Hello,
I hope you will find this in good health, I am in a situation of How and Why related research and have opted a single case study to find the answers.
1. I am not developing any new theory, and I have a constraint of time for the interviews.
2. The firm under scope does not have any literature available on it.
I do not want to waste time on introductory questions about the firm and the person, and I have an option to ask the interview respondents fill a questionnaire about the firm and themselves.
The research is qualitative, is it suitable for deductive approach here?
Can I use questionnaire as a method?
