In order to keep track of how many staff members are still available or already fully booked, the current staff capacity must be callable at any time. This can be achieved by using either the Inventory^M or the Shift and Staff Planning^M module.

1. Open the Staff role and activate  Shifts in the toolbar. A new  Capacity tab will appear in the side navigation.
2. Go to the new  Capacity tab to input staff capacity.
3. Click on  Add to add or subtract numbers.
4. The Valid from date and the count (Plus_Minus) will appear in an input window for the inventory change. Enter additions as positive numbers, reductions as negative numbers.
5. Enter the number of guests who can take on this staff role.
   Note: This field is not updated automatically when a staff member is assigned to a staff role..
6. Stay on the  Capacity tab. If you want to be notified of insufficient human resources in good time, enable an alert and set the number of lead days in the Conflict alert (days before deployment) field.
7.  Save your input by clicking on the icon in the top left-hand corner of the input window.
