To receive all the full articles and support ByteByteGo, consider subscribing: Non-functional requirements (NFRs) are as critical as functional requirements because they define a system's qualities and operational parameters. Functional requirements specify what a software product should do (for example, “users must be able to log in”). However, non-functional requirements define how well it must accomplish these tasks under real-world conditions (for example, “the login process should respond within two seconds under peak load” or “all user credentials must be encrypted and stored securely”). Together, functional and non-functional requirements create a foundation for building great software systems. In Part 1 of this topic, we also looked at trade-offs in non-functional requirements and the architectural impact of these requirements. Some key learning points from Part 1 were as follows:
In this article (Part 2), we’ll go further and look at some of the most important NFRs that should be considered while building systems.
Key NFRs to ConsiderSome key non-functional requirements that should be considered while designing an application are as follows: Response Time/Latency... Continue reading this post for free in the Substack app
