I can’t say I’ve tried this application yet, but it looks like more bang than I’ve seen before at this prioce point (i.e. free). If you have a CIO that has just tasked you with saving a bundle of cash by replacing clunky commodity equipment with high-priced, name-brand, high-falutin’ enterprise goodies … this might be useful.
Anyway the term TCO is still present today but in a wider sense of course, though there is no common standard of how to get comparable TCO-figures unfortunately.
This is where the TCO-Tool may help: A well defined Cost-Model linked to a transparently modelled system (Base-Information or TCO-Objects) shall be the base for standardized and interpretable TCO-comparisons.
