Tracking other people's work.
As manager of an audit practice, I have to not only manage my list of tasks, but also make sure my employees have work and are getting things done in a timely manner. They are often responsible for completing an entire project on their own and I supervise as needed and review the work. My source of stress isn't that I can't remember to buy batteries at the store, but that there are all these various jobs floating around that I am responsible for, yet are not actually doing the work.
Anyone have a similar situation or some suggestions. I know it would be great if everyone at the office used GTD, but that just isn't going to happen.
