According to usability.gov, usability testing refers to “evaluating a product or service by testing it with representative users. Typically, during a test, participants will try to complete typical tasks while observers watch, listen and takes notes. The goal is to identify any usability problems, collect data and determine the participant’s satisfaction with the product.”
Similarly, Wikipedia also states that “in all cases, however, there are certain aspects of user experience that researchers are interested in (measures), and certain procedures and techniques used for collecting the data (methods). There are many measures and some high-level constructs of user experience that can be used as the basis for defining the user experience measures.”
Following on the same line of thoughts, it can be argued that usability measures how effectively users utilise the mobile web platforms to achieve their goals, from start to finish. By properly managing the touchpoints, businesses can reduce the number of expenditures while improving the productivity and maximising profit margins.
As a result, many organisations are starting to adopt usability testing as part of user experience practice – through the implementation of user-centred design (UCD) methodology, allowing designers and developers a freedom to interact with the users directly when building mobile web platforms. This enables developers to make any necessary modifications at an early stage of the product or service prototype whilst developing mobile web platforms
