Certainty in measurement

The reading has to be right

The reading should be accurate enough for the decision it drives.

Certainty in supply

Your schedule has to hold

Lead times, alternates, and stocked parts matter when a production date cannot slip.

Certainty in quality

The next lot should match the last

You need parts that perform consistently, lot after lot.
