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.

Abstract
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.File | Dimensione | Formato | |
