Individualism/collectivism is the most important value, so pay particular attention to that one. However, you will also need to discuss all the other values or cultural elements examined in the text and in the article. Be as thorough, detailed, and organized as possible.
In your analysis, also address this question: what impact could these differences have on intercultural communication and understanding? For example, if you come from a low power distance culture, and you have an employee or student who is from a high power distance culture, will they feel comfortable coming to you with complaints or disagreements? Avoid email or phone interviews, they don’t generate enough material for the paper. Prefer face-to-face or Skype interviews. Email and phone interviews lack details and interpretation of nonverbal behavior. Your paper will appear “shallow”. During the interview, probe, probe, probe!! Avoid the “difficult” interviewee (one that gives only yes-no responses). You want them to talk to give you enough material for the paper. In addition to your questions, add a demographic section at the beginning of the interview: gender, age, occupation, major, how long in the US, country of origin.
