Visual Thinking - What's Out of Play?

My colleagues and I were working on a team facilitation today. 

In order to frame the discussion, we asked what topics were open for debate, and which ones weren't.

I want to be clear that this wasn't censorship, or an attempt to avoid the 'elephant in the room'.

The 'out of play' topics are basically the 'No Whining' Zone, or the 'Dead Horse' zone - things that are constantly complained about, even though you know you can't change them.

As the group was generating the topics on Post-it Notes, I had the idea to represent the concept as a baseball field with 'fair balls' and 'foul balls'. It worked well, so Brent recreated it in a PowerPoint slide.

You could just as easily use a Football field (in bounds and out of bounds) with an international audience.
