Executive SummaryUpdated on Feb 8, 2026

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Room for Improvement: IBM DOORS faces criticism due to its outdated user interface and steep learning curve.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.

Integrated lifecycle management has supported global A‑SPICE projects and custom reporting

I believe the toolchain currently covers all of our requirements. Even for A-SPICE and related requirements, I can add attributes and manage things effectively because the tool is highly customizable. I can continue updating things and managing different processes. The only gap I have identified is in code-level coverage reporting. I have coverage traceability from IBM DOORS through the architecture and design, but I am unable to demonstrate code-level coverage reporting. That reporting capability would be helpful. Testing is covered very well through IBM Test Manager. The traceability to code is something I feel there may be certain gaps in, though I may not be fully aware of all capabilities since my role is different and I primarily receive reports rather than being an end user. Regarding the traceability feature, I am not an end user but rather receive reports from my team, so my perspective is limited.

Comprehensive traceability has supported regulated projects but review workflows still need improvement

The ability to manage requirements through the whole project life is somewhat unclear. We are not using the ability to track all requirements through the whole project life for analytics very much. We have a way to easily find all the requirements of a complex product, even if they are spread over different Polarion Requirements projects. We do not have any issues in that area, but we are not really using the analytics part of Polarion Requirements. I am satisfied with the integration capabilities for Polarion Requirements, but it depends. We encountered a lot of issues with the integration with Enterprise Architect. We were in contact with Lemon Tree company, which provides support for that integration, but we eventually decided to develop our own plugins for Polarion Requirements. That is unfortunate, but we are not really happy with their implementation. There are things that are going really well, but alongside this, there are also things that are not yet implemented, which is quite annoying for us. The main point for improvement or lack of functions that I would like to address in Polarion Requirements is really about the review process, which is a bit too limited. When we are developing complex products, we have to review big life documents or a set of work items, but there are a lot of issues with that. For example, very simple things: if you select a word and not a space in the document, you are not able to add comments, and it is not user-friendly. If you know that you have to put the cursor and not select the word, that is something people can live with, but for newcomers, it is frustrating. They will ask questions such as 'I cannot add a comment about this word' or for a selection of text. That is something annoying. You can do that in a simple Word document, but not in Polarion Requirements. Also, the ability to review a table or generated dynamic content is not possible in Polarion Requirements. For example, if you generate automatically a list of tests, you cannot click on the second one; you can only click at the beginning of the generated sections. I am somewhat satisfied with Polarion Requirements' functionality, but I feel a lack of certain functions regarding the review, which is a bit too limited. The review process is the main pain point for me, especially since we are in a highly regulated environment where reviews are crucial for us.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It enables us to manage our customers' requirements effectively and efficiently."

"When you install DOORS locally, you have the flexibility to do what you want with the solution. You can add functionality and do many things that you can't do with other tools or do well enough to satisfy your users' requirements."

"It is a stable solution."

"When you install DOORS locally, you have the flexibility to do what you want with the solution, you can add functionality and do many things that you can't do with other tools or do well enough to satisfy your users' requirements."

"Compared to other tools that I have used over the past 20 years, DOORS is the best of the best."

"What I like about DOORS is baselines, it's easy and I use the capability of multiple users. The traceability or links between different levels are very nice. Additionally, it is used by all of our suppliers, which brings us commonality."

"The most valuable features include traceability, configuration management, and user access."

"DOORS improved the way requirements were shared across the organization, and helped implement reuse strategy."

More IBM DOORS pros

"The solution is especially great for organizing folders effectively."

"We can easily customize it because of the web services and open APIs. Also, the APIs are available. We integrated Polarion with one of Siemens' products, Teamcenter, which is especially useful for automotive industries. There is an open API for integration with Jira as well, so for me, customization is a strong point."

"The biggest improvement would be in the transparency we have now, as we have very complex products and make whole systems with difficult and diverse areas such as hardware, software, mechanical and printing, and to get the overview of all the requirements into a system at that sizing is the main advantage we have in the organization now."

"Polarion Requirements is a really great product despite the limitations I mentioned and the price which is getting more and more expensive."

