+Following the [ISO-25010](https://iso25000.com/index.php/en/iso-25000-standards/iso-25010) standard, we define the following quality requirements for our system:
+
+## Performance Efficiency
+
+* Time behavior: When a submitter uploads a sequence, then the sequence should be available for querying within 10 minutes.
+* Time behavior: When a user queries a sequence, then the query should return within 1 second.
+
+## Interaction Capability
+
+* Operability: A maintainer should be able to set up a new Loculus instance from reading the documentation.
+
+## Security
+
+* Confidentiality: Only submitters belonging to the respective group should be able to make changes on sequence data.
