IBM DOORS and Polarion Requirements are established requirement management tools within the tech industry. Polarion is perceived to have the upper hand due to its ease of use and integration capabilities, offering higher value despite similar costs to IBM DOORS.
Features: IBM DOORS offers extensive customization through DXL scripting, allowing tailored process flows and integration with engineering tools. It provides detailed traceability, impact analysis, and configuration management. Polarion is known for traceability, seamless integration, and collaboration support, which is ideal for dynamic environments and offers consistency across requirements.
Room for Improvement: IBM DOORS presents a steep learning curve and complex integration issues with newer tools. Polarion's interface can be cumbersome, and its bulk editing and document review processes need enhancement. Users also desire more robust collaboration tools in Polarion.
Ease of Deployment and Customer Service: IBM DOORS mainly supports on-premises deployments with hybrid options, while Polarion offers public and private cloud options, easing modern IT integration. IBM's customer service has improved but can be inconsistent, whereas Polarion benefits from stable support, fostering user confidence.

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.
