Qualitative Research Design Case Study

Qualitative Case Study Assignment

Introduction

The qualitative case study serves as a research methodology that enables the exploration of a specific phenomenon within a particular context, utilizing various data sources. This approach examines the phenomenon from multiple perspectives, unveiling its diverse facets (Baxter & Jack, 2008). By investigating real-time occurrences within their natural contexts, case studies acknowledge the influence of the surrounding circumstances (Kaarbo & Beasley, 1999).

A case study is a commonly employed methodology within qualitative research (Yazan, 2015). Nevertheless, due to the lack of well-structured and comprehensive protocols, it has not established itself as a fully recognized social science research strategy (Yin, 2002). Consequently, novice researchers who intend to utilize this methodology often face confusion regarding the essence of a case study and its distinction from other qualitative research methods (Merriam, 1998).

While a considerable amount of literature exists on the theory and application of qualitative research (see Creswell, 2013; Marshall & Rossman, 2014; Merriam & Tisdell, 2015), these studies generally provide only a superficial overview of case study research (Hancock & Algozzine, 2016).

Despite being widely employed in academic research, researchers still lack consensus regarding the planning and implementing of case studies, hindering their complete development (Yazan, 2015). However, a few studies on case study methodology (Hancock & Algozzine, 2016; Yin, 2017) have attempted to synthesize details and offer a comprehensive process and practical guidelines for conducting case study research.

Academic researchers often rely on the procedures proposed by influential authors such as Robert K. Yin, Sharan Merriam, and Robert E. Stake when conducting case study research (Creswell, Hanson, Clark Plano, & Morales, 2007). These methodologists significantly impact the decision-making process of researchers when it comes to case study design (Yazan, 2015).

Prominent books on case study methodology (Merriam, 2002; Stake, 1995; Yin, 2011) provide valuable insights into case study research. However, they tend to prioritize theory over practice; offering beginners limited guidance in conducting case studies (Hancock & Algozzine, 2016).

In healthcare research, the utilization of the qualitative case study (QCS) approach has seen a rise over the past decade (Anthony & Jack, 2009). Researchers frequently cite the works of Robert Yin and Robert Stake to support their chosen methodology. However, Yin (2009) and Stake (2005) hold differing philosophical orientations, and their work is often applied and cited without considering these philosophical perspectives, thereby undermining the credibility of the research conducted. Yin’s work, rooted in a postpositivist perspective, has been more commonly represented, whereas Stake’s constructivist approach has received less attention (Rashid et al., 2019).

Qualitative Research Design: Case Study

Creswell (2013) defines the QCS approach as an exploration of a “bounded system” or case over time through comprehensive data collection involving multiple sources of information, each employing its sampling, data collection, and analysis strategies. The outcome is a case description consisting of case-based themes. The QCS approach is often regarded as a contextually based tradition, where it becomes challenging to separate the case from the context in which it unfolds. Creswell argues that the type of case study conducted depends on the scale of the bounded case or the purpose of the analysis (Rashid et al., 2019).

Researchers across various disciplines have utilized the QCS approach to enhance our understanding of individuals, groups, processes, and relationships (Yin, 2009). As contended by Stake (2005), Merriam (1988, as cited in Boblin et al., 2013), and Yin (2009), the case study approach enables a holistic comprehension of a phenomenon within real-life contexts, as perceived by those involved. Stake describes the case study approach as a means of capturing the intricacies of a phenomenon. Case studies are particularly suited to research that explores “how” and “why” questions (Stake, 2005; Yin, 2003).

The Yin and Stake Perspective

The viewpoints of researchers regarding the nature and generation of knowledge, or their epistemological inclination, fundamentally shape the inquiry projects they conceive and undertake. It influences every aspect of the research process, from selecting the investigated phenomenon to the final report’s composition. According to Merriam, “Research ultimately aims to produce knowledge about the world, specifically the realm of educational practice” (Merriam, 1998, p. 3, as cited in Boblin et al., 2013). As researchers and methodologists, Yin, Merriam, and Stake possess epistemic commitments that influence their perspectives on case study methodology. They also guide novice researchers on approaching case study methods in their research endeavors. These commitments are explicitly or implicitly evident in their seminal texts on case study research, shaping their conception of the case study. Therefore, before delving into my analysis, I will draw upon Yin, Merriam, and Stake’s particular epistemological orientations, which will inform the subsequent analysis.

