I'm a UX designer embedded in a semi-agile team (we have standups and retrospectives, but don't do everything to the letter). I find I do a variety of things, like logging bugs and helping with customer support, that don't fall under the typical job description of a designer. Sometimes, I feel like this helps me learn more about the product and the user base. Other times, I feel like it's a waste of time that I could be using to do research or design (i.e. the tasks that I was hired for).
If any of you work closely with or are embedded in a development team, how do you contribute to the team? What do you do that helps you mesh with the team better while still leaving plenty of time for design?
