I liked the graphing approach to reporting which to me is simple yet effective; a very immediate way to communicate what happened.
The tutorial pulls in several user experience research techniques - usability testing, personas and diary studies - and explains how they can be used to better understand the experiences your customer goes through. I like the focus on the bigger picture, rather than just engagement with your business or website.
