Use cases

• Platform devices - As a platform device administrator, I'd like to be able to view my device inventory by location.
  • At this time, I only need to know the number of devices per location.
  • In the future, I may want to know the number of devices by type or some other categorization such as licensed.
  • I do not foresee the need to view my devices by status.
