  • Choose the right qualitative research method for the question at hand, understand when to combine methods, and know how qualitative research complements quantitative approaches.
  • Keep qualitative research trustworthy through grounded theory coding and Kvale's three lenses for objectivity.
  • Apply user research ethics, including informed consent, participant data safety, safeguards for vulnerable populations, and respect for participants' right to withdraw at any time.
