Usability Testing
Usability testing is one of the evaluations carried out during the process of developing a new product in order to ensure that the outcome meets the established objectives. It also makes it possible to identify errors in time and implement modifications according to the problems detected.
According to ISO 9241-11, usability is defined as: "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."
Usability testing makes it possible to conduct an in-depth analysis in order to identify contradictions and inconsistencies in product development. These tests can be carried out either by experts or by end users themselves. Through their interaction with the product, participants provide valuable insights into their perceptions and experiences while using it.
It is recommended to conduct more than one usability test in order to collect a greater amount of data for analysis.
In addition, if the issues identified during testing are resolved while the product is still in the prototype stage, it will be easier to implement solutions without incurring the costs associated with modifying the entire production process.
For this reason, usability testing is of great importance and can be extremely useful when properly conducted to collect the most relevant data based on the metrics being used.
