The effectiveness of Six Sigma programs has varied across different industries and organizations, and leadership styles have been identified as a critical success factor for the installation of Six Sigma initiatives. Therefore, this study aims to investigate the specific elements of leadership styles that are linked with the successful deployment of Six Sigma programs in the automobile industry.

To conduct the study, the researchers utilized a Likert scale questionnaire with a rating system of 1–7 and a simple random sampling method. The survey was distributed to 2,325 potential participants, with 573 responses received, mostly from Germany, the United Kingdom and Sweden. Out of those responses, 260 completed questionnaires were received. The study utilized a mixed-methods research design and exploratory research approaches to investigate the implication of leadership style on the success of Six Sigma implementation. The research employed several analysis techniques, including Structural Equation Modeling (SEM), exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and Survey methods.

Through various SEM methods, such as EFA and CFA, the study revealed two vital leadership elements: (1) the long-term success of Six Sigma depends on leadership’s support and recognition of it as an improvement strategy and (2) leadership must commit to the organization’s suppliers to ensure quality and the provision of defect-free products.

By incorporating the identified key elements of leadership into their strategies, organizations and researchers can ensure the sustainable implementation of Six Sigma.

This research presents a distinct contribution to the evaluation of leadership style components within the European automotive sector, utilizing a mixed-methods research design and incorporating a variety of descriptive statistics.

The study aims to define the term “generation” by proposing an integrated design based on age-period-cohort effects and by proposing an Indian generational cohort framework categorizing Indian generational cohorts into four categories, namely, Baby Boomers, GenX, GenY, and GenZ. The study further aimed to capture the existing generational differences between GenY and GenZ cohorts in the Indian teams on team climate, transactive memory system, and team leader humility.

For the first two objectives a literature review methodology along with the author's proposition was adopted. An integrated design was proposed by reviewing the relevant sociological literature to define generations. Thereafter, an Indian cohort framework was proposed categorizing them into four groups Baby Boomers, GenX, GenY, and GenZ. Following that, for the last objective, i.e. to identify the differences between cohorts, empirical data were collected by a structured questionnaire that was disseminated to GenY and GenZ Indian working professionals. A total of 229 responses were used for observing the differences or similarities between GenY and GenZ cohorts on the study variables by employing an independent samples t-test.

The study proposed an integrated design (age, period, and cohort effect). Following that, an Indian generational cohort's framework has been outlined categorizing Indian cohorts based on their birth years, age groups, developmental stages, formative years, major Indian historical events, and various characteristics possessed by them. Moreover, the empirical findings support the existing generational disparities and depict that GenZ holds a higher inclination towards transactive memory systems and team climate whereas GenY holds more inclination toward leader humility.

The study put forth its contribution to research scholars by categorizing Indian generational cohorts in a rationalized manner based on an integrated design (age-period-cohort) effect. The study would further assist concerned authorities and managers in formulating HR policies to deal with the underlying generational differences highlighted by the study.

As there lies a paucity of generational frameworks in the Indian context, this study is the first attempt in this direction which categorizes Indian generational cohorts based on a unique integrated design including age-period-cohort effects. In addition, the study also investigated these cohorts in Indian organizations to observe the existing variations.

This study explored how organizational leaders at different hierarchical levels may communicatively enhance employees' health and well-being. Drawing on interdisciplinary research, it proposed a model that connects health-oriented leadership communication at supervisory and executive levels with remote workers' self-care and stress levels during the COVID-19 pandemic.

Data collected through a survey of 363 full-time United States (US) employees were analyzed to test the model.

Results showed health-oriented communication at the two leadership levels directly influenced employees' self-care, which in turn reduced their stress levels. Further, executive leaders' health-oriented leadership communication indirectly impacted remote workers' self-care through its positive association with supervisors' health-oriented leadership communication.

This study offers much-needed guidelines for executive leaders, supervisors and communication practitioners seeking to meet employees' growing expectations for a healthy work environment in today's post-pandemic era.

Although the literature has established organizational leadership as a vital determinant for a healthy workforce, few studies have explored leaders' health-specific communication to enhance employee health. This study is the first to conceptualize health-oriented leadership communication at dual hierarchical levels and uncover its influence on employees. The results suggested the importance of health-oriented leadership communication across hierarchical levels in building a healthy workplace.

Emotions are everywhere and, as multiple scholars have argued, can be considered a fundamental part of the human experience. Individuals are expected to behave in socially appropriate ways in a variety of public and private social situations, which often involve managing one's emotions. The management and regulation of emotions are also key components of effective school leadership. This chapter unpacks the emotional aspects of school leadership by exploring how the management of emotions is fundamental to the success of headmasters, principals, vice-principals, and other school-level leaders. I also provide the rationale for using the term ‘school-level leaders’ and call for emotional authenticity in educational leadership. Then I outline several benefits an increased scholarly and practical focus on the emotional aspects of school-level leadership offers for teachers and other school staff, school-level leaders themselves, and the students they serve on a daily basis. I also provide a short description of the methodology used for the participant quotes used to add richness and contextualize key themes explored in Chapters 4 and 5. The chapter concludes with an outline of how the rest of this book is organized and offers additional insight into the topics explored in the forthcoming chapters.

The modern construction industry is highly competitive and cost driven, with tangible adversarial relationships between projects' contractual parties at individual and organisational levels; there are conflict of interest as people to survive. Accordingly, team leaders on construction megaprojects (CMPs) in multinational engineering organisations strive to survive in such competitive markets. The research’s aim is to investigate relationships between team leaders' tenure and management styles towards professional subordinates on CMPs and elaborate how corporate governance can optimally address this conflict of interest and adversarial relationships.

