IA Summit 2016 Main Conference Talk
Topic(s): navigation and usability testing
One of the biggest potential mistakes a manager can make is to over-interpret the results from user research. For example, it is very easy to gain a false sense of confidence when presented positive results from a first click or tree test. In our research we wanted to examine how strong (or weak) the correlation is between early user research results and final live site performance.
In our presentation we will share data from a series of large scale online studies. In each study we looked at how well each method predicted performance in the final live site. The methods/artifacts we have looked into are: tree testing, first click testing (with high and low visual fidelity mockups), and a prototype (with high visual fidelity). This research is critical for any UX researchers or designers whom only rely on early user research methods or need to help their management set realistic expectations.
