The process followed to select a research design include comparison of advantages and disadvantages and at the same time trade-offs of selecting a particular design (Younas & Durante, 2023; Natow, 2020). Comparatively, case study design has an advantage to enable researcher for identifying omissions or new hypotheses and variables, examination of intervening variables, constructing historical explanation of various situations, high-level construct validity and using contingent generalisation (Miller et al., 2020). Further, case study design is selected owing to flexible nature offered for allowing application of various research methods (Cerar et al., 2021). The trade-offs in selecting a case study design entail issue with case selection and issues evidenced by selection biasness having immense impact as opposed to pure statistic design (Rezigalla, 2020). Additionally, generalisation of the case studies is contingent on similar conditions between cases and where it is generalised. The primary weakness of using case study is representativeness of findings obtained to general population of target.
An awareness of the different advantages, limitations and trade-offs, it is clear that case study design is the most appropriate for the current research. To begin with, case study design facilitate researcher to use qualitative (interviews) and quantitative (surveys) within a specified context. Also, the richness issues are not relevant in this research since the start is sourcing for a problem solution in an organisation hence limiting the study to one case enhancing richness level. In regard to parsimony, design allows research to identify appropriate research methods less costly. For example, for the surveys, the costs is lower as it was done online through a google enabled platform as opposed to paper-based surveys. Considering the online platforms lower the incurred costs/expenses, time is also lowered inclusive of the time to be used to travel, call for an appointment and entering data from the software programs.
In this research, quantitative research was preferred due to a set of reasons. To start with, as evidenced in Fainshmidt et al. (2020), the manner in which the quantitative research is pursued provide a relevant chance to support an appropriate support a detailed test of hypothesis. For instance, through the application of quantitative research, it is possible to test the impact of the noted independent variables which are motivation, organisation performance, productivity and motivation with the dependent variable being the employees turnover and retention. In line with Khmil et al. (2019), statistical data reliability level is evidenced in the quantitative in a way that the researcher is in a position of leveraging on less engagement with various research respondents. The outcome of this is avoidance of biasness which have a high likelihood of distortion of the obtained research findings. This is different in qualitative research where it entail engaging the investigator playing an active role in the research being a catalyst. As evidenced in Yang et al. (2020), the outcome of this is an increase in bias in research. Further, albeit of the identified advantages associated with use of quantitative research, the quantitative research also has their disadvantages. These entail the implementation of the research in a tightly controlled environment. The outcome of this include richness and detailed nature of the research. Further, the quantitative data is limited in regard to its effectiveness, this would be reviewed by considering the relationship existing among the different study variables such as the impact of turnover on the organisations performance and profitability.
As illustrated in table 1, there are a set of differences of quantitative and qualitative research;
Table 1: Differences of Quantitative and Qualitative Research
Therefore, as shown in table 1, for the purpose of gathering appropriate insights on impact of turnover on organisations performance and productivity, quantitative research has been applied. Further, the identified research question, the dependent variable and independent variables would be investigated for identifying their correlation. By working on this, quantitative research would be appropriately applied.
