Mean time to resolve (MTTR) isn’t a viable metric for measuring the reliability or security of complex software systems and should be replaced by other, more trustworthy options. That’s according to a new report from Verica which argued that the use of MTTR to gauge software network failures and outages is not appropriate, partly due to the distribution of duration data and because failures in such systems don’t arrive uniformly over time. Site reliability engineering (SRE) teams and others in similar roles should therefore retire MTTR as a key metric, instead looking to other strategies including service level objectives (SLOs) and post-incident data review, the report stated.
