Transitioning to a Lean Culture

Jean Bye - Dotson Company 

As background, Dotson is a ductile and gray iron jobbing shop at a single 110,000 square foot location.  Active customer base is 200 and there are 137 employees.  The company pours 24 hours per day for 5-6 days per week. There are two 8000 pound induction furnaces; three 20x24 molding and pouring lines; Laempe core machines; and 40% of castings are ground on automatic Barinder grinders.

What did we have?

We were a traditional foundry with long lead times.  Nervous customers were expediting rush orders. We had very complex systems and many times conflicting priority lists.  Excess inventory and lots of excess material handling.  And, paper everywhere (which was never current).

Why did we need to change?

Like everyone else, we have lots of foreign competitive pressures.  We wanted to compete on something other than price. Many customers were putting pressure on for us to handle their inventory.  There was a severe space constraint.  Always “fighting fires” was inefficient and ineffective.  Simply stated we need flow.

How did we start?

One of our customers gave us a push and we partnered with Minnesota Technology for training.  In hindsight, this was essential.  It is almost impossible to drive a lean change without some outside help.
