In Defense of PowerPoint
PowerPoint on Trial
PowerPoint has a bad rep.
PowerPoint... is evil.
Edward Tufte, Author of The Cognitive Style of PowerPoint![]()
PowerPoint makes us stupid.
General James N. Mattis, U.S. Marine Corp.![]()
PowerPoint could be the most powerful tool on your computer. But it’s not.
Countless innovations fail because their champions use PowerPoint the way Microsoft wants them to, instead of the right way.
Seth Godin, Best-selling Author![]()
'Death by PowerPoint' they cry, through the halls of America's largest corporations.
How does one defend the indefensible?
Here is the plan:
Our bad PowerPoint presentation failures are not the fault of poor, innocent PowerPoint. Instead, our business presentations fail for three fundamental reasons (each user error):
- Using PowerPoint as if it was a process (it is a tool)
- Mistakenly preparing for speeches, not 'sit-down' style business presentation updates
- Focusing our preparation on style, not substance
The Case for the Prosecution
How do they hate thee?
Let me count the ways...
Witness A: Edward Tufte
Edward Tufte identifies key weaknesses of PowerPoint:
- Cognitive style. Presenter-focused, not content or audience focused.
- Low resolution. Little info per slide - so more slides are needed. Data graphics are weak: average of 12 numbers per graphic.
- Bullets. Bullet lists can show only 3 logical flows: sequence; priority; or membership. Multivariate models with feedback and simultaneity can't be listed. This encourages lazy thinking, generic ideas and ignores critical relationships and assumptions.
In fact Tuft implicates PowerPoint in the Columbia Space Shuttle disaster.
Witness B: Peter Norvig
Additional witnesses have piled on to point out the limitations of:
- Overly simplistic business charts
- A poor outliner which drives ideas to be arranged in unnecessarily deep hierarchies
- Poor typography and chart layout tools
- Clip art (!)
- Overly rigid enforcement of a linear progression through a narrative
- Default templates that are poorly designed and result in uninspired presentations
Bad PowerPoint is hated.
