A method for identifying software development teams causing operation incidents when changing and deploying code, the method comprising the steps of: collecting data regarding i) a number of deployed change requests for each of the software development teams and ii) a total number of incident reports created for all of the software development teams; generating a time series for the number of deployed change requests for each of the software development teams; generating a time series for the total number of incident reports created; performing causality testing between the time series for the number of deployed change requests for each of the software development teams and the time series for the total number of incident reports created; and automatically identifying particular software development teams causing the operation incidents when changing and deploying code using only the number of deployed change requests for each of the software development teams and the total number of incident reports created, irrespective of a content of the incident reports, by determining whether the total number of incident reports created can be expressed in terms of the number of deployed change requests for any of the software development teams.
