While reading Scott Berkun’s defence of PowerPoint, a phrase came to mind “A bad workman will always blame his tools”.
I’ve sat through so many bad presentations where the first thing the speaker does is to apologise for the “Death By PowerPoint”, and the converse, which doesn’t happen that often, is a good presentation where the speaker uses the tool as an aid to draw your attention, like it was designed to do.
I agree with Scott, YOU need to take responsibility for the work you deliver, you should never blame a tool for your shortcomings.
