People over process. The first agile value is probabaly the most challenging for analysts. It's the thing that analysts do, understanding processes and designing new processes. The way they work is typically driven by process.
I probabaly have more discussions with analysts about ways of working more than any other agile team member.
I first worked with Mark on the LASER project at learndirect, and we then worked together at South Yorkshire Police where I started to get the team to work in an agile way. Together we came up with a neat way of describing the user journey using annotated wireframes which worked exceptionally well.
