“It really just means making sure that something works well: that a person of average ability and experience can use the thing – whether it’s a web site, remote control, or revolving door – for its intended purpose without getting hopelessly frustrated.”

– Steve Krug

“Ford’s quality ratings plunged and a

feature meant to increase loyalty

instead damaged perceptions of the

company.”Nick Bunkley, NYT

Ask Ford.


Do not ask users what they want

"If I had asked people what they wanted, they would have said faster horses."

Henry Ford


Observe them

What users say and what they do are different.

“Provide a simple and convenient payment option”

- PRESTO

“PRESTO – It’s that easy”

“Life is easier with PRESTO”


“Maddening, cumbersome, punitive.”

“I call it ‘PAINSTO’.”

“There are so many terms and conditions on the website. It scares

the crap out of you.”

- CUSTOMERS


“I want convenient, easy and fast fare payment.”


“Uptime of the website meets or exceeds PRESTO standards. Customer convenience features are functional and available.”

Really?


“I am no longer a Presto user.”


You don’t know it’s usable until you test it with users.


Ninja UX: Prototype designs.Test them with users.See where they run into problems.Fix them.


Sweet spot: 5 users


•4-6 tasks

•Create a prototype

•Ask users to “think aloud”

•No coaching!


Bad task:Search for Line 367 - Amount for children born in 1995 or later.

Good task:You are ready to start your tax return. This year, you had your first child. Find information on what deductions you are now entitled to.


“You’re traveling abroad in two weeks and your passport is about to expire. How might you renew it before you go so you don’t need to cancel your vacation?”

“Fill out the Simplified Adult Passport Application Form.”
