Linking UAF and SysML Models: Achieving Alignment between Enterprise and System Architectures

Abstract

The Unified Architecture Framework (UAF) is designed to facilitate the modeling of a system (at a high level) along with the driving enterprise objectives and strategies, operational activities and mission threads, capability objectives and roadmaps, and a variety of other considerations that apply to the system under development. However, when the system (or a collection of systems) is modeled using UAFML, there is a challenge in linking the UAF model to the corresponding system models created using SysML to ensure proper alignment is established and maintained between the Enterprise and System levels. This paper examines four alternative ways of achieving this alignment and discusses the benefits and drawbacks of each approach.
