There’s a very interesting comparison at LeTourneau.

2 sister facilities, Longview and Houston, are similar in size, making similar products, with similar capabilities, equally strong management, both using exactly the same ERP system.

Both plants experienced tremendous growth over a 4-year period (the company grew sales from $250 MM to $1.2 B).

Look at the difference between the inventory growth needed to support that revenue growth at the 2 plants; the difference? The Longview Facility was using Demand Driven MRP as part of their TOC implementation.

NOTE: The caption for the Longview plant mentions “ASR” … until 2011, this was the name (Actively Synchronized Replenishment) given to the technology known today as Demand Driven MRP.



Question: when the explosive growth fell back, and sales even dropped … which situation would you rather be in? Houston, with high inventory and falling sales, or Longview?

Not forgetting the bottom line … the Return on Adjusted Capital Employed (RACE) indicates that Profit kept pace with growth … which as you know, is a rarity.
