Engineering changes are often classified as critical and lead to high costs. The reason for this is the high system complexity. To deal with high complexity, MBSE can be used as an approach. However, in order to be able to operate model-based engineering change management, suitable approaches are required. The Advanced Engineering Change Impact Approach - AECIA presents a holistic methodology for model-based change management by supporting change request validity checking, change propagation and change impact analysis, and change information communication in an agile development environment. In this publication, the methodology is extended to include a procedure for checking the validity of change requests, applied to a real change case using a machine tool as an example, and initially evaluated.
