Here are the key strengths and weaknesses of the research methods: - Product research provided real examples to analyze but lacked context and only showed a limited perspective. - The online questionnaire was efficiently distributed but had a low response rate, limiting insights. It also relied on self-reported data. - Interviews allowed for follow up questions but only captured a small sample size. Responses may have been influenced by the interviewer. Overall, triangulating multiple methods helped overcome some individual limitations but also resulted in large amounts of unsorted data. Focusing the research questions and analyzing responses systematically could have strengthened the findings. Further primary research may be needed to fill any gaps.
