Ilities

Within systems engineering, -ilities are Aspect (computer science) 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.

The -ilities often include:

accessibility,

accountability,

accuracy,

adaptability,

administrability,

affordability,

agility,

availability,

composability,

configurability,

customizability,

degradability,

demonstrability,

Dependability,

deployability,

distributability,

durability,

evolvability,

extensibility,

fault tolerance,

flexibility,

footprint,

Interoperability,

maintainability,

manageability,

mobility,

nomadicity,

openness,

performance,

portability,

predictability,

preliability,

reliability,

responsiveness,

Reusability,

safety,

scalability,

seamlessness,

Information security,

serviceability (a.k.a. supportability),

simplicity,

stability,

survivability,

tailorability,

testability,

timeliness,

trust,

understandability,

Usability

Many of the -ilities can be applied to data quality.
