A traceability link model for the unified process

Traceability links are widely accepted as efficient means to support an evolutionary software development. However, their usage in analysis and design is effort consuming and error prone due to lacking or missing methods and tools for their creation, update and verification. In this paper we analyse and classify Unified Process artefacts to establish a traceability link model for this process. This model defines all required links between the artefacts. Furthermore, it provides a basis for the (semi)-automatic establishment and the verification of links in Unified Process development projects. We also define a first set of rules as step towards an efficient management of the links. In the ongoing project the rule set is extended to establish a whole framework of methods and rules.
