IBM DOORS and Polarion Requirements are both leading tools in requirements management. Based on feature set and flexibility, Polarion Requirements has the edge with its user-friendly cloud deployment and superior integration capabilities.
Features: IBM DOORS offers advanced customization through DXL scripting, robust traceability, and sophisticated configuration management. It excels in complex requirements modeling, impact analysis, and user-defined traceability. Polarion Requirements, however, focuses on real-time collaboration, seamless document management, and easy integration with various workflow tools, beneficial for collaborative teams.
Room for Improvement: IBM DOORS faces criticism due to its outdated user interface and steep learning curve. It requires improvements in its integration features and database interaction. Polarion Requirements needs more intuitive bulk editing and improved analytics features. Both could benefit from cost-related adjustments, though Polarion could also refine its review processes and user interface.
Ease of Deployment and Customer Service: IBM DOORS primarily offers an on-premises deployment, reflecting a traditional and complex setup. Its customer service has improved but needs further enhancement for advanced feature support. Polarion Requirements stands out with flexible cloud deployment options, making it more accessible. It has a strong reputation for customer support, albeit with a need for faster response times.
Pricing and ROI: Both IBM DOORS and Polarion Requirements are costly, appealing to large organizations seeking comprehensive functionalities. IBM DOORS delivers significant ROI for projects where customization and traceability are key, while Polarion Requirements provides high ROI through real-time collaboration and seamless integration capabilities, ensuring their premium pricing is matched by robust functionalities.

IBM Engineering Requirements Management DOORS (DOORS) is a Requirements Management (RM) software designed to help organizations manage engineering project requirements throughout the development lifecycle. It provides a central location for capturing, defining, and organizing project requirements, facilitating communication and collaboration among stakeholders like engineers, system designers, and customers. Key features include requirements traceability, version control, and impact analysis, ensuring effective implementation and testing. DOORS improves efficiency, enhances communication, reduces risks, and supports better decision-making through clear visibility into requirements. Compared to its newer, web-based counterpart DOORS Next, the mature DOORS 9 offers a wider range of features with a traditional user interface but lacks web-based functionality and modern integration with IBM Engineering Lifecycle Management (ELM) tools.
