The Bull’s-Eye framework and the resulting set of guidelines are a step forward from where we started. The levels of the Bull’s-Eye provide a framework for thinking about how all the types of guidelines work together, from the general principles to the specific components. With this framework we bridged the gap left by other guidelines and standards, as well as designed for a wide range of users and application domains.

The Bull’s-Eye: A Framework for Web Application User Interface Design Guidelines(1) - 22 September 2006

by Betsy Beier and Misha W. Vaughan in Methods

A multi-leveled framework for user interface design guidelines of Web applications is presented. User interface design guidelines tend to provide information that is either too general, so that it is difficult to apply to a specific case, or too specific, so that a wide range of products is not supported. The framework presented is unique in that it provides a bridge between the two extremes. It has been dubbed the ‘Bull’s-Eye’ due to its five layers, represented as concentric circles. The center of the Bull’s-Eye is the Component layer, followed by Page Templates, Page Flows, Interface Models and Patterns, and Overarching Features and Principles. To support this approach,requirements were gathered from user interface designers,product managers, UI developers, and product developers.
Also, usability testing of the guidelines occurred on several levels, from broad guideline tests to more specific product tests. The guidelines and lessons learned are intended to serve as examples for others seeking to design families of Web applications or Web sites.
