In the TCO example, the time period used was five years.

• A. True
• B. False
• C. It depends
• D. It was ten years

Answer: (A)

In a TCO analysis, the key idea is choosing a time horizon over which all costs are totaled. In this example, the horizon is five years. Five years is a practical window because it typically covers the major lifecycle costs—initial purchase and deployment, ongoing maintenance and support, software licenses, and the likely refresh or replacement cycle—without venturing into highly uncertain long-term costs. Since the example indeed uses five years, the statement is accurate. If a different horizon were used, the total costs and conclusions could change, but for this scenario five years is the period represented.
