Update annually to accommodate strategic and budget plans.
IT Architecture Describes:
• The way Work activities are organized and the Locations where the work is
carried out
• The Information Sets/Databases needed to perform the work
• The Applications/Software that capture and manipulate the information sets
• The Technology Infrastructure (hardware, network and communications)
needed to run the applications
