Usability Evaluation
Remember usability relates to how easy it is for a user to interact with a system or product.
We need to test how a user interacts with a system. This could be an existing system we want to replace or our own design.
We can test this by observing the user use an existing system. Such as navigating a website, using an application, setting up a computer, or playing a video game.
We can use focus groups and surveys to get people to evaluate our designs.
One way to achieve this is to create a wireframe mock up of the user interface and observe how people interact with it.
