"We developed an application using patterns and we thought that would help us hand over the application to the maintenance group.How did it work?
"So we sent them the code. They didn't understand. Hmm. OK, Let's try writing some documentation. So we write some documentation. They still didn't understand. OK, let's try giving them some training. So we trained them. Better, but they still didn't get it. Hmm. What now?
"Someone in my group came up with the idea of doing a play, to explain the roles. So we all put on silly hats and acted out the architecture. 'I am the dispatcher and forward requests to interested parties.' 'I am a user agent, I submit requests on behalf of a user' etc. Lacking a better idea, we tried it!"
The other team reported, "We didn't like it -- we felt silly wearing the hats. And why you needed to put on a play to explain something so simple as your server architecture, I do not understand".
Kind of new twist on learning by doing... and we all know that is terrific way to learn. Could be a new application for youtube...
