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.
