To implement a web site which users find effective, efficient and satisfying requires a user centred design process. This document describes a process which integrates existing empirical evidence and guidelines for web site design into a user-centred process which is consistent with ISO 13407 . Due to limitations of space, the reader is referred to the references for more details of the individual design guidelines. It is essential first to define the business objectives and usability goals , and to specify the intended contexts of use . These should drive an iterative process of design and evaluation, starting with partial mock-ups and moving to functional prototypes.
Continued usability requires subsequent management and maintenance.
These could include disseminating information, advertising services, selling products, positioning in the market or demonstrating competency. Identify responsibilities for achieving quality and usability objectives, and estimate the resources and budget for these activities. Even if there is no definitive answer to these questions, it is important to obtain agreement on the assumptions which are made. Define key scenarios of use Describe specific examples of how and why people will access the site , and what they want to achieve. These will help prioritise design, and should be the focus for evaluation.
