“Data is only as good as the system that measures it. If you can’t measure it, you can’t manage it.”
“I often say that when you measure what you are speaking about and express it in numbers, you know something about it.”
LORD KELVIN, 1891
He clearly stressed that little progress is possible in any field of investigation without the ability to measure. The progress of measurement is, in fact, the progress of science.
Measurement Systems Analysis
How good is our measurement system?
2T = 2p + 2m
2T = Total Variance
2p = Process Variance
2m = Measurement Variance
The number of distinct categories of parts that the process is currently able to distinguish (Must distinguish at least 5 types of parts)
