See some before and after slide examples. These slide examples give you ideas on how to reduce the text, create more interesting images and show information graphically rather than always in bullet points. The before slide is mixed in between many slides discussing Access, the network, education, etc. There is no clear path for the audience to follow.
Time lines can be very useful to present the whole picture of the topics to be discussed in detail.
In PowerPoint this time line is an AutoShape, filled with a picture. The words are in a text box. That should not be the central focus. Added Value becomes the central focus on the slide and Section Four goes at the bottom of the slide. Use tables when comparing the past to the present, different products, vendor bids, etc.
