A framework of requirements tracing using UML

Requirements tracing supports software development work by tracing the changes made to the models. There are two functions in requirements tracing: change tracking and influence analysis. Change tracking is the function of searching the models and model elements in the production sequence. Furthermore, one correction of an element in a model often leads to new corrections to other elements. Influence analysis is the function of finding those elements that need to be additionally corrected. The requirements tracing models are drawn with UML diagrams. UML (Unified Modeling Language) is an industrial-standard visual modeling language established by the OMG (Object Management Group)
