I like the do-not-overload your slides advise and noticed tremendous improvements in focus and "aliveness" in my presentation but I was wondering if anyone from a more traditional finance or consulting perspective could weight in on that issue. For example a friend of mine works on conventional M&A projects - with very crammed Powerpoint slides full of facts and figures. I have seen similarly crammed slides from the big consulting corporations. Now I was arguing for a Tufte approach, i.e. making handouts instead, but he rejected the suggestion as he is only one of the younger team members and the therefore associated problems with breaking the "we have always done it this way" paradigm. I am still somewhat pondering about this issue and I am not quite sure if having really packed slides can not actually become beneficiary in some occasions - meaning a hitting-them-over-the-head-with-data approach where it is core to produce some "evidence" and "analytical" approaches. I have found a similar mindset among some academics for constructing the viability of their research questions, methods, results in order to succeed in the peer-reviewed process. I would love to hear some opinions by those working in conventional blue chip companies how they view this slide/presentation issue.
