Many nations have committed to achieving carbon neutrality to combat climate change, but little is known about its drivers at the micro level and implications for firm performance and supply chain management. To address the knowledge gap, this research conducts case studies of seven early movers in the initiative by exploring the key drivers, influential stakeholders and effects of institutional pressures. We find four major drivers: 'customer enforcement', 'sustainable business value', 'environmental legitimacy' and 'competitive pressures'. Customers and competitors were the most influential external stakeholders. Shareholders and top management with intrinsic environmental values, being internal stakeholders, played pivotal roles in a proactive move to carbon neutrality when there was limited regulatory pressure.The early movers believed in the long-term economic benefits of transitioning to carbon neutrality. We also identify the implications of carbon neutrality initiatives for supply chain management. Based on the research findings, we develop a decision support framework to guide firms in transitioning towards carbon neutrality in a multi-tier supply chain context.

Purpose Lean is considered as a major management approach for improving operational productivity and organizational performance. It is a systemic philosophy that emphasizes on fulfilling customer needs, waste minimization, and a commitment to a culture of continual improvement. In recent years, many higher education institutions (HEIs) have leveraged on the use of technology to provide flexibility in learning and just-in-time training for learners in the efforts to improve both the internal processes of course delivery and enhance the provisions of education quality. In recognizing these trends in HEIs, the purpose of this paper is to identify the key factors that facilitate the conversion of printed learning resources to e-learning resources in a HEI. Design/methodology/approach This study used a qualitative exploratory case study approach and examined a unique case of a HEI that is undergoing the transformation process from printed learning resources to digital sources to simplify the processes involved in educational service delivery and operational complexity. Data sources include semi-structured interviews with key personnel directly involved in the project of converting printed learning resources to digital sources, notes taken from informal discussions, and secondary data such as minutes of meetings, learning resource archives, and relevant literature. A retrospective perspective was adopted in the case analysis since the HEI has already completed 50 percent of the conversion phase when this study was carried out. Findings Abductive reasoning approach and well-established lean principles were used to make sense of the digital transformation process of the HEI. Based on the retrospective case analysis, the authors found evidence that characterizes lean management principles and identifies the critical factors (CFs) that have facilitated the HEI to achieve the key milestones in the conversion journey. These include common vision, top management support and leadership, timely information sharing, and relationship management with key stakeholders in the transformation processes. Research limitations/implications Since this research is an exploratory case study, the results obtained cannot be generalized. Future research can be conducted to provide an impact analysis of the potential risk factors of a system that employs only the use of e-study materials. In addition, future studies can also assess the quality of the learning services that is supported by the e-resources by gathering student feedback on their e-learning experience that is supported by the online digital learning resources and learning management system. Practical implications This study provides managerial insights into the levers to engender the transformation from a traditional print learning resources model to leaning with digital e-learning resources. The insights into the CFs aid education managers to introduce process innovations and encourage behavioral changes that will benefit learners, instructors, and administers. Originality/value The study is one of the first to apply lean management principles in making sense of the transformation processes involved in the use of digital innovation in higher education context. The findings provide a holistic view of the process transformations.

Purpose The purpose of this paper is to highlight the lessons learned from two kaizen events for productivity improvement in a printing company. The paper suggests how to organize lean tools to improve productivity through the use of organized kaizen events in the printing industry to meet defined targets. Design/methodology/approach This paper is based on a field study involving participant observations. The relationships among the three specific tools, line balancing, standardized work and standardized layout that are used in a kaizen event of a printing factory, are examined. Findings Application of a mix of lean tools resulted in significant productivity improvements of 10-30 percent in the assembly area of the printing company. Based on the outcomes of the lean tools that are applied in various work areas, the best combinations of lean tools are identified and several key considerations are discussed. Practical implications This paper shows that a combined set of lean tools such as line balancing, standardized work and standardized layout can be applied to improve productivity in the printing operations, which is identifiable with a mix of processes that are both labor intensive and equipment flexible. Originality/value The paper fills the literature gap on the use of specific lean tools: line balancing, standardized work and standardized layout in the printing industry. The findings from this research can be applied to other assembly systems that are similar to the printing industry.

Purpose With the advent of technological connectivity and access to massive data, the possibilities of augmenting Lean Six Sigma’s Define-Measure-Analyze-Improve-Control (LSS’s DMAIC) problem-solving approach with advanced technologies are enormous. This paper aims to examine digital transformations (DT) of supply chains from a process improvement angle using the LSS DMAIC approach. Design/methodology/approach This paper uses a case study approach. Three exemplary case studies were examined to shed light on how LSS can aid in DT to achieve enterprise-wide improvements and enhance value across the supply chains. Findings The paper provides a conceptual framework based on a structured DMAIC problem-solving approach to drive improvements in supply chains. The conceptual framework also provides a systematic approach for big data to be integrated in LSS initiatives to achieve greater supply chain performance. Originality/value This paper extends research in LSS supply chains by providing a guidance through a conceptual framework that integrate DT and LSS supply chains to support successful digital transformation and LSS supply chains.

The outcomes of lean projects have been mixed, with some being successful while many others have not. An explanation for this is a paradox that can develop depending on the focus of the project. Ironically, in projects where the focus is on maximizing the efficiency of a resource ("resource efficiency"), this focus might lead to worsening of the resource"s efficiency, thereby generating an "efficiency paradox". This paradox does not usually arise in projects where the focus is on the subject of interest being processed through the system in the most efficient manner ("flow efficiency"). The aim of this paper is to investigate the factors that give rise to either form of efficiency. We conducted a detailed study of eight lean projects in two large hospitals. In doing so, we advance the theory of lean service operations by identifying four key contextual factors that drive the orientation of a project to resource or flow efficiency. These are: service variety, interdependency, capital resource intensity, and service uniqueness. We propose a conceptual framework and four propositions that integrate the contextual factors to determine the dominant focus in lean projects. Through this, recommendations are made as to how the efficiency paradox can be avoided.
