PhD PowerPoint Presentation for Defence

Hello everyone.

I am a PhD student in computer science in Germany. I am two weeks away from my defence, and I am struggling with what to include and what not to include in my PowerPoint presentation.

To clarify what I want to ask, what should the outlines be?

For instance, various resources suggest that students must include a slide of their contribution, while others do not.

Therefore, I would appreciate any and all supportive comments which will help me prepare a fruitful defence presentation.

Thanks in Advance.
