And an application that worked reliably gained a reputation as being more stable, and therefore more desirable. But today, neither features nor reliability provides the most useful measure of a successful application or web site. There have been so many features packed into today's software and web sites that most people only ever use a small percentage of them. Colorful graphics, animations, and banners have been employed to attract and engage people, especially to web sites. Today, what makes a web site or application successful is the user experience .
People expect to find what they're looking for.
They want to accomplish their tasks with a minimum of effort. They want to enjoy the experience. And if they do, they'll want to come back. Think about some of the negative experiences you've had with applications and on the web. Chances are they were the result of a poor user interface.
