If only one out of 1000 users encounters a problem with a website, then it’s a minor problem. If that sentence bothered you, it should. It could be that that single problem resulted in one visitor’s financial information inadvertently being posted to the website for the world to see. Or it could be a slight
Traveling is hard. Traveling with children is especially hard. A number of things can go wrong, making the trip difficult or even nonexistent.

A lot happens when you observe a user during a usability test. There’s the interface, the utterances, the body language and the metrics.

It’s good to think positively, but sometimes, negative thinking can solve problems more effectively. There’s no shortage of problems on websites and software. Many of them are interaction problems. Users can’t login Visitors can’t find the products in the navigation Customers are calling support Sales are low Conversion rate are down Fixing Symptoms not Problems

A focus on finding and fixing problems by testing early and often with small-samples generates major insights. More recently Steve Krug has taken this informal approach to the masses by encouraging website owners
Just how common are usability problems in websites and software? Surprisingly there is very little out there on the frequency of usability problems.

Does this man need back surgery? Does this woman have breast cancer? Does this website have usability problems?
