I was talking to Greg Knight of AMT Machine Systems (ServoCam), whose company adapts old school cam Brown & Sharpes into 21st century CNC hybrids. He was lamenting the difficulty he has selling his product to job shop owners who have no visibility of work from one month to the next. The days of consistent long-running contracts seem to have vanished like untaxed cigarettes.
In the used machinery business, and I’m guessing also in the new machinery business, we live with future blindness. Projections are difficult, which drives accountants and bankers mad, but they probably deserve it. Business people crave the myth of being in control. They think they deserve an accurate vision of the future. And now we must live with the blank order sheet and wait for the sketchy buyers to call or email their requests for parts in a week. “Sure,” you say obediently, and immediately order material for next day delivery. Welcome to the new normal.
Every time I proclaim that I do not pray at the “Temple of Lean” I am chastised as a manufacturing heretic. But in a sloppy, erratic, fog shrouded world, “lean” is a dream lived fully only in the predictable world of government contracts, lubricated by friendly politicians from “safe districts,” a rarity in our blindfolded world.
Question: Is lean manufacturing impractical for most job shops in today’s economy?
