Assuring the quality of a measurement is crucial. In order to achieve the finest measurement and thereby the correct decision based upon it, calibration of equipment both before and after use is essential.
A cost-benefit analysis is a decision-making tool. It is a process of adding up the benefits of doing something or buying something and subtracting the costs to help us decide whether that purchase or action is worthwhile.
A friend in the industry contacted me recently for suggestions on dealing with a request from a customer of their calibration service requesting the results of vision tests on their lab people.
