A visual software requirements definition method
Akira Ohnishi A · 2002
The author proposes a visual software requirements definition method including the description of a visual software requirements specification (SRS) with a visual requirements language and executing the SRS. The method proposed provides a describer for defining both the shape and semantics of icons to specify the requirements as he imagines them. The method also provides for describing icons' movements as a scenario description. This scenario enables an execution of the SRS with animation. The describer can confirm his requirements by checking the animation. A visual requirements language named VRDL and tools are illustrated with examples. The visual requirements specification method proposed contributes to improve the understandability of an SRS and the easiness to write the SRS. The method also improves the correctness of the SRS.>
