Techniques for quantitative converged network assessment are described. Performance information, associated with network infrastructure elements and application or service elements of a computer network, is received. One or more key performance indicators of a reference network architecture are compared with at least a portion of the performance information. A plurality of first scores is determined based on the comparison of the one or more key performance indicators and at least a portion of the performance information. Based on the plurality of first scores, a single second score is determined that indicates a converged state of the computer network with respect to the reference network architecture.
