That's so good I might just adopt it as a tag-line!
Note that it was a consulting group that put that monstrosity together.
Years ago when I had to brief senior officers there were no PowerPoint slides so you had to build transparency sets. You learned the reason and meaning of the term “brief” in briefing. Also, most senior officers would cut you off at the knees and send you packing if you became long-winded and detailed when you were not asked to be.
In the college classes I teach when I use PowerPoints they are there to place the main points in front of them as I’m lecturing and the lectures should be no longer than 15-20 minutes. I never got much out of long lectures and students today don’t either. Unfortunately, many students don’t take notes anymore anyway and will stare like they’re watching TV regardless of any slides or not.
