A practical application of object-oriented enterprise modeling

Abstract

As the Air Force and Navy look forward to replacing outdated resources, it became apparent that a better understanding of and an accurate analytic model for, the existing process of training pilots and navigators was essential. Object oriented analysis (OOA) was selected to make use of the perceived advantages it offers such as data modeling, encapsulation of objects and their behavior, the potential for reuse, and its ability to scale-up to huge systems. The goal of the analysis was to create a set of OOA models that describes: (1) the implementation of the current (physical) enterprise; (2) the essential (logical) enterprise requirements of a combined Air Force and Navy integrated training management system; and (3) the essential (logical) enterprise requirements of an enhanced combined Air Force and Navy integrated training management system. The enterprise models will be used as a springboard for the development of requirement specifications for a training integration management system (TMS). TMS will be an automated system that manages all undergraduate flying/aviation training. It will support the Ground Based Training System. We present the steps taken in the analysis and modeling process for the creation of these enterprise models including: (1) object-oriented methodology, CASE tool and database selection; (2) user-driven paradigm mix and migration, (3) data collection process; (4) classification and development of class/object views: 5) development of information (functional) flow views; (6) development of dynamic (time dependent views; (7) user validation of current enterprise views; (8) future system enhancements and improvements; and (9) lessons learned.
