Inter-industry generic Lean Six Sigma project definitions

Purpose The objective of this research is to provide practitioners with inter-industry applicable rules and guidelines for the Lean Six Sigma (LSS) project definition phase. This research resulted in 13 inter-industry generic project definitions that are divided by four performance dimensions: quality, dependability, speed and cost efficiency. Design/methodology/approach A total of 312 previously executed LSS improvement projects in a broad variety of industries at black belt or master black belt level are analyzed. All these projects have followed the LSS methodology and are characterized by the use of critical to quality (CTQ) measurements and the structured improvement method of define, measure, analyse, improve and control for operations improvement. Findings This research resulted in 13 inter-industry generic project definitions that are divided by four performance dimensions: quality, dependability, speed and cost efficiency. Three factors that have stood out in this research are; the difficulty to capture the performance dimension flexibility in LSS project definitions, the strong focus on internal organizational benefits in defining CTQs for LSS project definitions and the unclear alignment of LSS project definitions to existing strategic objectives of the company. Originality/value This research established useable generic LSS project definitions including generic CTQ’s measures, applicable to multiple industries. These generic LSS project definitions provide useful guidance in the initial LSS project phase, helping to decompose strategic focal points into clear and measurable project objectives.
