While this approach is
best undertaken in the early stages of a project, focusing on and preparing for
the end product is especially crucial in the last few miles of a PhD journey.
So, if you are at the stage of focused writing, finalising thesis for
examination, or preparing for a viva voce (Latin for ‘by live voice'), answering
the following questions is the best
course of action to begin this process.

- Explain in your own words what you have done?
- Why did you undertake a PhD?
- What have you done that merits a PhD?
- What is original in your thesis?
- What's original about your work? What is your original contribution?
- Summarise your key findings.
- How would you describe your methodology, and why did you decide to use this?
- How do your findings relate to the literature?
- What are the contributions (to knowledge) of your thesis?

- What have you learned from the process of doing your PhD?
- Have you achieved your research aims?
- What is the contribution of your thesis to scholarly knowledge?
- Summarise your key findings

- Why have you chosen to organise your research into these stages/chapters?
- Is it possible to draw a general rule from your single observations?
- How have you evaluated your work?
- How do you know that your findings are correct?
- How do your findings relate to the critical literature in this field of studies?
- What have you done to be awarded a PhD?
Basic knowledge in areas related to the topic
- Who are the main stakeholders in this research? In which way will they be able to benefit from the results of your research?
- What have you done?
- Why have you done it?
- How did you do it?
- What have you found?
- What are the implications of these?
- Why did you do the research this way?
- Why not that way?
- What do we know now that we did not know before you started your PhD?
Questions about specific aspects (e.g., for topic X)
- How does your work relate to X?
- What do you know about the history of this particular aspect of your research?
- What is the current state of the art in X? (capabilities and limitations of existing systems)
- What are the recent major developments in this topic?
- Which are the most important papers concerning this aspect of your research?
- Why have you tackled this problem in this way?
- Where do current technologies fail such that you (could) make a contribution?

Research question(s)/ theory
- What was the original problem/research question?
- In which theoretical frame of reference were you able to place these research questions?
- How was the research question modified as a result of the literature question?
- Why was it changed?
- Specifically, which authors most influenced you thinking about your research question?
- In what way does your research question seek to establish a new theory, refute an old theory or develop an extension of the old theory?
Method(s) and defending methodology
- How would you describe your research methodology?
- Describe your methodological approach.

- What, on reflection, are the limitations, if any, of the approach you used in your fieldwork?
- Would your approach be as effective for other periods and places?
- What have you learned by carrying out your PhD?
- Why have you done it this way? You need to justify your approach - don't assume the examiners share your views.
- Why didn't you do it the way everyone else does it? This requires having done extensive reading?
- What are the alternatives to your approach?
- What do you gain by your approach?
- What would you gain by approach X?
- Looking back, what might you have done differently? This requires a thoughtful answer while defending what you did at the time.
- What would you do differently if you were starting now?
- What would you do differently today if you were to start again?
- How have you evaluated your work?
- How have you demonstrated that it works, and how well it performs?
- How have you demonstrated its usefulness for a specific application context?
- What do your results mean?
- How would your system cope with bigger examples? Does it scale up? This is especially important if you have only run your system on `toy' examples, and they think it has `learned its test-data'.
- How do you know that your algorithm/rules are correct?
- How could you improve your work?
- How do your contributions generalise?
- To what extent would they generalise to systems other than the one you've worked on?
- Under what circumstances would your approach be useable?
Analysis and results
- What analytical techniques/methods/tools did you use to help you understand the data you collected on your case study?
- Why did you choose these specific tools?
- What other tools did you consider, and why did you reject them?
- How would you describe your thesis?
- How did you arrive at your final thesis?
- In what way does it contribute to the theory, methodology, and practice?
- How do you regard your work from the point of view of the validity and reliability of the findings?
- What are the important lessons from your research in terms of personal development and from a contribution to X area?
Future dissemination and plans
- Outline where you think future development of your ideas could lead and how this might be done?
- What is the area in which you wish to be examined? (particularly difficult and important if your thesis fits into several areas, or has several aspects, or seems to fit into an area of its own as mine does).
- Which topics overlap with your area?
- Where will you publish your work - which journals? Think about which journals and conferences your research would best suit.
- How might the results of this research be converted into a practical application or outcome?
- What are the relative strengths and weaknesses of your research?
- What questions have you discovered in your research that still need to be explored by further work?

- How do you expect the research in your field to progress over the next few years?
- Where do you think your research will move in the future?
- What have you learned from undertaking this study?
- What are the wider applications of your findings – empirically and theoretically?
- What now?
- What is the best advice or recommendation can you give to the future candidate related to this topic?
- Can you now consider yourself as an expert in this field? Why?

suggest everyone to read and do.
Final note
There are considerably more resources
available now, so this list is really just a selection (just google viva PhD examination
or its variations for more). Also, this list is only a guide and by no way
comprehensive, so do not take these questions literally. Each viva, topic, field,
and examiners are unique, and examiners may ask differently. What's usually
the areas of concern are (i) research problems or issues and their rationale,
(ii) research questions, (iii) justifications for methods undertaken, and (iv) significance and contributions
of the study. Either way, preparation and practice will help decrease anxiety
and give us an idea of what to expect. It is best to overprepare rather than to
appear complacent. So, prepare, prepare, and prepare. Then, practice, practice, and practice again.
