"Managing multiple campaigns is a regular part of my job at 123 company. I don't think there's a hard-and-fast number to say 'too many,' but projects often vary in terms of how much resources they take up versus their impact on revenue. For example, I could be assigned a project scheduled to run for six months and requires just a two-person team. That would probably take up an hour of my day on average. However, if I'm managing a high-value project that's due in two months, I may need to dedicate a huge chunk of my time daily toward it. What I usually do is keep my superiors informed of the progress of each campaign so that they have a better understanding of how I use my time. If needed, I should be able to delegate tasks to other team members and focus on the overall success of each campaign."
