These three have set in the left-hand-side of my Firefox tabs list for most of the year. I've come back to them again and again and will continue to do so :)

• Jeff Patton on Twelve emerging best practices for adding UX work to Agile development: "Let's recap. Two secrets to success in software development are: 1. Start sooner2. Build less software".
• Alan Cooper on Bringing sanity to swat-team design projects: "With increasing demand for design “"swat teams" to rescue fully developed but flawed software that is scheduled to ship within months or even weeks, the critical question becomes: how can you avoid getting caught up in the chaos that frequently permeates "crisis-mode" engagements?"
• A Scrum-Masters Checklist. Q1 of this year I need to print this out and track myself against it.