"The biggest improvement would be in the transparency we have now. We have very complex products. We make whole systems with difficult and diverse areas such as hardware, software, mechanical and printing, etc. To get the overview of all the requirements into a system, at that sizing, is the main advantage we have in the organization now."

"We worked with the web interface."

"I would say there is value in how powerful, configurable, and user-friendly it is."

"We use the product to review and assign requirements we receive from customers."

More Polarion Requirements pros

Cons

"Getting started with DOORS Administration, how to setup a project, how to maintain it, and how to get started with DXL are all areas that need quite a bit of experience to master."

"The Rational DOORS client is terribly slow if you are not on-site with the server."

"The user interface for the Change Proposal System could be improved."

"The HMI is difficult to use and the user interface should be better."

"The testing part needs to be improved, but they have too much legacy to move to the latest IBM versions."

"It would be nice if it could be scaled-down so that it could be installed and implemented without much learning or training."

"The web application DOORS Web Access doesn't have the same functionality as the standard client, so it's not a real substitute. For example, web Access only provides writing requirements, but you can't do much more with it."

"I would like to see them improve in agile management the Scrum/Kanban Board to work with overseas team members."

More IBM DOORS cons

"I am somewhat satisfied with Polarion Requirements' functionality, but I feel a lack of certain functions regarding the review, which is a bit too limited."

"We encountered numerous challenges, such as issues with requirements, project management, timing, and planning. The main problem with Polarion at the outset, I believe, was our limited understanding of the planning phase. During that time, we were more focused on change management related to requirements. Recognizing the importance of planning has been a key realization for us. Another mistake we made was not comprehending the need to document these requirements to manage all the work items effectively. Now, we understand the significance of this documentation. As a result of these insights, we have started to see a growing number of competitors from Polarion in this field. One potential improvement could be enabling Polarion to export work items not just to Microsoft Office but also to other office tools."

"The usability of the solution should also be improved."

"Its user interface could be more user friendly. In addition, a lot of features are missing for test management."

"One thing to consider is increased flexibility in terms of workflow configuration."

"The one thing I would mention is the license policy is a little bit difficult."

"The areas of Polarion Requirements that have room for improvement include usability, and the user interface, which was a little bit poor."

"It is not a stable solution, as we had issues with shared licenses."

More Polarion Requirements cons

Pricing and Cost Advice

"I would rate the pricing a seven out of ten, with one being very affordable and ten being quite expensive."

"Licensing fees are billed annually and there is no support included with what I pay."

"I don't personally know what the numbers are. I just know that one of the reasons we've limited it to three seats is a function of cost."

"We have to pay for a license. I think it's a one-time payment as my company hasn't notified me about more charges. I don't think it's expensive for large corporations, but it will be costly for an average person."

"It is expensive to onboard additional users."

"I am not sure why it is so expensive, but one license will cost approximately $15,000 in US dollars."

"I think it's expensive because you have to pay for the licenses to IBM and all that and maintain them."

"The licensing cost is too high."

More IBM DOORS pricing and cost advice

"Polarion Requirements is a little pricey."

"It is expensive but not for what it is. It is just the right price for what it is. Its price is also similar to other solutions."

"The product's price is high."

"I believe the cost is subjective. It seems a bit pricey, but it depends on your perspective. To provide some context, I compared the prices with GitLab and Jira. Unfortunately, I couldn't find Jira's prices. However, GitLab costs around 40 euros, and DeepLab, which I recently discovered, also falls in a similar price range. I'm not sure about DeepLab's features or interface improvements, as they might have been implementing requirements management over the past six months. In contrast, Polarion costs around 50 to 60 euros based on the 2021 prices I have. While it may seem a bit expensive, it's worth considering whether the additional investment, perhaps around 68 euros per user, is justified. It might appear costly at first glance, but it's essential to acknowledge that it can greatly streamline your work processes."

"The pricing model is flexible. You don't have to pay for the full functionalities. And it's a one-time investment for the licenses. You purchase what you need and then can work with that."

"I rate the solution's pricing a seven out of ten."

Overview

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.
