I am presently doing my master's dissertation. I aim to identify a perception gap between brand positioning and brand image through a study of brand storytelling. It's a qualitative study (interviews) and I am planning to analyse the data through thematic analysis. I want to know whether a study of this nature falls under grounded theory in terms of methodology. Can I use TA for data analysing while following grounded theory as the methodology? (if not, which methodology will be more apt for this study?). Thank you.
