Abstract Shorter product innovation cycles, high variant products, and demand fluctuation, as well as equipment life cycles and technology life cycles force manufacturing companies to regularly change their manufacturing system. In order to address this challenge, an efficient and structured change management is required. As change causes and factory elements are connected via a complex network of relations and flows, an essential step in change management is the evaluation of considered adjustments with regard to their effects on the current production system. Depending on the context of the application, change impact analysis must process specific inputs and deliver different results. Current approaches, however, each focus only on selected aspects of the versatility of change effects. To address this challenge, this paper presents a modular approach for the individual design of change impact analysis.

1 Introduction Manufacturing systems are facing a high number of company external as well as company internal influence factors [59]. In case an altered requirement cannot be addressed with the available flexibility of the current system, changes or reconfigurations are required [20, 54].

developments towards shorter innovation and product life cycles [28, 48] as well as customer individualization and higher product complexity [44, 50], the need for change occurs more and more often. In order to cope with the increasing frequency of changes, efficient change management processes are considered as crucial [26]. A prerequisite for successful change implementation within expected time and budget as well as for economical evaluation and decision-making is knowledge about all possible change impacts and necessary activities [40]. Therefore, approaches for change impact analysis (CIA) support this holistic assessment. However, the available methods only address specific aspects of the versatility of possible change impacts and are therefore only usable in a limited context. For a broad applicability in industry, this paper presents a modular approach, which can be individually designed according to the objective and starting situation of the analysis. In order to specify the scope of
