IBM DOORS and Polarion Requirements are both leaders in the requirements management software category. While IBM DOORS offers strong customization options, Polarion Requirements edges ahead with its emphasis on collaboration and integration.
Features: IBM DOORS offers extensive customization through its DXL scripting language, allowing tailored solutions for complex requirements management. It excels in traceability and integrates with numerous engineering tools. Polarion Requirements stands out for seamless collaboration and document management, enabled by its strong integration using REST and open APIs, which suits distributed teams well.
Room for Improvement: IBM DOORS faces challenges such as a steep learning curve and complex interfaces, and it encounters integration issues due to its proprietary database engine. It lacks support for agile processes. Polarion Requirements could improve its bulk editing capabilities and user interface to enhance usability. Enhancements in integration and risk management features are also needed for better performance.
Ease of Deployment and Customer Service: IBM DOORS primarily supports on-premises deployment with some hybrid cloud options. Its customer service has shown varied performance, with criticism directed at response times and advanced feature support. Polarion Requirements offers flexible deployment including public and private cloud options, with customer support generally commended for being responsive and helpful.
Pricing and ROI: IBM DOORS is noted for being expensive, especially with multiple licenses and extensions. The cost is justified for large-scale projects in regulated environments, promising significant ROI. Polarion Requirements offers a flexible pricing model based on user roles, providing a cost-effective solution for complex projects requiring collaborative features. Both promise substantial ROI, yet Polarion's pricing flexibility is beneficial for smaller teams.
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.
We monitor all Application Requirements Management reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
