Note
We based this repository on an article we wrote on Medium titled Understanding Software “-ilities”: Key Attributes of Quality Software.
In software engineering, "-ilities" refer to a wide range of attributes that determine the quality, performance, and maintainability of software systems.
These are sometimes called architecture characteristics or "ilities" due to the common suffix many of the words share.
Primarily considered non-functional requirements, these attributes are critical for evaluating and ensuring that software meets user requirements and operates efficiently in various environments.
Below is a comprehensive list of 100 "-ilities" that I've gathered from around the web and my own work over the years. This is not an exhaustive list, but it covers many of the key attributes that determine the quality and performance of software systems. I'm sure you can think of more to add to this list, as there is no official or universally accepted list of software "-ilities."
Once you see the list of "-ilities", you will not be able to unsee it. You'll notice them everywhere in every discussion you have around software and systems, so it's time to formally meet them!
The Big List of Software "-ilities" is maintained in the -ilities.md file located in the root of this repository.
ex.
- Scalability
- Reliability
- Maintainability
- Usability
- Availability
Note
Over time, we will add descriptions and the importance of each -ility. For now, consult our Medium article here.
