I would like to learn about the leading requirements management tools that help organizations capture, analyze, document, and track software or system requirements throughout the development lifecycle. Which platforms—such as IBM DOORS Next, Jama Connect, Siemens Polarion ALM, Azure DevOps, Jira with plugins, Visure Requirements, Helix RM (Perforce), Codebeamer, ReqView, and Modern Requirements for DevOps—are widely used for managing complex project requirements, and how do they compare in terms of capabilities like end-to-end traceability, version control, change management, collaboration workflows, integration with development and testing tools, reporting dashboards, compliance support, scalability, and ease of deployment for agile teams, product managers, and enterprise software engineering organizations?
