Why to test?

2013

“If you want a great site, you’ve got to test. After you’ve worked on a site for even a few weeks, you can’t see it freshly anymore. You know too much. The only way to find out if it really works is to test it.”

– Steve Krug, Don’t Make Me Think

Why to test?

• Find out usability problems

• Why products, services and websites fail

• Understand how users think

• Risk reduction

• No surprises

Does not help to answer

• Do people like it

• Will people buy it

• How people will use it mostly

• What kind of people will use it

• What solution is better A or B
