Which of the following statements clearly defines the system context?

The selected statement accurately captures the essence of a system context. The system context provides a comprehensive view that encompasses all elements surrounding the system, including stakeholders, interactions, and external factors that influence its functionality and requirements. By including "all aspects that are not relevant to the planned system," it emphasizes the importance of defining boundaries, understanding interactions with external environments, and recognizing influences that inform the system's design and functionality.

This holistic approach is crucial for stakeholders to comprehend how various elements and interactions will shape the system, helping to identify requirements and constraints effectively. It's vital to consider both what is inside the system and what exists outside it, as these external factors can have significant implications for the system's success.

Understanding this definition deepens one's insight into the broader context of system development, facilitating better communication among project members and clearer requirement elicitation from stakeholders.
