Definition of Enterprise Architecture-centric Models for the Systems Engineer

摘要

Enterprise Architecture definition provides guidance to the systems engineer so that the enterprise system better reflects the needs of the customer. With the current systems engineering approach, the systems engineer can allocate requirements to systems without considering enterprise-wide considerations. The architecture-centric approach for system design provides enterprise-wide information for systems engineers, who can utilize it to affect systems design. This paper describes Enterprise Architecture and related concepts, and explores the state of the art of Enterprise Architecture and Enterprise Architecture frameworks. The Zachman Framework is used as the basis for creating models of the architecture. This paper proposes a bridging concept to define the models for the architectural perspectives. The bridging process provides a traceable methodology for developing architectural models of the enterprise that are directly traceable to the Zachman Framework primitives, thereby ensuring that the architecture models all elements that are necessary to completely describe the enterprise.
