Quality Management Using Six Sigma Over the last thirty years, the views on quality management shifting from a focus on product inspection and problem identification to the theme that product quality is determined by the process used to produce the product (Jayaraman, Kannabiran, & Kumar, 2013; Kerzner, 2013). As a result many quality/process improvement initiatives and methodologies have been developed over the last few decades; one such methodology is known as Six Sigma and has become the most popular of the quality improvement initiatives (Ismyrlis & Moschidis, 2013). This paper will provide a brief overview of Six Sigma along with an explanation of the DMAIC methodology. The paper will present an example from the author’s workplace in software engineering to illustrate effective application of the DMAIC process. Six Sigma Overview As explained by Kumar and Kaushish (2015), Six Sigma is a “disciplined data-driven approach and methodology for eliminating defects in any process” (p. 7). Six Sigma stresses the reduction of variation within processes by identifying and eliminating the root causes of defects (Jayaraman et al., 2013; Kerzner, 2013; Kumar & Kaushish, 2015). The goal of Six Sigma is to get as close to zero defects as possible. The term Six Sigma comes from the Greek letter σ (sigma) which in statistics represents one standard deviation (Ismyrlis & Moschidis, 2013; Kumar & Kaushish, 2015; Mădălina, 2014). Six Sigma, or six standard deviations, yields a
