This paper presents an architecture modeling approach for service-oriented architectures such as the Net-Centric Enterprise Services NCES. The approach is driven by operational mission threads. It uses Unified Modeling Language and the Department of Defense Architecture Framework to capture, analyze, and present the architecture products. Steps in this approach include 1. Formulating activity models for a mission thread. 2. Mapping the activities to NCES and existing systems. 3. Developing logical deployment architecture with NCES included. 4. Developing logical data models. 5. Constructing executable architecture models. This architecture development approach has been applied to NCES mission threads, which cover a wide range of activities in the Warfighting, Intelligence, and Business domains. It provides a direct trace from NCES capabilities to operational requirements and shows how NCES will support various communities of interest. We illustrate the approach using mission threads that are closely related to Command and Control. Examples include Time-Sensitive Targeting, Joint Close Air Support, and Global Strike.
