I'm writing a thesis on development of business model for a wealth management based e-commerce business. In that I have one sub research question as Identifying Critical success factors for both the industry (Wealth Management as well as e-commerce). I am planning to do gather data via Interviews.
Therefore, I would like to know who should be approached in situations like this (Manager or Director or Executives)? Second, How I can get the interviewee to answer the critical success factors responsible for his/her industry?
Thanks in advance!
