Quality Assurance Research Papers

The literature reviewed showed a lack of consensus between qualitative research approaches about how to assure quality of research. This reflects past and on-going debates among qualitative researchers about how to define quality, and even the nature of qualitative research itself. The two main narratives that emerged from the reviewed literature reflected differing approaches to quality assurance and, underpinning these differing conceptualisations of quality in qualitative research.

Among the literature that directly discusses quality assurance in qualitative research, the most dominant narrative detected was that of an output-oriented approach. Within this narrative, quality is conceptualised in relation to theoretical constructs such as validity or rigour, derived from the positivist paradigm, and is demonstrated by the inclusion of certain recommended methodological techniques. By contrast, the second, process-oriented narrative presented conceptualisations of quality that were linked to principles or values considered inherent to the qualitative approach, to be understood and enacted throughout the research process. A third, minor narrative offered critique of current and recent discourses on assuring quality of qualitative research but did not appear to offer alternative ways by which to conceptualise or conduct quality assurance.

Strengths of the output-oriented approach for assuring quality of qualitative studies include the acceptability and credibility of this approach within the dominant positivist environment where decision-making is based on 'objective' criteria of quality [11]. Checklists equip those unfamiliar with qualitative research with the means to assess its quality [6]. In this way, qualitative research can become more widely accessible, accepted and integrated into decision-making. This has been demonstrated in the increasing presence of qualitative studies in leading medical research journals [11, 12]. However, as argued by those contributing to the second narrative in this review, the following of check-lists does not equate with understanding of and commitment to the theoretical underpinnings of qualitative paradigms or what constitutes quality within the approach. The privileging of guidelines as a mechanism to demonstrate quality can mislead inexperienced qualitative researchers as to what constitutes good qualitative research. This runs the risk of reducing qualitative research to a limited set of methods, requiring little theoretical expertise [52] and diverting attention away from the analytic content of research unique to the qualitative approach [14]. Ultimately, one can argue that a solely output-oriented approach risks the values of qualitative research becoming skewed towards the demands of the positivist paradigm without retaining quality in the substance of the research process.

By contrast, strengths of the process-oriented approach include the ability of the researcher to address the quality of their research in relation to the core principles or values of qualitative research (see Table 2). For example, previous assumptions that incorporating participant-observation methods over an extended period of time in 'the field' constituted 'good' anthropology and an indicator of quality have been challenged on the basis that fieldwork as a method should not be conducted uncritically [53], without acknowledgement of other important steps, including exploring variability and contradiction [54], and being explicit about methodological choices made and the theoretical reasons behind them [55]. The core principles identified in this narrative also represent continuous, researcher-led activities, rather than externally-determined indicators such as validity, or end-points. Reflexivity, for example, is an active, iterative process [56], described as 'an attitude of attending systematically to the context of knowledge construction... at every step of the research process' [p484, 23]. As such, this approach emphasises the need to consider quality throughout the whole course of research, and locates the responsibility for enacting good qualitative research practice firmly in the lap of the researcher(s).

The question remains, however, as to how researchers can demonstrate to others that core principles have guided their research process. The paucity of guidelines among those advocating a process-oriented approach suggests these are either not possible or not desirable to disseminate. Guidelines, by their largely fixed nature, could be considered incompatible with flexible, pluralistic, qualitative research. Awareness and understanding of the fundamental principles of qualitative research (such as those six identified in this review) could be considered sufficient to ensure that researchers conduct the whole research process to a high standard. Indeed, it could be argued that this type of approach has been promoted within qualitative research fields beyond the health sciences for several decades, since debates around how to do 'good' qualitative research emerged publically [41, 43, 51]. However, the premises of this approach are challenged by increasing scrutiny over the accuracy and ethics of the generation of information through scientific activity [57, 58]. Previous critiques of a post-hoc evaluation approach to quality, in favour of procedural mechanisms to ensure good research [43], have not responded to the demand in some research contexts, particularly in global health, for externally demonstrable quality assurance procedures.

The authors propose, therefore, that some form of guidelines may be possible and desirable, although in a less structured format than those representing a more positivistic paradigm and based on researcher-led principles of good practice rather than externally-determined constructs of quality such as validity. However, first it is important to acknowledge some of the limitations of our search and interpretations.

