I don’t think most organizations have two decades to reach the highest level. As Jakob once suggested.
“The output of a UXMM assessment is a numeric score between 0 and 100. Higher scores indicate greater UX quality of the product. A minimum required benchmark score is also generated based on the context of the application. The actual score is compared with the benchmark score to determine if the application passes or fails that assessment level. The benchmark score is calculated through a benchmarking exercise based on a predefined questionnaire to be filled for the application that is being assessed.”
