The estimated Annualized Failure Rate (AFR) is based on parts count and the failure rates of
those parts in similar products. The AFR is estimated from the sum of the failure rates of the
components assemblies. A key assumption is that AFR is constant beyond the early life of the
product and before long-term wear out.. Mean Time Between Failures (MTBF) is the
reciprocal of the AFR.
