With the winter season fast approaching, Iteris is excited to announce that a fully redesigned and upgraded version of Iteris’ Maintenance Decision Support System (MDSS) mobile app will be available on October 1.
To ensure the redesigned app meets the needs of both state departments of transportation and municipalities, Iteris conducted several usability studies with a wide range of maintenance personnel. This helped us better understand how real users interact with the application with a view to using that information to improve the user experience (UX) in the upgraded app as much as possible.
Making use of usability studies
As part of these usability studies, participants were asked to accomplish several typical tasks, but were not given any assistance on how to complete them. This restriction ensures that the test environment was as close to an “at-home” scenario as possible.
“We monitored how users interacted with the application and measured both their success rate and the time it took to complete each task,” says Yusuke Imamura, senior UI/UX designer at Iteris. “In addition, a remote application was used to record the participant's screen movements, facial expressions, verbal comments, stress levels and other relevant information.”
“While it is important to run usability studies with multiple people, hundreds of people are not needed,” according to Yusuke. “Since five participants will discover about 85% of usability issues, participant pools can be kept small so additional usability studies can be run with fresh participants after application tweaks from the initial study are made.”
Letting the data decide
Data obtained from these usability studies then informs the adjustments needed to be made to the application before final deployment.
Adjustments are based upon participant feedback and can range from:
- simple bug fixes, to
- new color schemes, to
- a complete redesign of certain sections of the app.
As a result of our extensive usability testing, the new, fully redesigned and updated MDSS mobile app offers users a seamless, intuitive UX with a clean, modern interface. But don’t take our word for it, download the upgrade on October 1 and let us know for yourself.
