Abstract The purpose of this paper is to demonstrate how an Object Oriented Systems Engineering (OOSE) methodology developed at Lockheed Martin (LM) Management and Data Systems (M&DS) is being applied to the Army Global Command and Control System (GCCS‐A). This system is now migrating from a legacy Army system to a modern integrated Army wide system that supports the Joint GCCS. The focus of this paper is on providing practical examples of how some fundamental issues for using System Engineering methods (previously accomplished with structured analysis and design techniques) in conjunction with software OO methods were resolved using this OOSE methodology. These include: (1) how the system and software requirements specification must be synchronized; (2) capture of requirements and system design information using Object Oriented (OO) techniques and relationships; and (3) using the system objects to better manage the allocation of functionality in the system, maintenance of a legacy system, and ease of system analytical model maintenance during periods of requirements change.
