Usability testing


Usability testing is a technique used to evaluate a product by testing it with representative users. In the test, these users will try to complete typical tasks while observers watch, listen and takes notes.

Your goal is to identify any usability problems, collect quantitative data  on participants' performance (e.g., time on task, error rates), and determine participant's satisfaction with the product.

Usability testing is a technique for ensuring that the intended users of a system can carry out the intended tasks efficiently, effectively and satisfactorily.

Usability testing it is carried out pre-release so that any significant issues identified can be addressed. Usability testing can be carried out at various stages of the design process. In the early stages, however, techniques such as walkthroughs are
often more appropriate. Usability testing is not a substitute for a human-centred design process.

A usability testing session should be attended by:
•  A representative user
• A test host.

It is highly recommended to also have in attendance as observers:
•  At least 1 developer.
•  At least 1 business representative.
Observers should ideally be in a separate observation room.
