When research projects include telephone interviews, I always include a summary of each interview - one page, with all the questions and how that one person answered the questions. This interview-by-interview summary provides a great top-level view of the research results.
For additional insights, though, I also include a question-by-question summary of the interviews:
Clients appreaciate results formatted this way, because they don't have to look through all the interviews to get insights about each of their questions. It also helps me with the information analaysis, since it highlights any differences and/or similarities in responses, possible trends, and even new questions to ask.
Once you create a template, it's easy to copy and paste from the interview summaries - a small investment of time, with a big ROI. I'm happy to share my template - just contact me.
