Based on the UW article cited by George, every job shop worth its salt has practiced "quick response manufacturing." We just didn't have the chutzpah to claim the process as unique and give it a fancy moniker all dressed up with upper case letters and everything.
The whole idea, of course, is to reduce lead time from initial inquiry to finished product on the customer's dock or in place at his facility.
Key to the process is avoiding an often asinine process of customers sending out requests for proposals or quotations and then sitting back on their collective backsides waiting for suppliers to "guess" at the urgency required.
Elsewhere (
Wes Bucey on quoting and empowerment), I talked about my own process for short-circuiting the time-consuming "auction" process so many buyers seem enamored of. We were similarly engaged with our own suppliers (our "go to" guys) so that we could eliminate delays in obtaining materials, equipment, and supplies. I charged more than shops who considered themselves our competitors, but we were worth it, delivering net value to every customer.
