Is OEE data subject to misinterpretation?
Without a doubt! The two shift example in the Calculating OEE section is a great example. OEE tells you nothing about how much your resources actually cost in dollars, what the easiest improvement actually is, or how much it will cost you to make that improvement. What you should look for in OEE is losses and bottlenecks that can be eliminated for a cost/benefit that makes sense. OEE data is only meaningful in the context of your situation and your efforts to improve it.