The research methodology adopted processes of inducting theory using case studies. A qualitative approach was adopted as a primary data collection and analysis source. It involved case studies through primary data collection in semi-structured face-to-face interviews with 38 professional subordinates (interviewees) to discuss impacts of team leaders' tenure on their management style (a five-team leader, case studies). The research methodology is based on building theories from case study grounded theory research methodologies.

The research introduced the notion that team leader survival syndrome is pronounced and evidenced by adversarial reactions towards new or experienced professional subordinates where team leaders perceive professional subordinates, especially at senior technical levels, as potential risks that jeopardise their positions and employment survival possibilities. The syndrome is proven based on real-life case studies; it is constant, tangible and serious disorder of attitudes and behaviours. Longer tenure stimulates and accelerates these phenomena and syndrome, with 58% of team leaders exhibiting such syndromes. Optimum employee tenure is between 7 and 10 years. Corporate governance provides good resolution practices.

The research implications are useful to construction industry and academia. However, the analysis is limited to the case studies considered in Canada and Qatar. Due to small sample size for both case studies and respondents to the questionnaire survey, it is recommended for future exploration to expand the scope of research to larger sample size and various demographic and geographical locations.

Corporates should acknowledge the presence of team leader survival syndromes. They should thoroughly investigate sociopolitical relationships behind it and seek to understand consequences on professional subordinates. Corporates should also adopt a 360-degree feedback system; they should limit trust given to team leaders in this regard to responsible trust, to eliminate manipulation. Team leaders are perceived as being not always truthful and misrepresent capabilities and performance of their professional subordinates to senior managers. Corporate governance holistic multidimensional perspectives are required to provide resolutions of team leader survival syndromes.

The research has discovered a phenomenon that team leaders on CMPs in architecture, engineering and construction (AEC) organisations, prompted by virtue of long tenure in corporates or by power of their managerial level in organisations, perceive their professional subordinates, especially senior technical employees, as potential risks. It is thought promoting them would put their own positions and security of tenure at risk. Hence, team leaders act adversarially, to enhance their own survival prospects. This research introduced the novel team leader survival syndrome and introduced analyses, practical implications and recommendations.

This chapter offers a comprehensive review the literature on authentic leadership (AL). The authors employ a bibliometric approach to identify, classify, visualise and synthesise relevant scholarly publications and the work of a core group of interdisciplinary scholars who are key contributors to the research on AL. They review 264 journal articles, adopting a clustering technique to assess the central themes of AL scholarship. They identify five distinct thematic clusters: authenticity in the context of leadership; structure of AL; social perspectives on AL; dynamism of AL; and value perceptions of AL. Velt and Sinkovics assert that these clusters will help scholars of AL to understand the dominant streams in the literature and provide a foundation for future research.

The importance of modeling digital leadership in quickly digitizing countries, like the United Arab Emirates (UAE), is inevitable for building leadership capabilities to lead, engage and motivate remote employees in the digital environment. Using Blake and Mouton Grid, the current study examines the behavioral approach used by the leaders from both public and private sectors while managing their workforce digitally in the period of the pandemic, when 70% of the workforce worked remotely for the first-time in the region.

An online survey was conducted by the managerial employees working in different firms using self-administered questionnaires and adopting the snowball sampling technique. In total, 476 respondents participated in the study from both the Emirates of Abu Dhabi and Dubai.

The analysis using IBM SPSS and Smart PLS software reported that 9 out of 10 leaders positioned their digital leadership style well above the middle-of-the-road management style (5,5) oriented towards team management (9,9); with 7 out of 9 displaying high team management leadership style, while managing remote workers. However, millennials displayed higher task orientation when compared to generation-x leaders, who concentrated more on their relations with the workers.

The findings have implications for practitioners in technology driven regions. Also the results highlighting the task-oriented approach of millennials digital leaders have implication for owners and board of directors of the firms that seniority is not the only credible approach for leadership positions.

The study reveals the behavioral styles beneficial for digital leaders to develop their leadership capabilities and increase their effectiveness while managing the workforce digitally. Black Mountain Grid and its two-dimensional leadership matrix has been found to be a useful conceptual approach for understanding digital leadership behaviors, and based on study findings, recommendations have been provided to effectively improve its utilization for leading teams. The findings have implications for practitioners in technology driven regions as well as digital leadership field scholars.

Innovation for service contributes to service quality and customer satisfaction, and further benefits service-centered organizations to sustain competitive advantages. However, concurrent mediating and moderating mechanisms underlying innovation for service at both the group and individual levels have been scarcely investigated. The purpose of this study is to explore multilevel mediating and moderating mechanisms behind the relationship between dual-level transformational leadership (TFL) and innovation for service at the group and individual levels.

Data were collected from two countries (i.e. China and Australia). Multilevel structural equation modeling was employed to validate the research model. Bootstrapping with 5,000 replications and latent moderated structural equation modeling were used to respectively examine the mediating and moderating mechanisms.

The cross-national results showed that task interdependence and creative role identity respectively played as the group-level and individual-level mediating roles between TFL and innovation for service. It was also found that task interdependence played as a cross-level predictor enhancing individual innovation for service. Task interdependence was a moderator on the relationship between individual-level TFL and creative role identity among Australian employees, but not among Chinese employees. The relationship between creative role identity and individual innovation for service was not moderated by task interdependence among both Chinese and Australian employees.

This study contributes to advancing the TFL–innovation research through revealing dual-level TFL as the antecedent of innovation for service at both the group and individual levels. It also extends the understandings of the mediating and moderating mechanisms behind this dual-level relationship between TFL and innovation for service.
