Writers present very different descriptions of what constitutes ‘ethnography’ and ‘case study’. While not attempting to review the literature, nor to comment on or endorse the overall quality of argument and presentation of research methodology made by each of the authors considered here, the following demonstrates how different the explanations and definitions offered can be.

Case study research has been applied across numerous fields and provides an established methodology for exploring and understanding various research contexts. This paper aims to aid in developing methodological rigor by investigating the approaches of establishing validity and reliability.

Based on a systematic review of relevant literature, this paper catalogs the use of validity and reliability measures within academic publications between 2008 and 2018. The review analyzes case study research across 15 peer-reviewed journals (total of 1,372 articles) and highlights the application of validity and reliability measures.

The evidence of the systematic literature review suggests that validity measures appear well established and widely reported within case study–based research articles. However, measures and test procedures related to research reliability appear underrepresented within analyzed articles.

As shown by the presented results, there is a need for more significant reporting of the procedures used related to research reliability. Toward this, the features of a robust case study protocol are defined and discussed.

Case studies continue to be a signature teaching tool for developing leadership educators in a classroom setting. However, many of these cases tend to be generic and may limit student learning. In order to maximize the learning potential of case studies, we advocate for the use of peer-authored, real-to-life case studies written from a first-hand experience as a training tool for graduate and doctoral-level leadership students. Students author a case based on a real-to-life issue, share with a classmate, and analyze collaboratively. This form of training allows leadership students to examine a case through multiple lenses while processing with a peer who may still be dealing with the leadership issue in real time. The culminating process allows students to examine the issue with direct feedback from another who lived the experience, completing a true 360-degree examination of a real-to-life controversy. This process supports deep reflection, leadership competencies, and metacognition of a dilemma. The assignment outlined in this application manuscript can be completed face-to-face or online and can be modified to work with any leadership learner group or program.

The recent global COVID-19 pandemic has forced many institutions of higher education to place added consideration and focus on their virtual instruction, causing instructors to rethink their pedagogical approaches (Murphy, et al., 2020). While new pedagogical technologies are being introduced in higher education (Baker, et al. 2008), not all approaches have produced beneficial results (Heilesen, 2010). Could this new learning medium serve as an effective tool for student learning outcomes and comprehension of course concepts? The current study presents attempts to answer these questions through its exploration of student perceptions and impact of podcasting as an instructional tool within four undergraduate leadership courses. Through the use of podcasting as a means of supplemental content and assessment, these cases provide educators with foundational guidance and recommendations on how to most effectively implement different ways of podcasting into the classroom to achieve student learning outcomes. As we celebrate the 20th anniversary of JOLE and look ahead to the next twenty years, the authors suggest that one of the most important tasks for leadership educators will not only be to recognize opportunities presented by technological advances in teaching and learning (Gigliotti & Ruben, 2017), but also the use of these new technologies to meet the needs of a changed student population in a post-global pandemic world.

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.

INTRODUCTION This paper examines some of the issues which arise from management research which develops theory from case studies. It first raises some fundamental questions which arise when case material is used in management research. For example, confusion surrounds the distinctions between qualitative data, inductive logic and case study research. Further, the processes of building theory from case studies lacks clarity. To help clear up some of these matters several research programmes are described in which the author has been personally involved and which developed theory from case studies. These case studies are used as illustrations of the multiple ways that case material might be used. Although every researcher has his/her preferred approach, it is concluded that case studies may be built up in a number of ways from, on the one hand, deep single case studies to multiple case studies using comparative logic, on the other. Between these two extremes are a number of hybrid methods which use both approaches.

The purpose of this paper is to examine the extent to which South African accounting academics use case studies in their teaching and to establish their views on whether this method can be used to transfer soft skills (also known as pervasive skills) to students.

An electronically administered questionnaire was sent to South African accounting academics.

Prior research provides evidence of the value of case studies in the transfer of soft/pervasive skills to students. The findings reveal that case studies are used less frequently by South African accounting academics than their international counterparts, because of a lack of awareness by South African accounting academics of the competencies that can be transferred using case studies, and the application of alternative teaching methods.

This paper provides insight into the use of case studies by academics in a developing country whose traditional strengths were in technical teaching, and the reluctance of the majority of South African accounting academics to embrace case studies into their academic programmes.

Several researchers struggle with designing, writing-up and reviewing case study research, but constructing a template for describing and justifying methodological choices is – in contrast with quantitative research – undesirable due to the creative nature of qualitative research. Therefore, the purpose of this paper is to provide insight into the multitude of paths to rigorous case study research and promote rigorous case study research in the service community.

Based upon a review of seminal articles and textbooks, different paths to rigorous case study research are identified. Subsequently, these paths are compared with existing practices in case studies in service research published between March 2017 and April 2019.

Seminal articles and textbooks detail different paths to achieve rigor with regard to research purpose, design, data, analyses and write-up. Overall, the most popular paths in the service community are those proposed by Eisenhardt and Yin. Meanwhile, service researchers increasingly challenge the dichotomy between the inductive and deductive logic by choosing an abductive logic. Transparency and reflexivity are the main points of attention among service researchers doing case study research.

By providing insight into the multitude of paths to rigorous case study research along with their popularity in the service community, this paper helps service researchers to balance rigor and creativity when engaging in case study research. Additionally, this paper offers a framework for reviewing case study research in terms of rigor and creativity.
