Software Usability

A measure of how well the system interacts with end-users. Typical definitions refer to SoftwareUsability as a composition of several factors, such as:

• Learnability
• Efficiency/Throughput
• User Appeal / Subjective Satisfaction
• Memorability(note this can differ from learnability - e.g. it's hard to learn to ride a bike, but easy to remember how to do it)
• Usefulness.

The discipline concerned with studying and improving usability is HumanComputerInteraction.

Software which is usable is OnMySide, and doesn't get InMyWay.
