Factors Affecting Measurement Systems
Factors might include:
- Equipment: measuring instrument, calibration, fixturing, etc.
- People: operators, training, education, skill, care
- Process: test method, specification
- Samples: materials, items to be tested (sometimes called "parts"), sampling plan, sample preparation, etc.
- Environment: temperature, humidity, conditioning, pre-conditioning,
- Management: training programs, metrology system, support of people, support of quality management system, etc.
These can be plotted in a "fishbone" Ishikawa diagram to help identify potential sources of measurement variation.

Famous quotes containing the words factors, affecting, measurement and/or systems:
“Language makes it possible for a child to incorporate his parents’ verbal prohibitions, to make them part of himself....We don’t speak of a conscience yet in the child who is just acquiring language, but we can see very clearly how language plays an indispensable role in the formation of conscience. In fact, the moral achievement of man, the whole complex of factors that go into the organization of conscience is very largely based upon language.”
—Selma H. Fraiberg (20th century)
“It is a relief to read some true book, wherein all are equally dead,—equally alive. I think the best parts of Shakespeare would only be enhanced by the most thrilling and affecting events. I have found it so. And so much the more, as they are not intended for consolation.”
—Henry David Thoreau (1817–1862)
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
