Re: Ditto
From para 109 of the report: "The all-team briefing (paragraph 37) had 123 powerpoint slides, presented by a number of people, which covered health and safety, logistics, how the work should be carried out and the phasing of works on site. Some of the information was important, some less so, some inaccurate and some very poorly presented on the slides. " (my emphasis)
Normally "death by Powerpoint" is a metaphor. In this it could have been literal. How many people would remember anything after about slide #15? When I started having to do presentations at college we were still at the OHPs and transparancies stage. It certainly stops you waffling if you have to create slides by hand with OHP markers. A real challenge would be doing a presentation that gets all the important information across without using any slides.
