Software configuration management for a software system under development includes receiving a change to the software system under development from a first user, determining a merit score for the first user, wherein the merit score is calculated according to success of prior changes received from the first user, and comparing, using a processor, the merit score for the first user with a merit threshold for the software system under development. The change is accepted for inclusion in a build of the software system under development responsive to determining that the merit score for the first user complies with the merit threshold.
