  abstract = {Cost estimation of changes to software systems is often inaccurate
	and implementation of changes is time consuming, cost intensive,
	and error prone. One reason for these problems is that relationships
	between documentation entities (e.g., between different requirements)
	are not documented at all or only incompletely. In this paper, we
	describe a constructive approach to support later changes to software
	systems. Our approach consists of a traceability technique and a
	supporting tool environment. The tracing approach describes which
	traces should be established in which way. The proposed tool environment
	supports the application of the guidelines in a concrete development
	context. The tool environment integrates two existing tools: a requirements
	management tool (i.e., RequisitePro) and a CASE tool (i.e., Rhapsody).
	Our approach allows traces to be established, analyzed, and maintained
	effectively and efficiently.},
