Six Sigma: How to assure a valid measurement

In measuring it is all about the quality of the data, good data is a result of a good measuring technique. So before you measure, let’s validate the method of measurement.

Your technique to measure should be:

• Precise - A precise technique does not deviate in the result of what is being measured. The way you measure and what you measure should be the same item.
• Repeatable – A repeatable technique let’s you measure the same object multiple times and get the same result.
• Reproducible - A reproducible technique can be repeated and the same outcomes are achieved.
• Stable - A stable technique is steady and constant and does not change over time. If repeated in the future, the reading would remain the same.
