Consider some of the following questions ahead of your viva to capture thoughts on the difference your work makes:
- What does your thesis add to what was known before?
- How does your work change previous perspectives in your research area?
- What could someone do in the future with your conclusions? How could they develop your ideas?
- What is new in your field as a result of your work?
One question that always applies to a PhD candidate is to consider how am I different now, compared to when I started my PhD?
Because you must be different.
You’ve learned. You’ve grown. You’ve developed yourself.
Remember that the difference you’ve created through your work is a result of the difference you’ve made in yourself.
