Seriously, powerpoint is a tool, but like any tool, use it too much and you begin to rely on it to do things it was not created to do.
For example, I have an awesome set of pliers. I can use them to pull nails out, tighten/loosen stubborn bolts/screws, pretty much anything...almost.
The other day I had to pound a nail into the wall, and I had my pliers in my pocket, so I whipped them out, and using the flat side started pounding away. I ended up missing and hitting my wall and putting a plier shaped indentation in the wall. I also left some nasty little marks on the side of the pliers.
Now take that metaphor and apply it to Powerpoint. I can use it to show people a slideshow. I am trying to sell a piece of software, I put its 10 best points on a few slides with some images and charts and voila, a sales presentation. The customer will still want to see the product. No matter how good the presentation, it is, in the end, just a snapshot (even with animations,) not the real thing.
Now imagine generals using powerpoint to run a war, I can throw 10 points of the war on a powerpoint, and give a concise briefing, but there are a few clear shortcomings:
1. Inevitably the ideas presented are limited to those that can be reduced to bullet points.
2. If presenting to a figure of authority, the incentive is usually to present the positive aspects
3. Combine #1 with #2 and you get a couple of things, a mess in the toilet (lol @ toilet humor) and a bunch of decision makers, making decisions based on bullet points rather than substantive reports. When the decision makers don’t have all the information, they make bad decisions.
Power point has a time and place, but war time briefings should use powerpoint only as short supplements to the real information.
Now lets return to the office world and do a quick revenue calculation. My company (that shall remain unnamed) does an earnings call every quarter and a longer one at the end of the year. Each earnings call is accompanied by several internal and external meetings to go over the numbers/accomplishments etc... There are usually separate presentations by the CEO, CFO and COO , the three highest paid guys in the company and each presentation is about 30 minutes long and has 15 powerpoint slides.
