I am such a big fan of usability, my tie-break question when I am working on digital projects is always “what does the user think?”. I am also a big fan of usability testing, although watching it can be painful. I know I’m not the only digital expert to have been shouting at the person taking the test in another room “click on it”.
Put simply usability makes things better. When your site is usable time to learn how to use it decreases, people can recover from an error faster, the logic of the information and use is apparent. In short, from the user perspective the technology fades into the background
Usability also matters in real life.
In the Amsterdam metro the carriage doors include lights with the colour coding – white showing which door will open turning green to show it’s safe to go through the door, and then red to show it’s not. There are also announcements telling you which side of the carriage will open. These steps were taken to improve the usability of the metro network for people with vision impairment or poor hearing, but they work for the rest of us too.
Usability thinking also extends to how information is organised. I find Dutch train timetables easier to read than the Belgian counterparts. The Dutch include a schematic above the timetable to tell you which stations you can reach using the timetable below it, it’s a form of structured navigation. The Belgian timetables are organised by time only – it’s an endless scroll.
Bad design is not just time consuming, it increases the risk of error.
In January the citizens of Hawaii heard or received an alert stating:
BALLISTIC MISSILE THREAT INBOUND TO HAWAII. SEEK IMMEDIATE SHELTER. THIS IS NOT A DRILL.
It turned out to be a false alarm. There were a number of contributing errors and when you see the menu used to select the drill you can see how easy it was to confuse the options.
If you’re designing anything, use experts, it really makes a difference. If you’re creating content for online there are some simple rules to follow.
And if you get some entertainment value out of seeing other people’s UX mistakes, I recommend the Bad bad UX instagram account.
