Usability & Usability Testing

Articles and Resources for Usability and Usability Testing.

Efficacy of Usability

Usability is a general term that encompasses everything having to do with "ease of use." That is, how easily people can use any product's controls or displays such as a: tool, computer display, automobile, aircraft, etc. Usability also refers to the study of methods, measurement, and principles of a product's efficiency, elegance, and usefulness. In the computer industry, usability often refers to the ease of use in terms of the human-computer interaction. The clarity, intuitiveness, seamlessness, and elegance of an application or website interface design.

The idea behind usability is to design products with the user in mind. Putting the user first in the design process results in greater efficiency, learning time, and satisfaction. This process is often referred to as an optimized "user experience."

To achieve an optimized user experience requires a systematic approach to usability in the design process. This is accomplished through expert empirical usability testing where naïve users can be observed to determine what works and what does not work. Changing the design parameters to accommodate the results of usability testing permits an optimized user interface design.

The goal of optimized usability is to make a product easy to understand, easy to use, and easy to learn. The outcome of good usability is a greater likelihood of user acceptance. User acceptance is often the difference between a product's success or failure in the marketplace. Users can often reject a well engineered product with great functionality if they are unable to understand, learn, and easily use that product.
