A lot depends on how familiar you are with your topic and with the perspectives of the people you will be interviewing. When you do not have enough background in an area, then starting by interviewing some key informants can help you write an effective interview guide.

Then during the process of collecting data you have ways to increase the data validity as well. If you write me I can explained with more detailed. Good luk!
