Fix Rate: The Metric That Replaces Finding Count Certificate

Awarded for completing Fix Rate: The Metric That Replaces Finding Count and passing its exam, demonstrating the ability to state what an open finding count does and does not measure; to define fix rate precisely by period, by cohort and by severity band and to decide how closures that are not fixes are treated; to compute and decompose a fix rate so that movement caused by inflow is separated from movement caused by performance; to report remediation time as a distribution and to set service levels on percentiles; to use escape rate, recurrence, suppression rate and the queue's age profile as counterpart measures that close the routes to gaming; to recognise the nine routes and their detections; to judge when per team reporting is legitimate and when it has become a stick; to describe a healthy programme without reference to any external benchmark; and to present a metric that fell for a good reason without losing the improvement that caused it.
