We all feel unproductive at times, and we can be sure that our bosses, clients, or co-workers feel we are being unproductive at times as well. And, because developer productivity is so hard to measure or talk about, it can feel frustrating to be in a situation where you are feeling or perceived to be unproductive. Rather than dwell on these feelings or postulate new broken ways to measure productivity, I want to talk about the reasons a developer might be unproductive. With some self-awareness, you can improve your situation.
