1. A computer implemented method for management of information technology component software levels, the method comprising executing steps on a processing unit for: in response to a determination of an incompatible software level of a first component of a plurality of components in an information technology infrastructure, determining an outage count score for the incompatible software level as a function of a historic count of outages caused by a similar incompatible software level found in a knowledge base history; generating a normalized historical affinity risk score for the determined incompatible software level as a function of combining the determined outage count score with an average outage severity score that is assigned to the determined incompatible software level as a function of a level of severity of an actual historic failure of the first component within the infrastructure; and prioritizing correction of the determined incompatible software level based on a value of the normalized historical environment risk level score relative to values of other normalized historical risk level scores of other incompatible software levels that are determined within the information technology infrastructure.
