Which of these is a functional requirement in an IT solution for a racing club?

In the context of an IT solution for a racing club, a functional requirement defines specific behavior or functions that the system must perform to meet the needs of its users. Among the options provided, monitoring race positions is a clear example of a functional requirement. This requirement focuses on the direct functionalities that the IT solution must deliver, such as tracking real-time data about the participants in a race.

Monitoring race positions entails capabilities like live updates, data visualization of the race status, and perhaps reporting functionalities that ensure participants and spectators are informed of current standings. This aligns perfectly with the operational goals of a racing club, where real-time data about races is essential for management, spectators, and participants alike.

While inspecting cars and restricting access may be important for the racing club's overall operations, they are more aligned with procedural or administrative functions rather than direct functionalities of an IT system. Compliance with data protection legislation, while critical for the legality and ethical handling of data, is also more of a regulatory requirement than a functional one. Functional requirements are inherently about how the system behaves, while those other options focus on rules and policies that guide operational practices.
