At an industry event recently I had the opportunity to listen to a keynote by Janet Gregory, co-author of “Agile Testing” and “More Agile Testing”. During the talk, Janet asked the audience to pair up. One person stood facing the stage and projected slides, the other to face away. The person facing the slides was to tell their partner what they saw. They had 5 minutes to describe in every detail what was going on in the picture. The person facing away was told to visualize it. To try to remember and visualize every detail spoken to them.
When the clock ticked down and the five minutes were up. Janet asked the folks facing away from the image if they thought they had a good visualization of the image. Of course they did, they’d just heard 5 minutes worth of words detailing it.
Then she asked everyone to look at the image.
