Let’s say that you’re making a PowerPoint presentation on improving businesses.

Let’s further say that you want to illustrate how the members of your business’s management team must work together. You decide to use a picture of gears to show how the team interlocks and turns as one.

You go to iStockPhoto and grab this picture:

If you then show this presentation to a bunch of scientists and engineers, don’t be surprised if they point out that these gears won’t turn.

iStockPhoto has a lot of other gears that you can choose from. Please don’t pick the photo that looks like it belongs on There, I Fixed It.
