Network Infrastructure Specification and Costs
Network Infrastructure is calculated as the cost of equipping one computer, whether it be a
workstation or a server, with a connection point on a port or a switch, appropriate cabling
and a wall socket, as per current industry bestpractice.
Research has shown this turns out
to be approximately $100 per computer.
Therefore, network infrastructure is calculated as the number of computers multiplied by
$100.
Total Cost of Network Infrastructure 259 x $100 = $25,900.00
Staff Salary Specifications and Costs
Staff for both our Windows platform model and our Linux/Open Source environment were

itemised three core staff members for our example organisation. We require a Senior
systems administrator and coordinator,
reporting to our example firm's executive
management. We also require a midlevel
generalist, and a junior helpdesk
support
staffer. Ancillary or specialist technical services will be provided by external consultants.
