Abstract

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.

Abstract

Purpose

The introduction of digitalisation in the shipping industry has fundamentally transformed traditional business models. This necessitates an investigation of its impact on customer satisfaction. This study aims to adapt the technology acceptance model in its survey instrument design to understand and evaluate customer satisfaction of shipping lines’ digital platforms.

Design/methodology/approach

This study used a mixed-methods approach, incorporating quantitative and qualitative research techniques. Primary data were collected through an online survey designed to measure customer satisfaction in relation to the digitalisation initiatives implemented by the shipping lines. Survey respondents comprised professionals who were online platform users, particularly in the instant spot quotation process and blockchain bill of lading.

Findings

The results for both instant spot quotation process and blockchain bill of lading revealed digital trust to be the most influential determinant of customer satisfaction, followed by perceived ease of use and perceived usefulness. There was also a very strong correlation between perceived ease of use and perceived usefulness as well as between digital trust and perceived ease of use. The managerial implications of digitalisation are also discussed.

Originality/value

The adoption of digital tools is gaining traction in the container shipping sector, and there exists a need to investigate the correlation between digitalisation and customer satisfaction. This study offers significant insights to stakeholders in the shipping industry, particularly in designing and implementing user-friendly digital platforms.

Abstract

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.

Abstract

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.

Abstract

Purpose

Outsourcing logistical activities have become a widely used approach for firms to avoid high fixed costs and heavy investment requirements and to achieve competitive advantages. Lean six sigma (LSS) has been accepted globally across sectors as a management strategy for achieving process excellence. The purpose of this paper is to feature the application of LSS for improving the supplier selection process (SSP) of outsourced logistics services in a multinational health-care company.

Design/methodology/approach

This study is based on an action research case study conducted on the SSP of the freight and distribution department in a multinational health-care company. This paper reports on the application of the LSS define-measure-analyze-improve-control (DMAIC) approach for reducing supplier selection lead time.

Findings

The study features a real-world case study of the LSS DMAIC application to improve the supplier selection process of a large health-care company. The key issues that were identified are lack of information visibility, top-down changes and unclear communication lines. To counteract these three root causes, the lean six sigma techniques that are implemented are the 5S, stakeholder analysis and standard operating procedure.

Research limitations/implications

This research provided empirical evidence of how practical challenges in SSP can be managed with the use of LSS. It further proposed plausible solutions for reducing and sustaining improved outcomes. As the study is limited to one case, the validity of the results can be improved by including more organisations and more case studies from other similar organisations.

Originality/value

Research in supplier selection processes rarely links continuous improvement ideology such as LSS to support strategic selection and procurement of logistics services. This paper could serve as a resource for both practitioners to derive useful implications and to academicians as it contributes to the LSS body of knowledge for further theory testing.
