Workshop for Heuristic and Exploratory Techniques (WHET)

At the 4th Workshop for Heuristic and Exploratory Techniques held here at the lab on July 7 and 8, 15 colleagues gathered to discuss boundary testing.

Aside from presentations from Keith Stobie, Scott Barber, James Bach, and Robert Sabourin to name just a few, there was a breakout session that consisted of two teams. One team’s mission was to find ways to discover boundaries. Here is the (unscrubbed) brainstorm from a team consisting of Karen Johnson, James Bach, Scott Barber, Dawn Haynes, Henrik Andersson, David Gilbert, and Michael Bolton.

It’s heuristic and some will need explanation from the idea owner (some day), but I wanted you to see the raw list that was assembled in just 30 minutes of discussion. What ideas do they trigger for you?
