Thoroughly recommend this activity to those who can make it.
Last year I presented to the group ans was quite impressed by their questions and recommendations.
It was enlightening for me to have a number of groups looking at my issues from different perspectives and opening my eyes to assumptions I had made.
Truth be tols I have yet to get through all of the documentation and recommended reading the students provided but it is on my to-do list.
If you have the opportunty, give it a go.
