Ideas for user-task dispatch UI/UX [on hold]

I have a UI/UX challenge, and i'd like to learn from others. I have to design a UI that will allow a professional to distribute/allocate/dispatch (you name it) a number of tasks to people.

So, here's the challenge:

  • There can be 400 tasks
  • There can be 40 people
  • Users have strongly expressed the need to "spot" tasks that need their attention (tasks with no allocation, inappropriate tasks for specifics persons)

How can I deal with all these factors in one design?
