Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes.

To minimize variability, the same person assessed disease activity during the trial whenever possible.

RNP systems provide a means to minimise variability and assure reliable, repeatable and predictable flight operations.

Optical density in all wells was measured by an enzyme-linked immunosorbent assay reader to minimise variability in interpretation and to eliminate errors in transcribing results.

We tried to minimize variability by having a written reference of definitions based on the original articles of the various scoring systems and having one person coordinate the process of data collection.

Similar approaches have been shown to minimize variability [ 30, 31].

Each subject stayed at the University of Rochester General Clinical Research Center the night before the biopsy to minimize variability between subjects in the amount of activity performed on the day of the biopsy.

Strict standards would minimize technical variability, human error and difficulties in working with specimens obtained under less than ideal conditions, it said.

To minimize variability in data collection, one physician (Y.A.) coordinated the overall process.

Amplifications for all samples were performed at the same time and run on the same gel to minimize variability.
