Patent ID: 8893075

Claim:
A method of providing screen use diagram-based representation, comprising: obtaining one or more instances of actors, one or more instances of screens, and one or more instances of use cases representing a system; representing each of said one or more instances of actors, said one or more instances of screens, and said one or more instances of use cases in a screen-use diagram; creating one or more associations between said one or more instances of actors and screens in the screen-use diagram; and creating one or more associations between said one or more instances of screens and use cases in the screen-use diagram, wherein the screen-use diagram is further capable of presenting one or more prospective items, said one or more prospective items representing placeholders for specification of one or more of actors, screens or use cases not yet created, wherein the one or more instances of actors, the one or more instances of screens, and the one or more instances of uses cases have respective computer-implemented data representations that exist independently of the screen-use diagram, wherein the respective computer-implemented data representations that exist independently of the screen-use diagram continue to exist even if the screen-use diagram representing said one or more instances of actors, said one or more instances of screens, and said one or more instances of use cases is deleted, wherein said one or more associations between said one or more instances of screens and use cases in the screen-use diagram are specified in the screen-use diagram independently of said respective computer-implemented data representations.
