TL;DR: This study proposes a novel integrated methodology to formulate and solve the Lean Six Sigma project portfolio as a 0–1 Bi-objective Quadratic Programming Problem and permits tackling the problem as a Mixed-Integer Quadratically-Constrained Programming Problem.

TL;DR: The results show that the company successfully applied the Lean Six Sigma methodology and saved a considerable sum of money by reducing overfilling of final product (ginger bread) and the proposed framework integrates lean tools and Six Sigma Define, Measure, Analyze, Improve, and Control methodology to reduce overfill and rework to enhance the bottom-line results.
Abstract: Lean manufacturing has been acknowledged as a methodology to eliminate waste, while Six Sigma has been regarded as a diagnostic tool to improve processes by eliminating variation. The important objective of both of the methodologies is to identify the most critical processes to generate savings for an organization. Lean Six Sigma integrates these two approaches into an effective hybrid method, which combines the variability elimination tools from Six Sigma with the waste elimination practices from lean manufacturing. This paper aims to study the application of Lean Six Sigma in a medium-sized confectionary. The results show that the company successfully applied the Lean Six Sigma methodology and saved a considerable sum of money by reducing overfilling of final product (ginger bread). This study proposes a Lean Six Sigma framework to reduce overfill and rework. The proposed framework integrates lean tools and Six Sigma Define, Measure, Analyze, Improve, and Control methodology to reduce overfill and rework to enhance the bottom-line results. The result of this study will help food small- and medium-sized enterprises to effectively apply Lean Six Sigma to reduce variability and consequent waste in their production process.

TL;DR: The paper conceptually proposes Green Lean Six Sigma and proposes Six Sigma, and specially its problem solving methodology DMAIC, as an approach that may help in overcoming the limitations of green lean.
Abstract: Historically, profitability and efficiency objectives have been the prevailing interest for organisations. However, the move towards green operations has forced companies to seek alternatives to combine these with green objectives and initiatives. Green lean is the result of this combination. The purpose of this paper is to critically discuss the green lean approach and the potential benefits of integrating Six Sigma to enhance its effectiveness. The paper is based on a literature review that discusses the synergies and differences of lean and green, and its main limitations. Departing from the limitations identified, the paper then proposes Six Sigma, and specially its problem solving methodology DMAIC, as an approach that may help in overcoming the limitations of green lean. Thus, the paper conceptually proposes Green Lean Six Sigma. It intends to offer academics, researchers and practitioners interested in lean and green with some initial conceptual ideas regarding their possible integration with Six Sigma.

TL;DR: In this paper, the impact of Lean Six Sigma and a firm's quality management capabilities in developing its organizational learning capability (OLC), especially in the business process outsourcing (BPO) environment of a developing country, is analyzed.
Abstract: Purpose – This paper analyses the impact of Lean Six Sigma and a firm's quality management capabilities in developing its organisational learning capability (OLC), especially in the business process outsourcing (BPO) environment of a developing country.Design/methodology/approach – Using a multiple case study incorporating embedded design, findings from four Indian BPO firms are analysed.Findings – Findings confirm the critical and relatively unexplored role that firms' Lean Six Sigma and quality management capabilities play in developing OLCs.Research limitations/implications – Owing to its qualitative case study design, findings from this study are not able to be generalised to the wider population, instead, the findings are generalised to relevant theory for future development.Originality/value – The above relationship is examined in a novel research setting and the study also looks at which elements of Six Sigma and TQM content, if not well developed, hinder the development of OLCs.
