Experience mapping
I create experience maps as a way of modelling how users interact with a product. Usually these will start with a defined persona. I use quantative data that can be taken for example from traffic reports or user surveys. I also use qualitative data taken from users during testing or focus groups to undertsand their motivations, pain points and goals. The resultant journey makes a great basis for a strategy for understanding how opportunities can be exploited, and how the various touchpoints can be harmonised to provde a better user experience.

Story boarding
Another method I use to understand the real world of users is through storyboards. I find that images and stories can be a more powerful way of showing what is going on in the world of users and how we can make their lives better. Below are a few examples of storyboards I have created.

Persona creation
There is a maxim in UX, "it all starts with knowing the user". For almost every project I have worked on, I have used personas and, where none existed I have taken steps to create them. I gain insights from talking to users during focus groups or testing to large scale ethnographics studies.
More recently I have found myself shifting towards the Job To Be Done paradigm, particularly in those projects where it was necessary to challenge the perceived business objectives against those of the user.
