Speaking assessment: business plan

I think the experience of last lesson was an important opportunity to learn the techniques of public speaking and improve our ability to present a plan. Our presentation was well organized and its structure was logical, but if I could try to present again a business plan, I would improve some aspects.
At first I would practice many times  in order to be more confident and have a more natural intonation. I didn't use enough signposting language so I would improve the use of formulas.
Then if I could present another plan I would add a bigger amount of information. Last lesson I forgot a part of my presentation, so I'd like to find a way to remember all the parts. For example I would use a sheet of paper with all the key words of my presentation.
