Measurement Capability

摘要

Measurements are made all the time: in processes, to see how well work is progressing and in commerce. Most of the time, we trust these measurements are adequate for the task. Being adequate means having a small enough uncertainty (enough accuracy, resolution and precision) to support whatever the measurement is being used for. Measurements are not always adequate, though. Some scientific and industrial processes can push the limits of what can be done at all. Other times, the equipment or algorithms being used are not up to the job. Often, the practitioners have simply not given enough thought, or any thought, to the measurement requirements.
