  text: Complexity of products and systems is increasing through digitalization, interdisciplinarity
    as well as high technology maturity and new business models. In consequence, new
    product development (NPD) projects need to manage and satisfy a large number of
    requirements from a broad range of stakeholders. Yet, NPD projects are often delayed
    due to requirement changes. In this paper, a new method for analyzing requirement
    change propagation is presented. The method is based on the assessment of requirement
    interrelations structured in a requirements structure matrix by a modified page-rank
    algorithm. By the method, a high number of strongly interrelated requirements
    can be analyzed in an efficient manner. Additionally, higher-level interrelations
    as well as the relative weights of requirements are also incorporated in the analysis.
    Hereby, an efficient holistic approach towards the analysis of requirement change
    propagation is proposed.
