Abstract
Purpose
The paper aims to review the literature on Six Sigma projects through a broad framework of Six Sigma project selection process. It proposes a process framework approach of six sigma project selection and enumerates various recent tools and methods required for each stage. The review aims to expand the domain of Six Sigma project selection by identifying the importance of project portfolio approach.
Design/methodology/approach
The study used a process framework approach and systematic literature review to identify and classify various literature pertaining six sigma projects and its associated tools and methods
Findings
The paper provides broad insights about the opportunity and direction to future research in the area of Six Sigma project. Emerging research opportunities exist in the area of Six Sigma project risk management and selecting portfolio of projects.
Research limitations/implications
The study has its own limitations because of its chosen research approach. The process framework developed for classification of literature is based on expert opinion. Further research can be carried out to validate it.
Practical implications
This study will benefit new researchers entering the field of Six Sigma to identify new research opportunities and issues for their research interest. Second, industry practitioners and consultants working in the area of Six Sigma may work towards more successful implementation of Six Sigma.
Originality/value
The paper fulfils an identified gap of review of Six Sigma project selection.

Abstract
Purpose
Since passenger safety is critical, aviation maintenance is essential. Aviation maintenance management is changing due to Industry 4.0 (I4.0). According to earlier research, I4.0 technologies improve aircraft manufacturing efficiency and responsiveness through automation, predictive maintenance and process self-optimization. Thus, this study examines I4.0 research and aircraft maintenance's potential interaction.
Design/methodology/approach
Using a text-mining methodology, this paper looks at the state of the art in aviation maintenance research in the I4.0 era. We used the topic modeling approach and Latent Dirichlet Allocation (LDA) technique to analyze the abstracts and indexed keywords of 929 research articles on the intersection of aviation maintenance and I4.0, subsequently clustering them into eight topics.
Findings
We have mapped out the emerging research trends at the intersection of “aviation maintenance” and “I4.0 technologies”, and presented suggestions for theoretical frameworks, applied frameworks and future lines of inquiry. This paper makes a theoretical contribution to the systematization of literature on I4.0 technologies in aviation maintenance. It provides valuable insight for managers by exploring the implications and opportunities that arise in light of recent innovations brought by I4.0 in aviation maintenance.
Originality/value
This study focuses on the use of Industry 4.0 technologies in aircraft maintenance processes, contributing to the growing research on digital technology in maintenance and maintenance, repair and overhaul (MRO). Furthermore, the study's analysis of the LDA topic model provides valuable insights for future research on using I4.0 technologies to investigate specific areas of application in the context of digital maintenance.

Abstract
Purpose
Previous research on last mile delivery (LMD) has not attempted to identify thematic patterns within the literature to comprehend the prevailing research direction within this field. This study thus aims to identify significant latent topics in the technology-focused and consumer-centric LMD literature over a span of 45 years (1978–2023) and to propose topics for future research in this domain.
Design/methodology/approach
This study adopted a text mining methodology in conjunction with bibliometric analysis to comprehensively review the literature.
Findings
The findings of this study reveal the top emerging topics in the field of LMD and include the bibliometric results.
Research limitations/implications
This study is based on highly rated Australian Business Deans Council journals found in Scopus and Google Scholar. In addition to its methodological novelty, this study contributes to two interconnected strands of literature. First, it offers a fresh categorization of different concepts in the LMD literature, emphasizing the use of technology built upon prior efforts in the field. Second, it demonstrates the evolution of focus on different dimensions of consumer-centric LMD over time.
Originality/value
To the best of the authors’ knowledge, this study is the first to use an unsupervised text mining method called topic modeling in the overall consumer-focused LMD literature. It thus overcomes the limitations of previous analytical methods for conducting literature reviews focused on other time periods.
