• TCO can bring out so-called "hidden" costs of ownership.
In this example, management chose to include all the important costs caused by system acquisition, including the labor costs of people who use or support the systems.
When deciding whether or not to acquire a new system, it is easy to become distracted by hardware and software cost, but in fact the "People" costs that come with the system are 68.8% of the very large TCO. How well these people are trained, employed, and managed will be far more important in determining actual cost of ownership than other factors, such as the choice of HW or SW vendor.
