The whole question looks like that: Discuss the relation between epistemological starting points and theory on one side and method on the other, concerning two methods (or two methodological approaches within a larger methods field). How does the relation differ between the two methods (and what is similar)? Is a certain theory and/or epistemological starting point required for a certain method? If so which one(s), if not are there still some limitations regarding theory/epistemology depending on the method?
