IBM Rational DOORS (Dynamic Object-Oriented Requirements System) is a requirements engineering tool that helps organizations capture and manage requirements for software and systems development projects. It enables teams to capture, trace and manage requirements and design components for these projects. With Rational DOORS, teams can easily define, analyze and share requirements, ensuring that all stakeholders have visibility into the requirements and that these are properly managed throughout the product development lifecycle. This helps to ensure that all requirements are met, that project deadlines are met, and that the end product meets customer expectations. Rational DOORS also provides powerful reporting capabilities, allowing teams to quickly and easily generate reports of requirements and traceability links.
