Request an interview by phone or email

Know precisely what information you need

Seek references or other sources of information

Put the finishing touches, by thanking your interlocutor warmly for his expertise and his time.

Follow-up

Sometimes interviewees ask for the results of your interviews. Although it is not always possible to deliver all of the results, it is desirable to prepare a short summary and send it to participants, if possible.

Whether or not you can report the results, take the time to do a quick follow-up by email. A few days later, send a thank you note.

Politeness is your best tool for a rewarding interview and to guarantee reliable collaborators or sources of information.
