The first paper, "Lean Six Sigma for the Process Improvement of Yarn Package Dyeing in Textile Industry" by A S M Touhidul Islam, captures and highlights the practices linked to Yarn dyeing, a big area in textile industry, which has been found overlooked in the extant Lean management literature. With a decade's practical experience in four renowned knit composite apparel industries in Bangladesh, the author has identified the scope to apply Lean Six Sigma in this area. Standard time for different processes is derived with detailed practical observations with case study-driven examples, which have helped to measure the lead time of yarn dyeing using value stream mapping. This paper has implications and takeaways for professionals as the outcomes may be readily applicable to improve the capacity and efficiency of yarn dyeing in any textile industry. This study also inspires academicians to explore further opportunities to apply Lean Six Sigma across practice sectors with specific emphasis on textile industry. Different data requirements for further applications of Lean Six Sigma have also been recommended along with scope and ideas for improvement per process per function.

The second paper, "Application of Quality Management Tools in Student Retention: A Case Study from International School, Duy Tan University" by Huynh Linh Lan from Vietnam, highlights and emphasizes the importance of quality management in enhancing student retention. The author describes how suitable quality management tools not only increase retaining students until graduation, but also help them succeed at university, in the study context of Vietnam. The author details that every year, a large percentage of Vietnamese students drop out of schools due to many reasons and thus links the role of educators in creating a clear strategy for retention if they have a good understanding of their students, driven by the data available through learning management system and analytics tools. This study has utilized the quality management tools, combined with group discussion and direct interview of 300 students, to suggest some administrative implications to build the process used in learner motivation and retention.

The third paper, "Green Supply Chain Management: Drivers, Practices and Performance" by Sunita Jatav and Jaya Nema, discusses Green Supply Chain Management (GSCM), which though is in place for over a decade now, has emerged as a key approach for enterprises seeking to become environmentally sustainable. This paper aims to evaluate and describe GSCM drivers, practices and performance among various Indian manufacturing organizations. Based on a literature review, propositions are put forward. An empirical study using survey research is completed involving appropriate items using literature and industry expert inputs. Using exploratory factor analysis to derive groupings of GSCM drivers, practice and performance from the survey data, categorical and descriptive results have been presented with evaluation and comparative analysis of the research findings. Indian enterprises have increased their environmental awareness due to regulatory, competitive and marketing pressures and drivers. The authors highlight that this awareness however has not been translated into strong GSCM practice adoption, let alone into improvements in some areas of performance, where it is expected. This empirical work is one of the few and pioneering efforts to investigate GSCM practices in the Indian manufacturing sector.

These three research papers highlight the orchestrated approaches for improving quality, effectiveness and sustainability across operations management verticals, which find relevance and importance in the current context.
