Making Use: Scenario-Based Design of Human-Computer Interactions >>>> http://newbook.space/?book=0262513889 Difficult to learn and awkward to use, today's information systems oftenchange our activities in ways that we do not need or want. The problem lies in thesoftware development process. In this book John Carroll shows how a pervasive butunderused element of design practice, the scenario, can transform informationsystems design.Traditional textbook approaches manage the complexity of the designprocess via abstraction, treating design problems as if they were composites ofpuzzles. Scenario-based design uses concretization. A scenario is a concrete storyabout use. For example: A person turned on a computer the screen displayed abutton labeled Start the person used the mouse to select the button. Scenarios area vocabulary for coordinating the central tasks of system development--understandingpeople's needs, envisioning new activities and technologies, designing effectivesystems and software, and drawing general lessons from systems as they are developedand used. Instead of designing software by listing requirements, functions, and codemodules, the designer focuses first on the activities that need to be supported andthen allows descriptions of those activities to drive everything else.In addition toa comprehensive discussion of the principles of scenario-based design, the bookincludes in-depth examples of its application. >>>> http://newbook.space/?book=0262513889
