Usability testing

Goal

To determine whether the end-users can easily understand and operate the artefact.

What

A non-functional testing method to measure how easily end–users can use the artefact, in terms of efficiency, effectiveness and satisfaction.

Where

This can be done in a labatory setting controlled by the evaluater. This also can be done in practice. The more practical the better the actual real life input  but also more risk for noise in the evaluation. 

Who

users, evaluator

How

Describe the users age, gender, their experience, if they have seen this solution or a similar solution. Usability studies could be recorded with video and audio, this could also take away the ‘natural’ behavior.

2. Setting up environment for the study.
3. Creating or using a validated questionnaire (Examples are: SUS questionnaire  technology acceptance models or specific questionnaires created within the context of your problem.)
4. Executing usability study
