Non-functional attributes

There are 9 key non-functional attributes that should be considered for any Digital Service.  Each organisation’s requirements will be different, and suppliers should work with consumers to decide what is needed. 

1. Performance - speed of processing transactions
2. Security - security levels for protection of data (see Cyber, information governance and data security guidance)
3. Access - permissions, who has access to which service and functionality, and how they access it (see user accessibility and authentication guidance)
4. Backup and recovery - protection against data loss
5. Archiving and retention - duration, methods and eventual deletion
6. Robustness - reliability, data integrity and user error
7. Availability - timeframe for availability of functionality
8. Usability - ease of learning and ease of use
9. Capacity - volumes of data, transactions and users (see network sizing and capacity guidance)
