Base Capacity(The amount of available time a resource has to work based on their resource base calendar. This is equivalent to the capacity of the position to which the resource is assigned. For example, a resource in a 70% part-time position has a Base Capacity of .7FTE. Not very useful for scheduling but of more value in determining the maximum capacity or cost of an organization)
Actual Capacity(The amount of time a resource has available to work at any given point in time. Actual Capacity is equal to Capacity minus resource calendar exceptions (e.g. offsite training, morale events, jury duty) and previously scheduled committed work (Project task assignments with type = committed). This is the most valuable measure for scheduling a resource)
