The goal of the study determines the used research design. The researchers can use the convergent design in order to make people understand the topic more completely or validate the quantitative scales.

The embedded design is preferred in experimental study for preliminary exploration or follow-up explanation or more complete understanding of the experimental trial.

Lastly, multiple phase design is implemented to develop, adapt or evaluate program, multilevel statewide studies
