Strategic Information Planning: Framework for Designing and Developing SystemArchitectures

摘要

Strategic information systems planning is a disciplined, systematic approach todetermining the most effective and efficient means of satisfying organizational information needs. It is a top-down, structured approach which, to be successful, must employ technical and managerial processes in a systems engineering context. Under this approach, the characteristics of the system's hardware, software, facilities, data, and personnel are identified and defined through detailed design and analysis to achieve the most cost-effective system for satisfying the organization's needs. The process must consider system life cycle management and the organization's policy and budget as important integral factors, and include all organizational participants (e.g., managers, users, maintainers, operators, and designers) throughout the process. It is an iterative process in that changes identified during the process must be evaluated to determine their effect on completed analyses. Strategic information systems planning is not a one-time event-it should be revisited periodically to ensure a system's continued viability in meeting information needs and achieving long-term missions.
