Proaktives Management von Anforderungsänderungen in der Entwicklung komplexer technischer Systeme

Proactive management of requirement changes for the development of complex technical systems

Abstract

Requirement changes are a major source of inefficiencies in product development and increase the risk of project failure. Proactive management of requirement changes yields the potential to handle such changes efficiently. A systematic approach is required for proactive change management to assess and reduce the risk of a requirement change with appropriate effort in industrial application. Within the contribution at hand, a novel approach for Proactive Management of Requirement Changes (ProMaRC) is presented. It is developed in close collaboration with industry experts and validated based on five case studies. Automated dependency analysis based on artificial intelligence reduces the application effort compared to existing approaches. Semi-automated assessment and management of change likelihood and impact is performed using a modified PageRank algorithm. For the first time it includes all relevant influencing factors for risk analysis. The validation proofs that the ProMaRC approach achieves a convincing combination of practical application effort and completeness of analysis. This contribution opens up the research field of proactive change management for requirement changes which is currently almost unexploited and enables more efficient product development.
