20 Min Max presentation for assessment day

Hi Presentation Dr,
I have to give a 20 min (max) presentation in 4 days as part of an assessment day for technical graduate job with a software company. We could choose a subject of our own and I think I will focus on what I think are valuable core values for businesses today (relating specific IT issues). The subject is huge and I am having difficulty getting the presentation to flow.
Any suggestions how I can make sure i stand out for all the right reasons. I am nervous about presenting in front of all the other applicants too.

I like the topic. Rather than try to present on all the issues - just pick three. If you read the rule of three section - you will understand why.

The key is then to tell stories that help to illustrate the key points. Mke it as visual as you can.

Good luck!
