Tell one clear story from problem to result

A good project presentation is a story with a simple arc:

1. The problem: who has it and why it matters (one slide).
2. What exists and the gap: briefly (one slide).
3. What you built: objectives, architecture, key decisions.
4. The demo: the system solving the problem.
5. Evidence: testing and results against objectives.
6. What you learned: limitations and future work.

The University of Sheffield's guide for undergraduate project vivas suggests a similar overview: aims, why the work matters, the approach at a broad level, your personal contribution in a group, and what you achieved. Keep week-by-week history out of it; examiners want to understand the result, not every step.
