"Measurement Verification using Minitab"
Six Sigma Measurement System-Minitab Measurement System • Measurement System must be adequate for task at hand: data integrity • Measurement Systems contain variation – Need to Qualify and Assess • Common Tool to validate System is to use a Gage Repeatability and Reproducibility (Gage R&R) Study. Minitab Screen Measurement System • Method: – Several operators measure several parts several times • Three operators, five parts, each operator measures same part twice. – Repeatability is the variation when same operator measures the same part several times with same device. – Reproducibility is the variation when several different operators measure the same part with the same device.
