What is calculated by adding the cost of change, usage cost, and support cost for a period?

The correct choice is Total Cost of Ownership (TCO), which encompasses all costs associated with the purchase and continued use of an asset or solution over its entire lifecycle. This includes the initial purchase cost (if applicable), as well as the cost of change, usage costs, and support costs over a specified period.

In the context of TCO, the cost of change refers to expenses related to modifications or adjustments needed post-purchase, the usage cost includes the operational costs of utilizing the asset, and support costs encompass expenses for maintenance and assistance required throughout the asset's lifecycle. By aggregating these different cost components, TCO provides a comprehensive view that helps organizations understand the true financial impact of their investments beyond just the initial outlay.

Understanding TCO is crucial for effective strategic analysis, as it allows businesses to make better-informed decisions that align with their long-term financial goals. The other options, while relevant to financial analysis, do not accurately encompass the totality of these costs in the same manner as TCO does.
