The most valuable features are the versioning of requirements and the possibility to reuse them.
IBM DOORS Next offers efficient linking via Link by Attribute, valuable versioning, and reusable requirements. It supports large user bases with a scalable system featuring baselines, links, and components. A traceability matrix enhances requirement management, but usage can be hampered by server or network issues. Migration from DOORS poses challenges, and intuitiveness is lacking for occasional users. Data storage, reporting, and integration APIs also need improvement.
