Microsoft PowerPoints Are Terrible for Engineers
Engineers over use PowerPoints to make technical presentations, and the results can be disastrous. So says Edward Tufte, professor emeritus at Yale University, who is an expert on statistical evidence and analytical design. Example: NASA executives had a fatal misunderstanding of the potential danger to the space shuttle Columbia because of overly simplistic PowerPoint presentations made by Boeing engineers. That may seem hard to believe, but Tufte made a convincing case when he spoke at a seminar in Boston yesterday. His viewpoint was validated by the Columbia Accident Investigation Board in a report issued in 2003. “The board views the endemic use of PowerPoint briefing slides instead of technical papers as an illustration of the problematic methods of technical communications at NASA,” the board wrote.
Why are PowerPoints a problem for technical communication? 1) They oversimplify complex technical data, 2) They tend to reflect the biases of the presenter, and 3) Information becomes even more filtered as PowerPoints are summarized and moved up a bureaucratic hierarchy. Tufte puts it simply: “Serious problems require a serious tool: written reports.”
A separate NASA task force investigating escalating communications problems in the agency made this damning statement: “It appears that many young engineers do not understand the need for, or know how to prepare, formal engineering documents such as reports, white papers, or analyses.”
WDREEVE commented:
You\’re blaming the tool. It\’s clear that graduates are too lazy to do real analysis and resort to oversimplification. The fact they use PowerPoint has nothing do with it.
Bret commented:
Is there a link to the disasterous Power Point slides? I would like to see them.
There is always too much data, but yet the major and salient points always need to be brought out. I recall a Feynman demonstration with ice water and an O-Ring after the disaster that had only one bullet point. But it was the important one.

management want for good looking presentation, technical paper is too hard for them already.
Dan McCarthy commented:
Hi, Doug.
Yes, Dr.Tufte explains a lot in a short 8 hours; he is the most riveting speaker that I\’ve ever heard. The New York Times called him \”The Leonardo da Vinci of Data\”.
Stan Kulikowski commented:
Mr. Tufte has an excellent point, but I think that blaming PowerPoint is the wrong conclusion. His three points all reflect issues with the author of a presentation rather than the software package. Engineers need to think about how to present data and consider the audience receiving this information. If the audience is a group of engineers, why \”dumb down\” the information. Present the data and let the data speak.
Mr. Tufte\’s data presentation seminars are an excellent refresher for data presentation. He has a wealth of information on how to present data in a meaningful way. I would recommend anyone making presentations to take the time to attend one of the seminars.
Jonathan Williams commented:
That\’s not a problem with the tool (Powerpoint). That\’s a problem with the engineer using the tool. If the tool doesn\’t support the end use, find a tool that does. Powerpoint doesn\’t oversimplify the complex data, the AUTHOR does it. Your headline should read, \”Sloppy Engineering is Bad\”.
epukerob commented:
Talk about shooting the messenger! I have attended Tufte\’s seminars, and thet are great! But MS PPT is nothing but a communication tool; garbage in, garbage out. Rather, why not promote, i.e. TEACH o\’ professor emeritus a \’Tufte-approved\’ method/use of the tool? executives will ALWAYS need briefs and summarized information… Perhaps if the \’really good\’ report is written first, followed by the ppt brief derived therefrom?
Sterling commented:
Power Point is just a tool - and it can be a very useful one when used properly. The problem is not in the tool, but in how and when it is used. The real problem lies with the engineers (and sometimes their management, since they may oftimes mandate the wrong approach to communication) and whether or not they are putting forth the appropriate effort to ensure that the proper communication is achieved.
This should not be a question of \”new\” engineer vs. \”old\” engineer either. Communication is a critical and inherent part of the engineering responsibility. It is up to each of us to learn to do it correctly.
Jim commented:
It definitely makes more sense to write a paper, then brief the paper with the presentation. But when management focus is on the presentation, that comes first and the paper never gets done.

First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
