The passage around this formula

A catalogue is not a triage plan. The ten differ enormously in how much damage accrues before anyone notices, and instrumentation effort should follow that rather than follow which failure is most interesting to write about. For a mode i with arrival rate λi\lambda_i , mean time to detection τi\tau_i , and cost per undetected instance ℓi\ell_i , the loss accrued before intervention is approximately
