摘要: This article describes the emerging roles of systems engineering (SE) function in supporting enterprise management information-intensive organizations. “Enterprise Systems Engineering” (ESE) comprises three major or “levels” for successful and efficient development procurement large complex (SoS). While authors' experience focuses predominantly on government organizations acting as their own SoS integrators, ESE concept has generic applicability any organization, public private, seeking to attain competitive advantage through leveraging information technology resources systems. The processes tools described here have been developed successfully employed facilitate project investment decisions control.
