Within systems engineering, -ilities are aspects or non-functional requirements. They are so-named because most of them end in "-ility."
A subset of them (Reliability, Availability, Serviceability, Usability, and Installability) are together referred to as RASUI.
For databases RASR is an important concept (Reliability, Availability, Scalability, and Recoverability). The "-ilities" often include:
- accessibility
- accountability
- adaptability
- administrability
- affordability
- agility
- availability
- composability
- configurability
- customizability
- degradability
- demonstrability
- dependability
- deployability
- distributability
- durability
- evolvability
- extensibility
- flexibility
- installability
- interoperability
- maintainability
- manageability
- mobility
- nomadicity
- operability
- portability
- predictability
- recoverability
- relevance
- reliability
- repeatability
- reproducibility
- reusability
- scalability
- seamlessness
- serviceability (a.k.a. supportability)
- securability
- simplicity
- stability
- survivability
- tailorability
- testability
- timeliness
- understandability
- usability
- haniability
Many of the "-ilities" can be applied to data quality.
