RE: The real definition
I believe that the definition I proposed does indeed address worker safety and
input materials. Workers are the first to be exposed to any form of waste (I
call them process losses). By reducing loss, you reduce the amount of material
used. Cause and effect diagrams address material changes along with technology
change, method change and worker activities changes. Products will be addressed
when there is take back legislation and the materials become a waste then they
are returned. I think the use of the word waste is sometimes a problem. The
real beauty of the Japanese definition of just-in-time is that it addresses all
seven forms of waste in the Toyota manufacturing system. As pollution
prevention practitioners we are only dealing with the physical form of waste.
The problem is much bigger. We need to integrate our work into this larger
picture instead of isolating ourselves behing the myriad of terms that we have
invented to make our work sound important.
