A 'Systems of Systems' Perspective of the Year 2000 Problem

摘要

A "System of Systems" perspective of the Year 2000 (Y2K) problem is crucial for any organization that owns or operates computer-based ssytems that interface with other systems, especially large multi-computer ssytem programs. This paper focuses on the requirements, multiple systems and interfaces, functional analysis, threads, testing, and multi-organizational Y2K coordination issues inherent in all large Y2K certification programs. In addition, the positive long-term benefits of reengineering and documenting the program's functionality, physical architecture and products are also discussed. Special emphasis is placed on the importance of "System Threads", key to capturing the essence of very complex system interface issues and the prioritization of resource allocations and organizational activities.
