I am designing a qualitative research (observation and semi-structured interviews) about the content and processes of knowledge sharing between young (receiver) and tenured members (transmitters) of an organization. The guidelines/questions are already prepared. However, I am missing a last and delicate element: how can I assess the actual giving and receiving of knowledge of the interviewees? By asking directly to managers and peers to evaluate them? How? What kind of questions? Concerning self-evaluation (declared willingness to give/receive knowledge), what would be a fit way to ask? With a scale?
Any ideas, warnings, phrasing of questions, references of previous work may help very much in my reflection and design. Thank you.
