constructs will be investigated using a multi-source research methodology whereby both
qualitative and quantitative research would be used. This would allow for generalisability in
reporting findings from the interview sessions without losing the nuances of the views of the
focus groups.
Research design
Based on the field of social sciences, a resign design is considered a logical sequence that
connects empirical data, the premise of the research question and finally its conclusions. This
research study shall employ both implicit and explicit research design in the form of case study
approach..
Justifying the case study approach
Case study approach will be employed in this research study to bring about the
intellectual practice of the researcher and the ability to portray the most insightful ethical
narrative from a contemporary phenomenon. Case study approach would be appropriate because
it would utilize the exploratory phase of the research topic to bring about the needed information.
Alternatively, since data would be examined in a natural setting, the complexity of ethical
concept would be studied extensively, and hence the study will be within an organizational
perspective.
Selecting a sample
Based on the complexities of the research topic, theoretical sampling process would be
applied to determine the appropriate study sample size. Theoretical sampling will be significant
because it encompasses processes that allow data analysis to be inspected as the emergent theory
develops. Theoretical sampling allows for more focused session of data collection, thus the study
will employ a population sample that can be used to collect the required data until the point when
the saturation point is attained. In this context, data will be collected until the instance when data
analysis shows that further data collection would not result to any new knowledge development.
Reliability and Validity
Reliability and validity are considered the two most significant approaches used for
evaluation of research designs. Evaluation of the population sample size of this case study
research design would employ the four logical tests such as external, internal, validity and
reliability constructs. Construct validity would be achieved by first highlighting the ethical
concept from the comprehensive review of the literature review. Internal and external validity
would be addressed by triangulating multiple sources of evidence. For instance, data in this study
would be collected using a combination of interviews and focus group sessions; the external
validity would be achieved by ensuring the research findings are generalisable beyond the
