Assessing the true quality of software requires a deep dive into its fundamental requirements. This tier list ranks key aspects that define excellence, from the crucial **Lastverhalten** (load behavior) that ensures stability under pressure, to the bedrock of **Funktionale Korrektheit** (functional correctness) that guarantees features work as intended. We also evaluate **Performance**, ensuring speed and efficiency, alongside the vital **Security** to protect against threats. Finally, **Testbarkeit** (testability) is considered, acknowledging how easily a system can be verified. Understanding these elements is paramount for building robust and reliable software.
