The E-interview Research Framework is round, not because you want to go around in circles, but because you do want to see the inter-relationships between various design decisions. Nowhere is this more true than in the alignment of data collection methods-- your online interviews and observations-- with the purpose of the study.
I am attaching a worksheet you can use, if you are willing to share your research design map with the group. It will be interesting to learn about your research-- whether you share a past, present or future example. Then, as we go through the rest of the seminar, you can check back and see if design elements change, or you have new insights, as you refine your ideas about online interviews and how they fit with the research.