Yin’s perspective on the case study demonstrates a leaning toward positivism. Crotty (1998) identifies three fundamental notions of positivistic research orientation: objectivity, validity, and generalizability. If researchers claim that the findings of their proposed study will be “facts, or at least as close to fact as their research has enabled them to reach,” it suggests that their research is underpinned by the positivist philosophical tradition (Crotty, 1998, p. 41). Although Yin does not explicitly articulate his epistemological orientation in his text, his approach to case study and research, as well as the aspects he emphasizes, strongly indicate a philosophical stance aligned with positivism. For instance, from a Yinian perspective, a case study researcher is expected to “maximize four conditions related to design quality: construct validity, internal validity, external validity, and reliability. How investigators deal with these aspects of quality control” (Yin, 2002, p. 19) is crucial at every step of the case study research. Yin consistently suggests that emerging researchers should keep these four “yardsticks” in mind throughout their inquiry process to ensure the quality of their investigation. Hence, based on Crotty’s understanding, Yin’s perspective on case study research can be seen as grounded in positivism.

Furthermore, Yin’s perspective on the dichotomy between quantitative and qualitative research traditions might explain why he avoids explicitly addressing his philosophical orientation. He rejects the notion of qualitative and quantitative orientations being fundamentally distinct due to irreconcilable philosophical disparities, stating that regardless of personal preference for qualitative or quantitative research, it is crucial to recognize a significant and fundamental overlap between the two approaches. (Yin, 2002, p. 15). Yin focuses on the shared elements of these two research traditions and pragmatically emphasizes the common tools that can be functional and instrumental in the design and methods of the case study he proposes, thereby blurring the boundaries between quantitative and qualitative case study methods.

In contrast to Yin, who appears to evade making statements about his epistemic commitments or the preferred epistemology guiding case study methodology, Stake dedicates a significant portion of a chapter in his text to explaining the epistemological tradition that qualitative case study researchers should adhere to. He argues that “how case study researchers should contribute to reader experience depends on their notions of knowledge and reality” (Stake, 1995, p. 100). From a Stakian perspective, constructivism and existentialism (non-determinism) should be the epistemologies that shape and inform qualitative case study research, as according to the majority of modern qualitative researchers, it is widely accepted that knowledge is not something that is discovered, but rather something that is actively constructed. (Stake, 1995, p. 99). Therefore, Stake primarily envisions qualitative case study researchers as interpreters and gatherers of interpretations, requiring them to report their rendering or construction of the constructed reality or knowledge gathered through their investigation. From Stake’s perspective, qualitative researchers should anticipate another level of reality or knowledge construction to occur on the part of the readers of their report in addition to the two levels previously mentioned.

This deduction is also relevant to Stake’s assertion that in the case at hand, it is important to acknowledge that numerous perspectives or viewpoints should be included and accounted for. However, it is impossible to establish the ultimate, indisputable perspective, as different views may be subject to debate and lack a clear hierarchy. (Stake, 1995, p. 108).

The Process of Case Study Design

Yin places significant importance on the design of case studies, as evident from the subtitle of his book. He acknowledges that, unlike other research strategies, a case study lacks a “codified design,” which may contribute to its diminished recognition as a notable research method (Yin, 2002, p. 19). Yin recognizes the need for a comprehensive catalog of research designs specifically tailored for case studies and takes it upon himself to address this gap. Consequently, he presents a meticulous and comprehensive approach to designing cases, meticulously examining each step of the research process, from formulating research questions to data collection, analysis, and reporting.

According to Yin (2002), design is the logical sequence that connects empirical data to a study’s initial research questions and, ultimately, its conclusions (p. 20). To aid case study researchers, Yin suggests four types of designs: single holistic design, single embedded design, multiple holistic designs, and multiple embedded design. Holistic designs focus on a single unit of analysis, while embedded designs involve multiple units of analysis. Yin advises novice researchers to select a design that best serves their research questions, considering each design’s strengths, limitations, and potential pitfalls.

From Yin’s perspective, case study research design comprises five components: the study’s questions, propositions (if any), unit(s) of analysis, the logical connection between data and propositions, and criteria for interpreting findings. The researcher must ensure that these components are coherent and consistent with each other throughout the design process. Yin places particular emphasis on the fourth and fifth components, which pertain to planning the data analysis steps in case study research. He advises researchers to meticulously and rigorously plan these “least well-developed components” to establish a solid foundation for analytical operations (Yin, 2002, p. 26). Additionally, Yin highlights the necessity of reviewing relevant literature and incorporating theoretical propositions related to the case under study before commencing data collection—a distinguishing factor from methodologies like grounded theory and ethnography.

