"Honestly, I have no problem filling in for tasks, especially when working with very small teams. However, I know what my role is, and that is to be the captain of the team. For example, if we have a significant deliverable and we're behind in the timeline because we only have so many people in the team, I'm happy to lend a hand if my bandwidth allows it. There are many ways to avoid this through risk management, but there are a lot of factors we can't predict. Team members or other resources could be missing or unavailable. Before I volunteer myself, though, I'll look for other ways to solve an issue first."
