Is it really worth spending half a day fixing these drop-down menus to save a customer a few seconds? For mass-market software, it’s never just one customer: it’s thousands, sometimes millions of customers using the software repeatedly The few seconds of customer time quickly adds up to years A tiny frustration becomes a frequent annoyance Finding an extra half-day to devise a solution is a small problem compared to creating an army of irritated customers go Download from WoweBook.com Take Line 9— but which direction? Download from WoweBook.com Simplicity happens in the user’s head If you overload any machine, it starts to creak and slow down under the stress The same is true for people Give us too many things to remember and we’ll forget, too many tasks to juggle and we’ll drop one, too many decisions to make and we’ll freeze Making software usable means not exceeding your users’ capacity However, users always demand more detailed information, more choices, more stuff—it’s human nature So the tendency is to design usable experiences right up to that maximum—stopping just short of overloading the user Simple experiences don’t that They leave the user with plenty to spare What happens to all that “unused” capacity? A travel firm once asked my company to compare customers’ experiences of researching holidays online and through brochures Watching customers plough through websites, reviewing detailed information and options, we were struck by how tense and irritable they were The brochures were far simpler: some large photos of a resort, a few icons highlighting key features, and a table of prices When they looked through the brochures, customers were relaxed, imagining what the holiday could be like They enjoyed themselves Simple experiences leave users with enough capacity to think about how what they’re doing fits in with their lives A simple camera like The Flip lets users concentrate on capturing the moment, a simple DVD remote control allows users to focus on the movie Don’t try to fill the user’s mind with your design Designing for simplicity leaves your user enough room to fill in details from his or her life and create a richer, more meaningful experience go Download from WoweBook.com Download from WoweBook.com This page intentionally left blank Download from WoweBook.com Photo Credits Part Why are we here?
