Bill Waddell Highlights the Importance of Quick Changeovers
Recently, Bill Waddell published a great blog post highlighting the benefits of reducing changeover time. The post was about reducing the manufacturing cycle which is the time it takes to produce every product. Bill used an actual story from a client of his.
To be sure there were other inputs to the improvement – a simple demand pull method and more statistically valid methods of determining the inventory needed to cover the cycle, but set-up reduction was at the heart of it, and the improvements there translated into significantly less inventory, better on time delivery and lower costs.
Hearing stories like the one Bill wrote about just reaffirms the importance of reducing changeover time. It is something that companies take for granted. Most companies don’t see it as critical to achieving the business needs and goals.
Bill gives two great examples of where changeovers have been deemed to critical or their business would die.
I recently saw a cruise ship go through the change-over process and it is really quite similar. Dock and disembark some 3,000 passengers and their luggage and take on 3,000 new ones, restock tons of food and supplies, perform necessary maintenance to the ship, then sail again all in the course of a few hours. They have all sorts of specially designed devices and a very well trained crew of folks to do it … but they have to. That turnaround is the key to their success. In that regard they are a lot like the NASCAR or Indy cars – change-over fast or die.
Manufacturing companies don’t take this view. My question is “Why not?”
If results like the company Bill talks about receives such incredible benefit that help them stay viable and profitable, why aren’t more companies doing it? What other evidence is needed?
Does your company consider quick changeover critical to it’s success?
