Numerous attempts at installing six sigma (SS) have faced challenges and fallen short of the desired success. Thus, it becomes vital to identify the critical factors and characteristics that play a pivotal role in achieving successful adoption. In this study the research has aimed to highlight that a considerable number of corporate SS initiatives, around 60%, fail primarily due to the improper incorporation of essential elements and flawed assumptions.

To validate the influence of critical success factors (CSFs) on SS accomplishment, the study employed a research design combining exploratory and mixed-methods approaches. A Likert-scale questionnaire was utilized, and a simple random sampling method was employed to gather data. Out of the 2,325 potential participants approached, 573 responses were received, primarily from Germany, the United Kingdom and Sweden. The analysis focused on 260 completed questionnaires and statistical methods including structural equation modeling (SEM), exploratory factor analysis (EFA) and Confirmatory Factor Analysis (CFA) were utilized for data analysis.

The study acknowledged four essential components of CSFs that are imperative for sustaining the success of SS: (1) Competence of belt System employees; (2) Project management skills; (3) Organizational economic capability and (4) Leadership commitment and engagement. These factors were identified as significant contributors to the maintenance of SS’s success.

The practical implications of this research imply that institutions, practitioners, and researchers can utilize the four identified factors to foster the sustainable deployment of SS initiatives. By incorporating these factors, organizations can enhance the effectiveness and longevity of their SS practices.

The investigation's originality lies in its contribution to assessing CSFs in SS deployment within the European automobile industry, utilizing a mixed-methods research design supplemented by descriptive statistics.

In this chapter, the authors focus on the design and construction of the last MASK model, the lineage model. We learn what lineage is and how it applies to knowledge. The lineage model is differentiated from the history model. The authors explain that the history model pertains to the evolution of the environment in which knowledge develops, whereas lineage pertains to the evolution of the knowledge itself. Lineage examples are found in everyday examples such as ancestries, provenance, versions, and citation networks. A step-by-step methodology for building a lineage model is described.

This review paper aims to explore and investigate the Quality 4.0 current knowledge, emerging areas, and trends available in the literature and provide insights for future research directions. The bibliometric analysis determines the most prominent journals, authors, countries, articles, and themes. The Citation and PageRank analysis identifies the most influential and prestigious articles. The author's keyword analysis identifies the research theme, patterns, and trends within a particular area of research.

This study utilised the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) declaration as a review protocol, and the data is retrieved accordingly. Therefore, 104 articles from Scopus and 28 from Web of Science were combined in R-Environment, and 25 duplicates were removed using RStudio. Finally, 107 papers were selected for further analysis. After the abstract level screening, the study reviewed 99 articles bibliographically published in peer-reviewed journals from prominent academic databases Scopus and WoS between 2011 to April 2023. We used the VOSviewer software tool for analysing bibliometric networks that allow the construction, visualisation, and exploration of maps based on any form of network data.

The review identified emerging themes: artificial intelligence, digitalization, sustainability, root cause analysis, topic modelling, and digital voice-of-customers. To establish the intellectual structure of the field and identify gaps, co-citation and content analysis were used. The content of 49 papers in the identified clusters was then carefully analysed. The four primary themes are the relationship of Quality 4.0 with Industry 4.0, the conceptualization of Quality 4.0, recommendations for the new Quality 4.0 model, and the impact of Quality 4.0. The findings provide an excellent foundation for future research in this field for policymakers, managers, practitioners, and academia.

This is the first systematic literature review-cum-bibliometric analysis on quality 4.0 that covers the field comprehensively. Based on the present review, the paper proposes six possible future research directions to investigate.

The use of the concept of “agency,” in the sense of action that is to some extent free of “structural” constraints, has enjoyed enormous and growing popularity in the sociological literature over the past several decades. In a previous paper, we examined the range of theoretical rationales offered by sociologists for the inclusion of the notion of “agency” in sociological explanations. Having found these rationales seriously wanting, in this paper we attempt to determine empirically what role “agency” actually plays in the recent sociological literature. We examine a random sample of 147 articles in sociology journals that use the concept of “agency” with the aim of identifying the ways in which the term is used and what function the concept serves in the sociological explanations offered. We identify four principal (often overlapping) uses of “agency”: (1) purely descriptive; (2) as a synonym for “power”; (3) as a way to identify resistance to “structural” pressures; and (4) as a way to describe intelligible human actions. We find that in none of these cases the notion of “agency” adds anything of analytical or explanatory value. These different uses have one thing in common, however: they all tend to use the term “agency” in a strongly normative sense to mark the actions the authors approve of. We conclude that “agency” seems to serve the purpose of registering the authors' moral or political preferences under the guise of a seemingly analytical concept.

This article presents an exploratory analysis of perceived information needs for managing fixed public sector assets in South-Eastern Europe (SEE).

The analysis was carried out from a user needs perspective. A questionnaire was administered to government officials in SEE. Respondents were queried about what categories of information they need to make or to recommend five typical decisions concerning fixed public sector assets. Respondents also provided assessments on current availability and quality of information on fixed public sector assets, cost-benefit considerations regarding data collection and suitability of information for routine collection and updating.

The findings of this study indicate that the information collected for financial reporting purposes is recognized as insufficient to support decision-making on fixed public sector assets. However, perceived information needs by respondents are still rather basic. The need for more “sophisticated” and “strategic” information is found to be rather low, more so when the cost of collecting and processing such information is considered.

The findings of this study raise concerns about the persistently insufficient attention paid to the potential benefits that well-compiled and appropriately used asset registries could produce. The findings of this study might be useful to governments initiating the identification and measurement of their fixed assets, establishing fixed asset registries and instituting relevant regulation.

This study adds to the scant literature on the management of fixed public sector assets. It provides evidence on the perceived information needs of public sector officials, and it contributes to the ongoing debate on what good public sector asset management is and how it should be pursued.
