Software development support apparatus, program and method

The invention provides a software development support apparatus, a program and a method thereof. Before design information is published, a consistency state of reference design information referred to by the design information is revealed. By this, it is possible to reduce waste caused by redesign or the like of the design information. Public design information used for designing the design information is stored as reference design information into a developer design information storage part (S5). When a developer requests publication of the design information that has used the reference design information, the design information is stored as public design information into a public design information storage part (S17). When the design information is stored in the public design information storage part, a consistency state between reference design information of design information that uses the design information and the design information is verified (S19), and the verified consistency state is stored in a c
