After a good start, I am running into a little difficulty persuading potential respondents to participate in the interviews. I don’t of course expect everyone I ask to welcome the prospect of being interviewed with open arms, and it’s too early yet to give up on plan A. But I do need to think about a Plan B. This, will I think, involve having less of a focus on two institutions, and simply interviewing a wider selection of developers based in different institutions. After all, if I make sure that I get a good cross section of institutions, I can still draw legitimate conclusions about the influence of the institutional context. But I think my next task is to revisit some of the methodology texts on interviewing!
