CDC test of social media: Complexity makes usable design a challenge

Check out the concise summary of "social media usability testing" conducted by the CDC. Covering MySpace, blogs, widgets, e-Cards, and podcasts, the study points to the unsurprising conclusion that complex products - such as widgets - must meet a higher standard of usability and credible user experience.

I'll bracket that statement with two statistics from the study. First the e-Cards: "100% participants worry about viruses/spam." Which, of course, influences the decision to open the e-Card. This is what our Usable Times 5 methodology would describe as a Permission issue - as in, "I did not give you permission to send viruses or spam to my computer." Of course the Web site does not explicitly say it will send viruses or spam. But it doesn't reassure users that they won't have to worry about them, either.

Second, the widget, which only 45% if respondents were able to share and download, caused users to "struggle." Again, a reduction in usage, for different reasons. The loss here is in the development time for that widget, which is then under-utilized due to poor task sequence design. The presentation of user interactivity required for interaction with the widget is not straightforward enough for this user base. Interactivity is another Usable Times 5 factor.

The usability test report also discusses problems with adjacency of controls (instructions for use of podcasts too far from the action button, counter-intuitive "save this file" labeling). This is a common problem easily revealed in usability testing, and solved in user interface design.

The best news: "Visitors who use our new media products are more satisfied
with their visit to CDC’s Web site." That encourages all of us to continue the development of the many diverse expressions that currently fall under the rubric of social media. But these findings also point out the significant gap between the products we create and the user's ability to understand them without us there to explain them.

The need for information design on all digital products remains unmet.

The study, created by Sarah Greer, Catherine Jamal, Mike Peltz
and Cari Wolfson of the CDC's Division of eHealth Marketing, gets kudos for its frank look at CDC's current usage of media tools. No surprise to find FDA's Sanjay Koyani thanked at the end - he was among the first to create Web user experience standards in 2003 with the Research-Based Web Design and Usability Guidelines.
