In order to support companies in their approach for digital transformation, especially those that are not digitally native, in a targeted change process, the maturity model for digital transformation DX-MM is presented. The DX-MM was developed according to eight building blocks of digital transformation and assessed based on 20 interviews with representatives of leading manufacturing firms who evaluated the model. The findings suggest that the use of maturity models for digital transformation is needed and widespread in companies, but existing models lack a holistic approach as well as applicable concrete change steps and measures. The DX-MM attempts to close this gap as it allows organisations to analyse the status quo of digital transformation and supports in identifying specific and tangible steps and measurements for strategy-aligned digital transformation.
