How to conduct a usability test?

Usability testing is checking the usefulness of a design before starting to build it.


Depending on sample size, usability testing takes around 1-3 weeks.

usability  testing is conducted during the design and development phase of a project, after the initial prototypes have been developed. 

Getting Started

Usability testing aka UT is making the actual people try the designs to check if they are able to use it or not. Basically, it’s a process of evaluating how easy it is for users to interact with a product, website, or software application.

UTs are important milestones in the iterative design process.  Design is iterated till UT results show acceptable quality. This method brings in user’s feedback into the product design process and makes the design ‘user centric’ in true sense.
