I am conducting a multiperspective interviews on cultural competence in healthcare institutions (management level). Some interviews are individual, but in some institutions, they expressed the wish to conduct the joint interviews (e.g. medical director, nursing director, HR director)- which I could not decline. Is it aceptable to analyze all the data jointly (treating each respondent as a single unit)? Any references or suggestions? I want to add that I am investigating their views, beleifs and attitudes towards the topic, and I was careful that all of them had a chance to express them. Thank you kindly.
