You should approach your inquiry as a student, not as an authority. Most of all, your work should be motivated by your desire to understand your topic, not by making predictions. As you can guess, this means you must be a very good writer. Qualitative design is holistic. It looks at the larger picture, the whole picture, and begins with a search for understanding of the whole.
Qualitative design looks at relationships within a system or culture.
Qualitative design requires ongoing analyses of the data. Qualitative design incorporates room for description of the role of the researcher as well as description of the researcher's own biases and ideological preference. Qualitative design is focused on understanding a given social setting, not necessarily on making predictions about thatsetting. Qualitative design demands that the researcher stay in the setting over time. Qualitative design demands time in analysis to time in the field.
