Nancy Duarte has some interesting thoughts on the presentation landscape in corporations. In her words:
In every Q & A I get the same question: I”™m in a culture that thinks presentations are fine being hideous and ineffectual, what should I do? Here”™s a quick video I produced for you guys, with an accompanying PDF, that will hopefully help focus your strategy on high-stakes presentations (where there”™s the most pay-off). The Presentation Landscape has examples of which presentations to fight for ”“ and fight hard for ”“ and which ones are distracting skirmishes that you shouldn”™t bother with.
Here is the video. The source post and the pdf file can be found here.
