Variability Reduction: A Statistical Engineering Approach to Engage Operations Teams in Process Improvement

Quality Engineering vol. 24 issue 2 - April 2012

Abstract: A U.S. printing company successfully implemented a teambased variability reduction methodology to enable operations teams, primarily pressmen and bindery operators, to establish standard processes, identify and eliminate sources of variability, establish the daily disciplines necessary to sustain the productivity improvements over time, and create an environment to facilitate step-change productivity improvement through Six Sigma projects. This article shares the methodology and how it addressed the hallmarks of a problem requiring statistical engineering and incorporated key aspects of the theory of statistical engineering.

Keywords: Case study; Process improvement; Process variability; Productivity; Six Sigma; Stability; Statistical engineering
