I have recently conducted a set of qualitative interviews with a particular group. Their interviews yielded interesting info about a certain phenomenon. However, based on the information gathered from the first group of interviewees, it led me to a different type group whom I also conducted interviews with in order to explain/expand the first group's perspectives.
So it was a sequential process that I couldn't have planned beforehand without coming across the info gathered from the first group.
When parsing this information in a research manuscript (under methodology section), is it perfectly okay to explain the process of how I did or is there a set of framework out there that explains what I just did?
