Title:
Managing Usability Requirements in Interactive Systems Development
Abstract: Usability requirements have a crucial impact on
the process of developing interactive systems. Translating usability requirements
into an effective interaction design that supports effective interaction
styles is a considerable challenge to interaction designers. During the development
process, usability specialists need to select proper usability evaluation
techniques in order to ensure that the interactive system under development
meets its usability specifications. To set the usability requirements for
any interactive system, designers need to be able to articulate the attributes
of usability that will make or break the systems. Translating usability attributes
into usability requirements, and managing usability activities is the focus
of this paper: how to identify usability attributes? Why they tend to differ
from one definition to another? Why identifying them is crucial to the success
of the interactive system? Finally, how managing usability requirements can
lead to an effective user-centred development approach?
