System Fundamentals^[1]

In software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use ^[2].

Any discussion of usability must include the idea of ergonomics and accessibility.

Do I understand this?[edit]

You should be able to close your eyes and recite from memory this idea of usable and usability. However, I hope you take a moment to think more deeply about this idea. From this article, we learn usability might be decomposed into:

"The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use"^[3]

This definition can be expanded, and made more comprehensive, by including five characteristics which must be met for the users of a product:

Effective
Efficient
Engaging
Error Tolerant
Easy to Learn

Standards[edit]

Define the term usability.
