By default, this privilege is contained by two roles: build_mgr and ccm_admin. Only a user in the ccm_admin role can edit this privilege. Each site can add or remove this privilege from any role.
A process rules manager can create or edit a process rule. However, if a build manager tries to modify a process rule that would require modification of a project for which the build manager does not have permission to modify, the operation fails. In addition, a build manager cannot delete a process rule that is in use in the working project of any developer. Only a user in the ccm_admin role can delete a process rule.
