CEOs should not spend time writing their own PowerPoint presentations and as a result, most of them did not get around learning how to use the software. That is a shame. I recommend that every CEO should familiarize herself with some basics: editing text,  moving/deleting/pasting slides and inserting big comment boxes electronically on slides. It can be picked up in a 2 hour training and will make life so much easier for them when they fine tune the final 1% of the deck before going on stage.
