Ali,

This is great. I would suggest that there are more levels like:

Organization Names
Title
Location, Floor, Module, Cube/Office/Equipment room/Printing/copier room (if located in an employees office)
Responsible Support person
Lease start date or purchase date
Lease end date or decommission date
Asset depreciation/Assets depreciation
Asset Replacement option to replace current imputed assets
Purchasing Agent/Contract owner/Contract decision maker
Graphs by equipment type with contract, lease duration, lease end dates, Asset depreciation, Asset replacement, etc.
