alone)
  • Created inventory levels based on demand, rounded up to the nearest packaging size
  • Positioned inventory at three levels: customer locations, distribution centers, and manufacturing plants

Triggered Replenishment

  • As inventory moved at the retail store, it triggered upstream locations to ship
  • Replenishment signals flowed based on lead time requirements
  • Classic Lean pull system—customer-focused and efficient

The Discipline Required

Sounds easy, right? That’s where discipline comes into play.

All the way through the supply chain, daily management was essential to avoid air freight or other expediting costs:

LocationRequired Discipline
ManufacturerCreate internal orders immediately when inventory drops to trigger levels—sometimes requiring overtime
Distribution CentersMove shipments in a timely manner to send proper signals to overseas manufacturers
Import & ReceivingRun like clockwork within correct timeframes
Data ManagementHandle quarter-to-quarter shipping variation and adjust accordingly

The Results

The data-driven pull system delivered across 600 U.S. retail locations:

  • 98% delivery performance at each customer location
  • Eliminated stockouts that were causing lost sales
  • 25% growth in sales from improved customer loyalty
  • More efficient process with reduced expediting costs

In the end, customers were able to buy what they wanted from a much more efficient process—resulting in improved loyalty and significant revenue growth.
