... there are no simple 'right' answers for most web design questions (at least not for the important ones). What works is good, integrated design that fills a need--carefully thought out, well executed, and tested.

Faro, Alberto and Giordano, Daniela (1997): Towards a Situated Action Calculus for Modelling Interactions. In: Thimbleby, Harold, O'Conaill, Brid and Thomas, Peter J. (eds.) Proceedings of the Twelfth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers XII August, 1997, Bristol, England, UK. pp. 101-116.

Formal modelling of situated actions and context is a worthwhile endeavor if it provides a framework for verifying requirements correctness and generates principles for building interfaces for fluid interactions. The paper argues that action sequences, rather than states, are a suitable representation for this problem, and proposes a situated action calculus based on a new material implication relation among contexts. The situated action calculus extends in two respects a story-telling theory for embedding the user requirements in meaningful contexts. First, it provides a formalism and a set of operators that allow the designer to verify that stories told by different actors generate a safe and live representation; and second, it allows partitioning such representation in a succession of scenes which can be aggregated to define for each actor an interface that unfolds with the task and the context.

Faro, Alberto and Giordano, Daniela (1997): From Documenting Design to Design By Documenting. In: ACM 15th International Conference on Systems Documentation 1997. pp. 45-54.

User-centered approach to Information Systems (IS) design requires documenting user interfaces in conjunction with the other design documents. The lack of this documentation increases the cost of the user-centered specifications when producing a new version of the user requirements or passing from a system to an analogous one, although in principle it is possible to take advantage from former experience. To facilitate both versioning and reuse of the IS specifications, the paper presents a new organization of the design documentation based on a story-telling theory (STT) previously proposed by the authors. STT-based specifications consist of a set of use stories, each constituted by a sequence of episodes. Within this framework, the paper proposes to structure the IS design documentation as a set of use episodes, each referred to a multimedia document, called scene, illustrating how the episode is enacted by its main character in collaboration with other actors of the story. Scenes are traced to system interface and structure, thus enabling the designer to see how episodes influence the implementation. Moreover, linking the scenes of a project to the analogous ones of former projects results in a collaboratively built design memory appropriate for a reasonable documentation of the design process that facilitates versioning and reuse.
