It is guided by the researcher’s use of a specific theoretical perspective, as well as the concurrent collection of both quantitative and qualitative data. This perspective can be based on ideologies such as critical theory, advocacy, participatory research, or a conceptual or theoretical framework. This perspective is reflected in the purpose or research questions of the study. It is the driving force behind all methodological choices, such as defining the problem, identifying the design and data sources, analysing, interpreting, and reporting results. The choice of a concurrent model, whether it is triangulation or embedded design, is made to facilitate this perspective.
Concurrent designs are visually presented in Figure 3.
