Abstract:
A requirement acquiring system comprising:means for inputting a requirement by using a requirement input device, said requirement input device including:means for arranging components of a development subject on a screen of a computer terminal;means for specifying, for each of the arranged components, a component name, a data item name, and a procedure name to be held by said component;means for displaying, for each procedure of the component, a list of procedures held by a component as a menu, selecting from said menu a procedure call sequence between components containing said procedure or a procedure call sequence within the component, repeating said displaying operation and said selecting operation, and thereby specifying a procedure call sequence held by the component, said procedure call sequence being an order of calling procedures held by components;means for generating component data, procedure call sequence data and scenario data, said component data having a record of said specified component name, data item name and procedure name, said procedure call sequence data having a record of said procedure call sequence, said scenario data holding names and peculiar numbers for said component data and said procedure call sequence data;said means for specifying a procedure call sequence held by the component comprising means for responding to a certain component name and a certain procedure name included in first scenario data of a certain requirement having identical names with a component name and a procedure name included in second scenario data, and means for specifying identity of the component and the procedure of the second scenario data with the component and the procedure of the first scenario data;means for generating identification data in each scenario data on the basis of a scenario peculiar number of each of said scenario data specified in identity;means for separately defining, for each requirement, procedures to be called subsequently to said procedures specified in identity and generating separate scenario data;means for generating whole identification data from said generated identification data of the scenario data;means for generating relation data among whole visualized requirements as scenario relation data from identification data of a group of requirements generated by said repetition; andmeans for displaying figures representing all of the requirements, and for displaying connection lines between relating requirements, on the basis of the relation data of the scenario, and thereby displaying relation data of the whole scenario.
