Aristotle wrote that “metaphor is the worst form of argument. He’s right. If you have something to show/prove, then do so precisely and in a way which is meaningful and useful to your target audience.
Recently the guys at Innovation of Risk posted an article on the use of infographics to analyse risk. I don’t know who coined the term “PowerPoint Engineering” but most infographics fit neatly into this category. Infographics can save presentation or they can sink it but mostly they are used to convey ill conceived and poorly thought out ideas which snowball into worse run projects. The best advice is to take these bath-tub moments (why do people think they have great ideas when they’re washing?) and run the analysis with an expert using an expert system. If you can’t do that then (a) you’re in the wrong department for having the idea in the first place, and (b) chances are that there is a tonne of minute but important detail you missed out.
Whilst I think that visual display of graphics is vital to achieve stakeholder buy-in, it is also clear that imprecise PPT-engineering masquerading as infographics is the worst form of management snake-oil there is. An erstwhile systems engineering mentor of mine used to say, “if you think they’re BS’ing you then ask them what the arrows mean”. 9 times out of 10 they won’t have a clue.
