We've switched to using Kanban at work.

I won't go into all of it, but one thing that has really helped is to have all the tasks in progress on a board where everyone can see them.

And only have one task in express lane and two non-express items at any time.

You haven't said whether the problem is too much work or competing priorities (or both). Whatever it is, this has helped me.
