Complexity can quickly spiral when changes have to be made to products – especially in the case of mechatronic systems, as changes usually impact multiple specialist departments and are therefore an interdisciplinary issue. This makes a change management system that coordinates, synchronizes and brings together the disciplines and domains involved digitally all the more important. And this is exactly where the concept of global change management comes into play.
Changes occur for a wide variety of different reasons: new legal requirements, changes in market requirements, new scientific findings or feedback from customers. First of all, the system engineers develop alternative approaches for meeting the requirements. Once a suitable approach has been selected, a corresponding change request is made. Implementation of the change request involves different specialist departments such as systems engineering, mechanics, electrics/electronics (E/E), software, etc.
The challenge lies not only in the technical implementation but also in the coordination across disciplinary and domain boundaries, as each domain uses its own processes and tools. Information is often exchanged manually via Excel lists, e-mails, meetings or chat messages. This leads to media discontinuities, conflicting versions and decisions that are not transparent. Dependencies between partial changes often remain invisible, which makes managing the overall process difficult.
