REQUIREMENTS ENGINEERING TECHNOLOGY

EFFECTIVE USE OF CURRENT FUNCTIONAL AND PROCESS ORIENTED REQUIREMENTS ANALYSIS TECHNIQUES IS DIFFICULT BECAUSE OF THEIR STATIC NATURE AND COMPLEX NOTATIONS. THESE METHODOLOGIES HAVE MOLDED REQUIREMENTS INTO A FUNCTIONAL FRAMEWORK WITH A SYSTEM BEING DESCRIBED IN TERMS OF WHAT IT DOES, NOT WHAT IT IS. OBJECT ORIENTED REQUIREMENTS ANALYSIS, AN EXPRESSIVE AND EASILY ADAPTABLE REQUIREMENTS ANALYSIS METHODOLOGY, MODELS THE PROBLEM DOMAIN(S) IN TERMS OF OBJECTS, ATTRIBUTES, SERVICES, AND RELATIONSHIPS. THIS METHODOLOGY IS DESIRABLE BECAUSE IT ORGANIZES SYSTEMS IN TERMS OF COMPONENTS AND NOT FUNCTIONALITY; HAS STRONG ABSTRACTION AND ENCAPSULATION; AND PROVIDE SIMPLE NOTATIONS AND GRAPHICAL MEANS BY WHICH TO EXPRESS THE REQUIREMENTS TO THE VARIOUS PEOPLE INVOLVED IN THE SYSTEM LIFE CYCLE.
