[AT] OT Lean

[Dennis Johnson]

James,

Generally designed by the company building them.most of them had averaged around 2000 man hours per unit for assembly, paint, startup and testing. Part fabrication was subcontracted. Examples are Frac pumps, cement units, blending units, etc.
I have been part and lead of teams for cost reduction at various times. The biggest impact was generally design changes to reduce part cost, and sometimes make assembly easier.

With smaller volumes like 3 or 4 units per year it mainly caused management frustration.  Toyota uses this for their auto production, but probably not for their race car program.
