First of all, TCO is important.
A ZDNet Tech Update article named TCO among the 7 biggest IT concerns for 2002 —
“the driving forces behind IT strategy for 2002--and the remainder of this decade.
These are the underlying themes that will cut across all of your major initiatives.
They are: vertical integration, mobility, open standards, total cost of ownership (TCO), availability, scalability, and security.”
According to
TCO is a calculation intended to arrive at, all things considered, the total effective cost of a purchase.
TCO overlays two aspects: the major categories of cost spent over several phases
during the life of the product/project under consideration.
For example, one strategy to lower TCO — Automated Self Diagnosis and Recovery —
can reduce costs (support time devoted to downtime incidents) and
maintain benefits (avoid loss of user productivity or reduce risk of financial loss).
Eric Stegman at the
Gartner Group
originated the term TCO Analysis,
a methodology to define all the ramifications of a major strategic
decision such as a commitment toward a certain tele- and data-communications
or Information Technology (IT) infrastructure. Typically, a TCO Assessment uncovers
hidden costs to arrive at the fully burdened costs.
TCO helps to avoid "apples vs. oranges" comparisons among alternatives
competing for the same limited budget dollars. For example, is buying a used ink-jet printer
really “cheaper” than buying a new brand-name laser when the cost of repair and cost of ink cartridges for various expected volume of work?
TCO should consider calculable financial numbers such as Return on Investment (ROI), NPV, IRR, and Payback Period,
TCO should also consider difficult-to-measure intangibles such as customer satisfaction, increased knowledge, and the organization's agility to compete.
The TCO has to be compared to the Total Benefits of Ownership (TBO)
to determine the true viability of a purchase.
Technology by itself doesn't do anything; value is achieved when technology is utilized as a strategic tool to support business objectives.
The ultimate net result of decisions should not just provide a financial advantage,
but improve the overall well-being of the organization and its constituents over the long term.
