The problem is that the slide contains talking points presented as bulletpoints. Without the author standing next to the slide to ELABORATE on his talking points, the reader is left with trying to decipher what is behind those cryptic talking points.
A much better way for the author to communicate his ideas is to hand out his report – with complete sentences and paragraphs – in PDF format so that the reader can understand it.
I wrote about this problem awhile back. Corporate America has replaced written reports that contain complete sentences with PowerPoint slides with cryptic bullet points. The readers are forced to read between the points!
Talking points without a talker is useless.
