The amount of time expended on PowerPoint, the Microsoft presentation program of computer-generated charts, graphs and bullet
points, has made it a running joke in the Pentagon and in Iraq and
Afghanistan
Rule of thumb I use in preparation of a graphic:
I will spend more time producing a presentation if:
a. The person being briefed is a VIP and the presentation is important (to me AND to him)
b. If it is a large audience where the large time-cost (to me) is but a small cost to them.
c. If the presentation will be used more than once.
If it is a small, one-off, presentation to a small group I might make do with a slide or 2. I also try for one slide per minute
of talk AND don't read out the slide.
That slide was certainly from chickens.
