Initial hardware and software

Training Support Upgrading Maintenance Hardware Software extras Communications networks

TCO estimated at

four times

the hardware costs!

January 23, 2003 28

TCO: Reduce the TCO

Limited Options – standardize the ordering process including hardware, software, and options

Helpful software – counts computers and determines their components and installed software in a networked environment

Hardware and software upgrades – insure there is justification for an upgrade
