Positive user experience as formula for success
Therefore the software-development process must definitely be flexible and economical; a needs analysis is vital. Nowadays a successful user interface is not a “nice to have” but a “got to have”, if a product is to be successful. Factors such as the interface and interaction design play a major role in this.
For good usability the user requires specific technical and aesthetic characteristics, good performance, and an intuitive interface which can be operated with just a few clicks (click-through rate).
Thus the aim is to attain positive user experience – no matter whether it is an application, a website, an app, or individual software.
