CONDUCTING A TEST #8

Ethics

It is important to remember that the participants in usability testing are a necessity and that they must be treated with respect. When conducting a usability test the test procedures and conductors must not ask the participant to do anything they do not wish to do or intentionally distress them.

Every member of the test team should understand that users will try to perform as best as they can and may feel pressure to do "well". This is why it is necessary for the test team to make the participant feel as comfortable as possible before, during and after the test. Although the participant has been reassured that the product is being tested and not themselves, they may feel inadequate as they experience difficulties. This may distress some participants and the test team must recognize this and reassure the participant that their performance is not be tested. Additionally, being observed and/or recorded may increase the pressure felt. As an example, the test conductor should not let the user struggle endlessly with a task if it is obvious the user is getting desperate.

Users should also be assured that all information and observations made regarding their performance/participation will remain confidential and that their name will not be used to identify them in any resulting documentation.

Finally, the user should be informed prior to testing that they have the right to withdraw from testing without consequence.

They should then be asked to read and sign an informed consent which summarizes the procedures, purpose of the test, and users' rights. After the test the user should be debriefed and given the opportunity to discuss the test tasks, ask questions, give further comments, and answer any questions the test conductor/team may have.

The user should then be thanked, given their "reward", given a number/name to contact if he/she is interested in test results or to see "improved" product, and dismissed.(Neilsen, 1993 )
