Has my view about my topic changed in light of my research?
Do I need to revise my research question knowing what I know now (broaden or narrow my topic, or start over)?
Can I answer my topic and supporting questions with the information I have collected?
After reviewing your notes and answering the above questions, you may not end up writing the paper your originally intended. Your focus may have changed after you have discovered new information.
If you change your research question, come up with further questions and topics to research in order to answer your question
