Quality Engineering vol. 22 issue 1 - January 2010
Abstract: [This abstract is based on the authors' abstract.] In quality improvement projects, the reliability of measurements must be assessed before doing any analysis. This is particularly important in the measurement phase of a Six Sigma project. The precision of a measurement procedure can be determined by a gage R&R study, as is illustrated in the assessment of the precision of an ear temperature thermometer used in a healthcare setting. The article begins with a discussion of the principles of measurement system analysis, followed by the hospital example.
