Are you defending a thesis (MA) or dissertation (PhD)?
Has your supervisor/committee chair confirmed that your thesis or dissertation is ready to be defended? 
Have all of your committee members been distributed a copy of your thesis or dissertation for review?
Have you registered for USF's Electronic Thesis & Dissertation process? If not, use the following link to do so:

https://www.usf.edu/graduate-studies/students/electronic-thesis-dissertation/etd-process-overview.aspx
Will your defense take place in person at USF or virtually over Microsoft Teams?
For PhD students only: Is your outside committee member going to serve as the dissertation defense's external chair? (the answer to this question is typically yes, unless your outside committee member is unable to attend your dissertation defense. If your outside committee member cannot attend the defense, you will need to find another faculty member from outside SIGS to attend the defense and serve as external chair. This person acts as your advocate in the defense, and doesn't need to read your dissertation to fulfill this function).
