Story mapping is the most massively useful technique I know for visualising any sort of project or process. I’ve been using StoriesOnBoard for over 6 years now, and I couldn’t imagine a better, more user-friendly tool (and it kept improving all the time!) But not only is their product great, their customer service is truly top-notch. Immediate personal response, useful demo’s, actual hands on help in setting up new features... Chef’s kiss!
