Data.gov – Usability Case Study
We all know listening to your customers is important. Not just reading their comments, but talking to them, actually getting in a room with them, and having them test your product. But if basing a whole-scale redesign around one series of user conversations makes you nervous – it should.
That’s because sometimes when we listen, we only see a bit of the bigger picture. It’s only when we get customer feedback, tweak the design, and THEN ask customers a second time that we really validate what customers want. Retesting is called iteration and it’s very powerful.
Data.gov is a very large site run by GSA with a mandate to make government data more transparent, open and customer-focused. They took this seriously and conducted numerous user tests, focus groups and interviews. User testing occurred at four distinct stages:
- before re-design,
- after the first redesign,
- after a second redesign, and
- before launch.
At every stage of their development, they took the new design and opened it up for feedback. They took this feedback, tweaked, and asked again. And again. Over time, as you can see in this usability case study, the design got stronger and stronger.
Data.gov Version #1: May 2013
The initial design, above, is a fairly straightforward informational website. To move it to the next level, they used a combination of face-to-face usability testing and remote tests.
“Over the previous year, some people had complained about Data.gov being hard to use, and so I asked them to be testers. Most of them accepted,” said Jeanne Holm, open data evangelist for Data.gov.
“We listened to users, and they wanted a more dynamic, up-to-date design and stronger search,” she said. So the team tried to make the site more responsive and engaging, and “we gave it a Tumblr-like feel,” Holm said.
The site they created was a page with lots of elements that seemed bloggy and more “social.” The site was made fully functional at a public URL (Next.Data.gov) so that people could watch the design happen and give feedback over time.
Data.gov Version #2: July 2013
There was only one problem.
“There was too much social and not enough structure and context,” Holm said. “There was a cascade of items–some were important, like the release of a new data set, and some were just tweets. Some were White House blogs and some were a comment on a blog.”
Without a structure – without compartments that house the data and give it context – people didn’t know where to go.
“On Tumblr, you tumble for 10 minutes,” Holm said. “You look through what’s there, see what’s of interest, but like on Google+ you’ve already self-filtered content by selecting who to follow. But on a site like Data.gov, you don’t want to look for 10 minutes, you want to find information or data immediately. It’s a completely different audience experience.”
Through a second round of usability testing, the Data.gov team found that people ignored the “floating content” at the bottom. Instead they navigated through the links on the left-hand side – education, energy, etc. These links were originally under the “Community” tab in the first version.
The prominent search feature on top wasn’t enough – customers wanted the ability to both search AND navigate to their information.
So they retooled again.
Version #3: January 2014
Now, they made the communities front and center and called them “topics.” The icons draw people’s attention to them as the sole graphics on the page. It gives equal time to both the search-based navigation on top, Google-style, and then the icons below.
“People wanted to go to communities in first, second, and third iteration of testing,” Holm said. In their journey, “We went from one extreme to the other, and then found a place in between.”
User feedback has been very positive and there are more ways for citizens to contribute to, interact with, and comment on content on the site. But, the team continues to collect and act on feedback that they collect through numerous channels on traditional and social media and at events, and post and respond to them publicly on Data.gov’s Github page. That turns data collection into a two-way conversation.
Said Holm about the entire journey: “Usability tests used to be something we did every year, and now we do them every day. We have these conversations every day.”
