If you are rostering an inbound team then you should have run the forecast.
For an outbound team you can decided with your want to setup Staff Requirements as they are purely optional.
Staff requirements provide you with a guide for how many staff you need at each time of the day.
One feature that is useful even for outbound teams is that the requirements understand 'breaks'. Read more below to see why this is useful.
In either case you may need to alter the staff requirements.
To edit Staff Requirements click the 'Edit Requirements' checkbox.
You can now edit the Requirements by click at the top of any bar and dragging it up or down.
