Sun Monitor Costs
Customer Profile – GEMS Engineering – 3 Sites in Milwaukee Area
Process Capability – Before
Business Problem & Impact
Standard Engineering workstations pricing continues at the
same high level yearly. Sun has moved to more standard Z bench (ST) = - 3.0
parts, allowing substitution of high cost Sun parts for less-lostly Avg. Cost = $1000
3rd party products, which can save GEMS thousands per year.
