A means of establishing traceability based on a UML model in business application development

This paper describes an easy means of setting traceability in business application artifacts. The traceability is established for completeness verification and impact analysis. There are thousands of functions and screens in real business applications. It is difficult to establish suitable links from these many elements. In addition, there is a constraint that the workload of setting traceability links should be small. This paper proposes a two-step approach to establish traceability in artifacts. In the first step, the software model defines traceability. In the second step, a developer him/herself sets up traceability links during the design phase. The purpose of the first step is to restrict of the set of linkable elements, while the purpose of the second step is to establish links according to the developer´s intentions. We also devise the second step in two points. The first point is to make a developer set up links while he/she is working on the design. The second point is appropriate categorization to reduce the number of candidate links. We also propose a support tool for setting up links. The approach and tool decrease the developer´s workload. This paper provides details and evaluation on this model-based approach and tool.
