Claim:
1. A computer program product for identifying software development teams causing operation incidents when changing and deploying code, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to: collect data regarding change requests and incident reports, wherein the data indicates only 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, irrespective of a content of the incident reports; generate a time series for the number of deployed change requests for each of the software development teams; generate a time series for the total number of incident reports created; perform Granger 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 determine 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, wherein causality is assumed to exist if 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, and wherein no causality is assumed to exist if the total number of incident reports created cannot be expressed in terms of the number of deployed change requests for any of the software development teams.
