In-Depth Information
At this point, you are probably wondering what is meant by usability, and how you
can enhance it. There are many definitions, but essentially, usability is the efficiency
with which a user can perform a required task or business function with a tool.
Efficiency can also spin into multiple examples, but the most common efficiency
metrics are performance, errors, productivity, and user-subjective preferences and
interface characteristics. The chapters in Part VII investigate ways to enhance
usability, mainly from a productivity standpoint. Performance is an important
aspect of usability engineering, but you can read performance-related chapters in
Part VI, “Techniques to Improve Performance.”
A positive user experience is critical to the success of a tool, so it is vital that you
deliver it.
