Shipulski On Design

Archive for the ‘DFMA’ Category

John Teresco of Industry Week wrote a thought-provoking article on assigning responsibility of product cost to the design engineering community (and not to the manufacturing community).

An expert from his article:

“We in the United States have mistakenly allocated the responsibility for [production] cost to the manufacturing folks. We forget that the cost has already been designed into the product.”

That’s Mike Shipulski, director of engineering with plasma cutting technology provider Hypertherm Inc., reflecting on one of the lessons learned from implementing Design for Manufacturing and Assembly (DFMA) software. The accomplishments include a 600% increase in profit per square foot of factory floor space within a five-year redesign program.  Correspondingly, warranty cost per unit declined more than 75% during the same period, from January 2003 to January 2008.

Five-year implementation of DFMA software by Hypertherm creates higher profits and strong business model for improving U.S. global competitiveness

WAKEFIELD, R.I., and HANOVER, N.H.,USA, June 2, 2008—Hypertherm, the world leader in plasma metal cutting technology, has achieved a 600 percent increase in profit per square foot of factory floor space using Boothroyd Dewhurst, Inc., Design for Manufacture and Assembly (DFMA®) software within a five-year redesign program. Correspondingly, warranty cost per unit has declined more than 75 percent during that same period, from January 2003 to January 2008.

What is a DFMA Culture?  (.pdf, 1 page)

John Gilligan of Boothroyd Dewhurst, Inc. asked me to describe a DFMA culture.   Here is my description:

At the highest level, a strong DFMA culture is founded on the understanding that The Product strongly governs most everything in a company. Product function governs what customers will pay for; product structure governs a company’s organizational structure; and product features, attributes and materials govern cost. Stepping down one level, the DFMA culture is founded on the understanding that product function and product cost are coupled – they are two sides of the same coin – and are considered together when doing DFMA.

Design2Part Magazine published a good article on DFMA’s ability to cut costs, labor, floor space and improve global competitiveness.

Five-year implementation of DFMA software creates strong business model for improving global competitiveness

“We started with a vision to make radical improvements in both product performance and product economies,” stated Mike Shipulski, Hypertherm’s director of engineering. “Hypertherm met both of these goals by aggressively applying Boothroyd Dewhurst’s software within our existing programs for robust design and lean manufacturing. We found their product simplification software made it easy for us to improve a product’s performance-to-cost ratio. Moreover, we learned that DFMA ideas and financial estimates also lead to profound savings beyond labor and part cost, creating a domino effect ‘downstream’ in operational areas of our organization.”
