A method for bi-directional synchronization of tracing relationships between a requirements repository and textual requirements documents, including: in a first operating mode: gathering trace information from a requirements repository; and formatting the trace information and inserting the trace information as text in textual requirements documents; and in a second operating mode: modifying the trace information in the textual requirements documents; and updating the requirements repository to match the modifications that were made in the textual requirements documents.

Method and system for bi-directionally synchronizing tracing relationships between a requirements repository and textual requirements documents

A method for modeling requirements of a product includes defining an abstract use case for each feature of said product, hierarchically decomposing each abstract use case until concrete use cases are specified for each feature, depicting every actor who would use the product as communicating with a concrete use case through a boundary, and programmatically extracting requirements from the use case diagram. Programmatically extracting requirements further includes converting use case diagrams into directed acyclic graphs, where each use case corresponds to a node of a graph and each relationship between a pair of use cases is represented by a directed edge between the corresponding pair of nodes in the graph where a directed edge points from a parent node to a child node, converting the directed acyclic graph into a tree, and searching the tree to extract the requirements.
