Lean Six Sigma for Sustainable Business Practices: A Case Study and Standardisation

International Journal for Quality Research

Lean Six Sigma (LSS) modifies the DMAIC approach by emphasizing speed. Lean focuses on streamlining a process by identifying and removing non-value added steps. A leaned production process eliminates waste. The target metrics, which affect any business include zero wait time, zero inventory, scheduling using customer pull, cutting batch sizes to improve flow, line balancing, and reducing overall process time. Lean Six Sigma's goal is to produce quality products that meet customer requirements as efficiently and effectively as possible. In this article, we present various Lean performance characteristics that can be effectively used for improving a sustainable business process through a case study.