Regarding case study design, Yin proposes four criteria for measuring design quality: construct validity, internal validity, external validity, and reliability. Researchers striving for rigorous and robust case study designs must maximize these conditions throughout the inquiry process. Yin also stresses the importance of preparing a detailed design at the outset of the research, allowing for minor adjustments during data collection. However, in the event of major alterations, researchers should return to the conceptualization stage and redesign the study accordingly.

In contrast to Yin’s structured approach, Stake advocates for a flexible design that permits researchers to make significant changes even after progressing from the research design. The only initial design Stake proposes is related to issues and issue questions, subsequently leading to the formulation of research questions. From Stake’s perspective, investigators employ issues as a conceptual structure to emphasize complexity and contextuality as they draw attention to the case’s problems, conflicts, and multifaceted aspects (Stake, 1995, pp. 16-17). Stake provides valuable advice regarding initiating two types of case studies: intrinsic and instrumental. The case itself is of utmost importance for intrinsic case studies, while for instrumental case studies, the issue takes precedence (Stake, 1995, p. 16).

Although Stake does not specify a particular point in the research process to begin data collection and analysis, he emphasizes the significance of having a set of two or three evolved or developed issue questions (research questions) that guide the observation, interviews, and document review (Stake, 1995, p. 20). These questions are derived from an initial pool of ten or twenty substantive questions, narrowed down through the researchers’ preliminary interactions with the case, personal experience, and relevant literature. Stake’s flexibility in case study design stems from his endorsement of “progressive focusing,” an idea initially introduced by Parlett and Hamilton (1976). While Stake’s flexible approach may appeal to novice investigators due to its reduced design preparation requirements compared to Yin’s approach, embarking on the research journey without a well-prepared design and timeline can lead to confusion or impasse. Even experienced researchers may benefit from a meticulously planned design before commencing their inquiry. However, Stake’s advocacy for qualitative research may introduce uncertainty and ambiguity for emerging researchers, as clear guidelines may be lacking.

Use in Public Administration

Numerous reviews of scholarly articles on public administration (e.g., Gill & Meier, 2000; Kettl, 2000; Ongaro, 2008) reveal the numerous uncertainties that characterize this field of knowledge. According to the author, these uncertainties arise from the interplay between subject matter, approach, and theoretical frameworks employed in those articles (Guerra et al., 2013).

Kettl (2000) asserts that one of the primary deficiencies in public administration research is the prevalent use of inadequately developed or unsuitable methodologies for the studied subject. Boyne (2004) similarly questions the lack of rigor in evaluating issues related to the services provided by public administration, both in theory and practice. In other published works, Boyne (2002) discusses the importance of quantitative methods in publications within this field while emphasizing the significance of the subjects and objectives of academic research in public administration (Boyne, 2003).

Roesch (2003) discusses the scientific output on administration and proposes improved methodological guidelines, suggesting that globally developed research methods and techniques are available for use, testing, or adaptation to local conditions and circumstances. However, Roesch notes that few researchers employ the most up-to-date methodology to analyze empirical research, either because it is perceived as overly complex or due to the purported lack of funding for extensive databases (p. 166). Conversely, the potential of qualitative research is seldom adequately explored, particularly in case studies where the analysis of empirical material tends to be weak, obscured by prescriptive tones, and lacking in efforts to abstract generalizations or construct local theories (Roesch, 2003, p. 166).

Similarly, critics of publications in the field of public administration primarily focus on the methodological aspects of research. In addition to the studies above, Fleury, Bloch, Bravo, and Bicudo (2003), in their analysis of articles published in the Public Administration Magazine (Revista de Administração Pública [RAP]) between 1992 and 2002, found that case studies were employed as a research strategy in 32% of the reviewed articles. These findings are corroborated by Hocayenda-Silva, Rossoni, and Ferreira (2008).

Conclusion

Prospective researchers often search for a research methodology once they have determined their research question(s) and chosen their phenomenon of interest. If they opt for a case study approach, they are confronted with many approaches and a contested terrain characterized by various perspectives. This paper aims to assist such researchers in three ways that set it apart from generic case study texts. Firstly, novice case study researchers will comprehend the relationship between their epistemic orientations and the case study approaches they lean toward. In other words, they will recognize that their research-related decisions reflect their emerging identities as educational researchers. Secondly, this paper presents the perspective of another novice case study researcher who has undergone similar processes of designing and conducting a case study research, which provides valuable insight for those about to embark on the same journey. Lastly, by being exposed to various case study approaches in this paper, emerging researchers can selectively combine elements (e.g., diverse research techniques and strategies) from each approach that best serve and support their research design. Therefore, it is believed that this comparative analysis of three different renditions of case study methods can serve as a helpful, quick reference for emerging researchers during the conceptualization and design of their research projects.
