Methods, systems, and computer-readable media are disclosed herein for a concurrent comparative tool for assessing multiple versions of a data model in a pre-deployment environment to ensure that any subsequently deployed version will perform than a current version of the data model. In aspects, the tool extracts observed and predictive data for various versions and comparatively evaluates the performance measures of each version. The performance measures can be validated across the versions to determine and select a leading version that has demonstrated improve technological performance and predictive accuracy. The leading version can be deployed.
