AbstractThe integration of systems to create a stable, robustsystem of systemsposes challenges to systems engineering management when the individual systems already exist, are numerous and rapidly evolving. The Dynamic Object Oriented Requirements System (DOORSTM) introduces advanced object‐oriented techniques to manage the complexity of large numbers of inter‐linked requirements. DOORS provides an easy‐to‐use, online environment. Different on‐line views of the project status are available in both text and hierarchical graphical formats by filtering and sorting on the attributes of the objects. This object‐oriented approach to requirements management is extended to provide agroupwaresystems engineering management environment in support of the U.S. Army's program todigitizethe battlefield of the future. The Army's intent is to improve their comparative advantage in combat effectiveness over that of potential adversaries. The magnitude and complexity of the effort to manage the project compared to classical requirements management methodologies and tools ar
