In our company we have a vivid agile community. After becoming a recognized practitioner I recently suggested to present PA at one of our regular get2gethers. Luckily I got enough votes to be qualified to hold a speech;-) I decided to do it in a very focussed way: I used 5 flip charts and developed the idea of PA during 10 minutes (see attached files) in front of around 30 colleagues. During the following 10 minutes I answered numerous questions from the interested audience. Hopefully this will encourage you to share your experiences too with your environement!
