ABSTRACT
Lean Six Sigma (LSS) is often referred to as a process improvement program. This chapter explains the basics of process improvement. The new LSS is a blend of many methodologies to include not only Lean and Six Sigma, but also Agile as well as basic Project Management. However, the trend is overwhelming to participate in training programs that combine both Lean and Six Sigma methodologies; this combined science is known as LSS. Both Six Sigma and LSS are problem-solving models that allow for maximum Return-on-Investment by making existing activities better, faster or more cost effective by using methodologies and tools designed for those specific purposes. Since Lean works to eliminate or reduce waste and Six Sigma works to eliminate or reduce mistakes, the methodologies are not mutually exclusive and work well together.
