Lastest Discussion of 8th Waste

Posted by Construction 25 August, 2008 (0) Comment

Over at NWLean there’s been quite a riff on the 8th waste. Eventually, the contributors concluded that recreating knowledge is the one true 8th waste. While it’s hard to argue with any of the writers’ arguments, getting at the roots of that waste is where we can begin to take effective action.

Waste in production, services, healthcare and construction are pervasive and seemingly intractable. Ohno and others noticed that. We’ve also noticed that the opportunity for waste reduction is right in front of us. All we have to do is tap the ingenuity of the workforce. The key question for me is, “What gets in the way of doing so?” It was that question that led Greg Howell and I to observe participants in the construction process.

2003 1,131 3,912
