Repeatability and Reproducibility are two parts of the same coin. Each has its significance and importance. Once we understand the key difference between them both, the understanding about both enhances our interpretation of the implication of the measurement system and its related error.
As per MSA (Measurement System Analysis) 4th Edition (Core Tool as per AIAG)
Repeatability: Variations in the measurements obtained with one measuring instrument when used several times by an appraiser while measuring the identical characteristic on the same part.
Reproducibility: Variation in the average of the measurements made by different appraisers using the same gauge when measuring a characteristic on a part.
