“A lot of big companies are developing their own software engineering variance of Six Sigma training,” said Siviy, “putting software-specific examples into the normal Six Sigma curriculum.” However, she said, it’s early in the adoption curve. “In the software world there is a real lack of case studies that show applications of Six Sigma in software engineering,” she said. And those that use Six Sigma in software are often reluctant to share examples because they consider it a competitive advantage.

Still, Siviy said, “At a lot of software conferences now you see a sprinkling of presentations that somehow touch on Six Sigma or Lean, and the quality and depth of questions have evolved tremendously. In general, and not just in Six Sigma, as the [software] industry matures you see a wave of interest in measurement and analytical techniques.”

McKesson is a prime example. “Measurement is key,” Childers said. “What you can’t or don’t measure, you don’t know.”
