Tasks set
For the analysis of requirements and within the framework of user experience tests, supplementary online enquiries can be employed in pursuing various problems:
Method
When enquiries are to address visitors who are exploring an offer, participants can be recruited via pop-up windows or links that are permanently installed. While scripts ascertain that only every nth visitor receives an invitation, cookies prevent visitors getting invited repeatedly. Moreover, diverse online panels can be consulted in case the questions also extend to other products by competitors.
The questionnaire can be designed in correspondence with the layout of the web site under discussion.
Sample
In order to obtain reliable results that also consider subgroups, as many respondents as possible ought to be questioned. As a means to measure significant differences between the subgroups each subgroup should consists of about 200 participants.
For a representative sample the enquiry has to stay online at least for a week; this increases the likelihood to reach and include persons who are rarely online.
Timing
If the field phase spans a week, the total duration of the project will be approximately 4 weeks.
