This paper aims to unearth the essential components of Six Sigma for successful deployment and sustainment of service quality in four different organizations in the United Arab Emirates (UAE). More specifically, the paper is intended to determine the motivation to apply Six Sigma, Voice of Customer, Key Performance Indicators (KPIs), Critical-to-Quality (CTQ), readiness factors, Critical Success Factors, sustainment measures, tools and techniques used, challenges/barriers and performance impact on the company.

An exploratory research methodology with multiple case study analyses was adopted to determine the answers to the research objectives. Four case studies from different service processes of four companies were analyzed. The case studies were collated from these companies via a case study protocol with pre-defined criteria.

The analysis shows that service operation improvement projects are primarily dependent on the voice of the internal customer, with return on investment in savings as the KPI of the process. Most organizations prefer cycle time and errors as the CTQs in the Six Sigma projects. Even novice users can effectively apply the Six Sigma methodology with external experts’ assistance, mentoring and interventions. Across the case studies, it is observed that the projects were successfully deployed due to the support of top management leadership, effective communication and cross-functional teams. Employee resistance to change is the common barrier observed during the case study analysis. Eventually, in all the four case studies, Six Sigma is executed with standard tools and techniques within the define, measure, analyze, improve, control (DMAIC) approach.

The present study’s findings cannot be generalized due to the limited number of case study analyses in different ecosystems in the UAE. The authors would like to analyse and report more case studies in service quality improvement through the Six Sigma methodology to comprehend and develop a generic roadmap for the deployment of Six Sigma in the UAE service industry.

The study’s findings provide insights into commonalities and differences between the essential factors of Six Sigma deployment and sustainability in UAE companies.

The study results might help the policymakers and key decision makers in UAE and other countries understand the effectiveness of Six Sigma in service quality improvement with its essential factors for deployment.

Institutional economics at the societal level focuses on the examination of interpersonal and impersonal economic, political and social institutions within a given polity and how such institutions might change and evolve over time. Such examination is critical to both international business scholars and practitioners if they are to successfully navigate variations in the rules of the game in international trade and commerce. Whilst institutional economics offers an immense body of literature on institutions, it offers surprisingly few theoretical or conceptual tools for empirical analysis. This chapter discusses five extant frameworks and proposes an ontological theoretical framework developed from interdisciplinary sources to underpin extant frameworks and thereby guide international business researchers in designing more effective research instruments for examining institutional change across and between cultures.

The purpose of this paper is to evaluate the experiences of tertiary students learning oral presentation skills in a range of online and blended learning contexts across diverse disciplines.

The research was designed as a “federation” of trials of diverse online oral communications assessment tasks (OOCATs). Tasks were set in ten courses offered across all five faculties at University of Newcastle, Australia. The authors collected and analysed data about students’ experiences of tasks they completed through an anonymous online survey.

Students’ engagement with the task was extremely positive but also highly varied. This diversity of student experience can inform teaching, and in doing so, can support student equity. By understanding what students think hinders or facilitates their learning, and which students have these experiences, instructors are able to make adjustments to their teaching which address both real and perceived issues. Student experience in this study highlighted five very clear themes in relation to the student experience of undertaking online oral communications tasks which all benefit from nuanced responses by the instructor: relevance; capacity; technology; time; and support.

Using well-designed OOCATs that diverge from more traditional written assessments can help students successfully engage with course content and develop oral communication skills. The student experience can be used to inform teaching by catering for different student learning styles and experience. Student centred approaches such as this allows instructors to reflect upon the assumptions they hold about their students and how they learn. This understanding can help inform adjustments to teaching approaches to support improved student experience of learning oral communications tasks.

The importance of learning oral communication skills in tertiary education is widely acknowledged internationally, however, there is limited research on how to teach these skills online in a way that is student centred. This research makes a contribution toward addressing that gap.

The purpose of this paper is to better understand the role that leadership plays in the success of Lean management (LM) implementation, by trying to identify what is the impact of the transactional, transformational, directive and empowering leadership styles on the success of such an implementation in Portuguese companies, and what are the most important leaders’ attributes.

An on-line questionnaire was distributed to 65 manufacturing and services Portuguese organizations that have implemented LM.

The results suggest that the empowering leadership style has a positive impact on the success of LM implementation. Even though results do not allow concluding about the impact of the other styles, several leader’s attributes were identified as having influence: individualized consideration, information sharing, skill development, intellectual stimulation, assigned goals and self-directed decision making.

Very few studies have addressed the role of leadership in the success of adopting LM and, to the best knowledge, only one paper studied the critical attributes of leaders in LM implementation. Moreover, the present study focuses in Portugal, country where this topic has rarely been investigated.

