Why is MTBF important for budgeting and maintenance planning?

Why is MTBF important for budgeting and maintenance planning?

• A. It ensures exact replacement timings for every device.
• B. It determines the resale value of hardware.
• C. It allows technicians to budget for repairs or replacements based on average failure rates.
• D. It measures network throughput.

Answer: (C)

Mean Time Between Failures is the average interval between failures for equipment operating under normal conditions. It’s a probabilistic measure, not a promise of exact timing, so it helps you plan rather than guarantee when a component will fail. This statistic lets you forecast how often failures will occur in a given period, which in turn supports budgeting for repairs or replacements, stocking spare parts, and scheduling maintenance labor. For example, if a device runs 2,000 hours per year and has an MTBF of 1,000 hours, you’d expect about two failures per year per device; multiply by how many devices you have to estimate total spares and maintenance workload. It’s not about exact replacement timings, resale value, or network throughput.