Limitations

The number of papers included in the review was relatively low. The search was limited to publications explicitly focused on 'quality assurance', and the inclusion criteria may have excluded relevant literature that uses different terminologies, particularly as this concept has not commonly been used within qualitative methods literature. As has been demonstrated in the narratives identified, approaches to quality assurance are linked closely to conceptualisations of quality, about which there is a much larger body of literature than was reviewed for this paper. The possibility of these publications being missed, along with other hard-to-find and grey literature, has implications for the robustness of the narratives identified.

This limitation is perhaps most evident in the lack of literature in this review identified from the field of anthropology. Debates around concepts such as validity and what constitutes 'knowledge' from research have long been of interest to anthropologists [55], but the absence of these in the publications which met the inclusion criteria raises questions about the search strategy used. Although the search strategy was revised iteratively during the search process to capture variations of quality assurance, anthropological references did not emerge. The choice was made not to pursue the search further for practical and time-related reasons, but also as we felt that limiting the review to quality assurance as originally described would be useful for understanding the literature that a researcher would likely encounter when exploring quality assurance of qualitative research. The lack of clear anthropological voice in this literature reflects the paucity of engagement with the theoretical basis of this discipline in the health sciences, unlike other social sciences such as sociology [52]. As such, anthropology's contributions to debates on qualitative research methods within health and medical research have been somewhat overlooked [59].

Hence, this review presents only a part of the discourse of assuring quality of qualitative research, but it does reflect the part that has dominated the fields of health and medical research. Although this review leaves some unanswered questions about defining and assuring quality across different qualitative disciplines, we believe it gives a valuable insight into the types of narratives a typical researcher would begin to engage with if coming from a global health research perspective.

Recommendations

The narratives emerging from this literature review indicate the challenges related to approaching quality assurance from a perspective shaped by the positivist fields of evidence-based medicine, but also the lack of clear, structured guidance based on the intrinsic principles of qualitative research. We recommend that the strengths of both the output-oriented and process-oriented narratives be brought together to create guidance that reflects core principles of qualitative research but also responds to expectations of the global health field for explicitly assured quality in research. The fundamental principles characterising qualitative research, such as the six presented in Table 2, offer the basis of an approach to assuring quality that is reflexive of and appropriate to the specific values of qualitative research.

The next step in developing guidance should focus on identifying practical and specific advice to researchers as to how to engage with these principles and demonstrate enactment of the principles at each stage of the research process while being wary of promoting unthinking use of 'technical fixes' [6]. We recommend the development of a framework that helps researchers to identify their core principles, appropriate for their epistemological and methodological approach, and ways to demonstrate that these have been upheld throughout the research process. Current generic quality assurance activities, such as the use of standard operating procedures (SOPs) and monitoring visits could be attuned to the principles of the qualitative research being undertaken through an approach that demonstrates quality without constraining the research or compromising core principles. The development of such a framework should be undertaken in a collaborative way between researchers and field teams undertaking qualitative research in practice. We propose that this framework be flexible enough to accommodate different qualitative methodologies without dictating essential activities for promoting quality. Unlike previous guidance, we propose the framework should also respond to different demands from multi-disciplinary research teams and from external, positivist, audiences for evidence of quality assurance procedures, as may be faced, for example, in the field of global health research. This review has also highlighted the challenges of accessing a broad range of literature from across different social science disciplines (in particular anthropology) when conducting searches using standard approaches adopted in the health sciences. Further consideration should be taken as to how best to encourage wider search parameters, familiarisation with different sources of literature and greater acceptance of non-traditional disciplinary perspectives within health and medical literature reviews.

The development of increasingly-complex Web 2.0 applications, along  with a rise in end-user expectations, have not only made the testing and quality assurance processes of web application development an increasingly-important part of the SDLC, but have also made these processes more complex and resource-intensive. One way to effectively test these applications is by implementing an automated testing solution along with manual testing, as automation solutions have been shown to increase the total amount of testing that can be performed, and help testing team achieve consistency in their testing efforts. The difficulty, though, lies in how to best go about developing such a solution. The use of a framework is shown to help, by decreasing the amount of duplicate code and maintenance required, and increasing the amount of separation among the various elements of the testing solution.
This research examines the use of the UML Testing Profile (UTP), including the use of UML diagrams, in the creation of such a framework. Using an Action Design Research methodology, a framework is developed for an automated testing solution that utilizes the Selenium Webdriver with a data-driven methodology, used in an organizational context, and evaluated, over the course of multiple iterations. Design principles, including the use of a test architecture and test context, the use of UML diagrams for the creation of Page Objects, and the identification and implementation of workflows are distilled from these iterations, and their impact on the larger context, the delivery of a robust application that meets end-user expectations, is examined.
