The entire system-building effort is primarily driven by which factor?

The primary driving factor behind the entire system-building effort is user information requirements. This concept emphasizes that the development of any information system should start with a deep understanding of what users need from that system. By focusing on user requirements, developers can ensure that the system meets the necessary specifications and provides the desired functionalities, ultimately enhancing user satisfaction and productivity.

User information requirements dictate the features, data, and processes necessary for the system to effectively support users in their tasks. These requirements serve as a foundation for design decisions, shaping the system's architecture, interface, and operational capabilities. When users’ needs are prioritized, it leads to a more relevant and effective system that aligns with the organization's goals and improves overall performance.

While factors like organizational change, feasibility studies, and the information value chain are relevant to the system-building process, they all serve to support the primary driver, which is understanding and fulfilling user requirements. Addressing these user needs directly influences how other aspects are handled throughout the system development life cycle. Therefore, a clear focus on user information requirements drives the proper alignment of resources and ultimately contributes to the success of the information system being developed.
