Since relations which consider the association of food with respect to space inhabitants and human inhabitants are considered, this research would require subject matter experts who have either worked on space research programs or food scientists who have worked on the topic of food relations that affect different functional sphere and career categories. Interviewing an institution with different levels of designated people departments might not be necessary here, however, interviews can be conducted with a few subject matter experts. Primarily, the interviewer can work with the institution to find out who would be the best subject matter expert who can help the researcher and who also would have availability at that time. The researcher would have to liaison with the institution first. The institution could be a space research agency like NASA or an affiliated agency working with them.The task is to collect primary data on subject matter experts. The interview will be initiated by first drawing up of data sources required to construct the interview. Background and detailed literature reviews have to be done. Once the questions are compiled, the liaison with the institutions will be contacted; and then based on the subject matter expert to be interviewed questions might have to be rearranged a bit. The interview schedule will be sent with the consent form to the subject matter expert in order to ensure that they are comfortable with the questions, and based on their feedback some more changes might be made. It is better to follow a structured interview pattern here rather than the semi structured or the unstructured as the questions are anyways once viewed by the participant before undertaking the interview.The interview would be recorded, but only transcript details will b made available in the data report. The report will include data in the appendices, and only the key concise data would be included here.
