Abstract

Change management of data processing paths by tentatively trying proposed alternative data processing path(s) without first giving up the existing processing path. If the alternative data processing path(s) does not give a more satisfactory result that the existing processing path, the existing processing path may be returned to. On the other hand, if any of the alternative processing path(s) do give a more satisfactory result, the alternative processing path may become permanent. The processing may be substantially automated.
