Abstract
When an IT company introduces a new large scale system, many design documents are created. However, when a specification change of the system happens, the design documents which are related to the specification change can't be extracted efficiently and the engineers can't identify affected range because the extraction of these non-associated documents depends heavily on the experiences of the engineers. Therefore, in order to improve design quality and to introduce the system efficiently, it is of vital importance for the engineers to extract the susceptible affected design documents. In this paper, the method semi-automatically generating metadata to design document and linking design information using the ER diagrams and the CRUD matrixes which are generated in the initial design phase is proposed. Besides, the system of extracting the design documents which are associated to the specification change and specifying impact ranges of the specification changes is developed. In case study, the system is evaluated.
