One of the virtues of the Web is its ability to facilitate customization. Web technology allows organizations to move beyond one-size-fits-all interfaces and products, allowing users to define and design their own experiences. Custom homepages and Web based design-it-yourself processes are numerous and users appreciate the concept of customized experiences. This report from the Nielsen Norman Group addresses:
Usability of Interface Customization Web sites (custom homepages)
Usability of Product Customization Web sites (custom stationery)
Guidelines for improved customization task success and user satisfaction
The report does not cover personalization, where a software system tries to predict individual users’ needs automatically. It is solely about designs where users themselves employ features to manually customize or configure the UI or a product.
