Robert Yin and Robert Stake are two major voices in the field of qualitative research, but they also have differing philosophical orientations. Yin’s work, with its post-positivist perspective, has been most commonly represented, with Stake’s constructivist approach less so. Many of the design decisions you make will be determined by the philosophical orientation—post-positivist or constructivist—you employ for your Doctoral Study. See if your philosophical orientation is more aligned with Yin or Stake, or perhaps a combination of both.