In the last few years, signs of material excess by organizational and political leaders have often evoked public outcry. The paper aims to argue that there is insight to be gleaned from drawing together strands from the leadership literature with the literatures on moral economy and conspicuous consumption. The premise is that views of leader conspicuous consumption are shaped by their moral economy, the interplay between moral attitudes and economic activities. The paper seeks to juxtapose tales of Cleopatra and Antony's display of wealth with current media accounts to contribute to the leadership literature on ethics, specifically its intersection with power and narrative representation.

The paper adopts an analytic approach, with an international orientation and an interdisciplinary perspective. It acknowledges the role of narrative representation in shaping leadership and the psychological ambivalence with which societies approach their leaders' practices, focus here on desire-disdain and discipline-decadence. Cleopatra and Antony's conspicuous consumption generated a legacy of condemnation for millennia. Drawing from the retellings of their story, four moralizing representations – by Plutarch, Shakespeare, Sarah Fielding and Hollywood – are analyzed and juxtaposed with current media accounts. Altogether, the paper combines the interest in leadership across history with moralizing perspectives on the display of wealth by leaders.

The intersection of the literatures on leadership, moral economy and conspicuous consumption draws together several dynamics of relevance to leadership. First, evaluations of the display of wealth on the part of a leader are contextual: they change across time and place. Second, interpretations of conspicuous consumption involve aesthetic judgment and so sit at the nexus of morality and taste. Third, following tragedies, tales of leader conspicuous consumption offer critics another knife to dig into the fallen tragic hero. Fourth, views of conspicuous consumption are gendered. Last, conspicuous consumption by leaders attracts condemnation through support for social responsibility and sustainability.

The paper establishes a novel articulation between the literatures on leadership, moral economy and conspicuous consumption.

There is increasing interest in the connection between Industry 4.0 (I4.0) and operational excellence approaches; however, studies on the integration between Six Sigma (SS) and I4.0 have been absent from the literature. Integration with I4.0 technologies can maximize the positive effects of SS. The purpose of this study is to understand what types of relationships exist between SS and I4.0 and with I4.0's technologies, as well as the benefits derived from this integration and future directions for this field of study.

A Systematic Literature Review (SLR) was carried out to analyze studies about connections between I4.0 technologies and SS. SLR analyzed 59 articles from 2013 to 2021 extracted from the Web of Science and Scopus databases, including documents from journals and conferences.

The SLR identified relationships between SS and several I4.0 technologies, the most cited and with the greatest possibilities of relationships being Big Data/Big Data Analytics (BDA) and Internet of Things (IoT). Three main types of relationships were identified: (1) support of I4.0 technologies to SS; (2) assistance from the SS to the introduction of I4.0 technologies, and, to a lesser extent; (3) incompatibilities between SS and I4.0 technologies. The benefits are mainly related to availability of large data sets and real-time information, enabling better decision-making in less time.

In addition, the study can help managers to understand the integration relationships, which may encourage companies to adopt SS/Lean Six Sigma (LSS) in conjunction with I4.0 technologies. The results also drew attention to the incompatibilities between SS and I4.0 to anticipate potential barriers to implementation.

The study focuses on three previously unexplored subjects: the connection between SS and I4.0, the existing relationships with different technologies and the benefits resulting from the relationships. In addition, the study compiled and structured different types of relationships for SS and I4.0 and I4.0's technologies, identifying patterns and presenting evidence on how these relationships occur. Finally, exposes current trends and possible research directions.

This paper gives the background to the ISO 18404:2015 standard and explains its rationale. It aims to rebut the Oudrhiri et al. (2022) paper. Furthermore, this paper adds further evidence of the misplacement and unfitness for use of the standard, as evidenced in the previous work by Antony et al. (2021, 2022).

A point-counterpoint methods approach with a literature review of studies available on ISO 18404:2015 to respond to the Oudrhiri et al. (2022) study.

The findings indicate that Oudrhiri et al.'s (2022) work is not open minded in relation to ISO18404. Each point raised in the Oudrhiri et al. (2020) study has been answered and counter argued.

Other than Antony et al.'s three studies (2021 and 2022) and Oudrhiri et al.’s (2022) study empirical studies looking into the impact of the ISO 18404 standard in the literature were limited. As the literature has shown, many companies are not utilising the standard given its current format; hence, a lack of information relating to the practical implementation is sparse.

The findings indicate that Oudrhiri et al.'s (2022) work can be answered and counter argued.

This study consolidates and strengthens the findings from the three studies by Antony et al. (2021 and 2022) and acts as a rebuttal to the Oudrhiri et al. (2022) study.
