Requirements definition and management (RDM) tools streamline development teams’ analysis of requirements, capture requirements in a database-based tool to enable collaborative review for accuracy and completeness, ease use-case and/or test-case creation, provide traceability, and facilitate documentation and versioning/change control. Increasingly, RDM tools support business analysts with graphical tools for process workflow definition, application simulation and prototyping, and other visual, collaborative tools. The database approach uses special-purpose repositories that are part of the requirements management solution or ship with a general-purpose commercial database integrated with the tool.
