For me, going above and beyond the call of duty is really about going all out to get a job done properly. For example, I once worked on a large team project where I could tell that one of my colleagues was struggling with his task. To some extent, my work was dependent on his and it's probable that had he delivered late, I may have delivered late as well. I approached him discreetly over lunch and offered to stay late and help him out. He couldn't thank me enough. We worked through the night and he was able to deliver on time and so was I.
