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Room for Improvement: IBM DOORS faces criticism due to its outdated user interface and steep learning curve.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

"We have different generations of all products. It lets us select and see unique attributes for each release or generation. You can use attributes to define a selection area to see which equipments are for the old versions and which ones are for the new versions. This inbuilt view is what I like in IBM Rational DOORS. So, for a database and a set of requirements, it will select and show unique attributes for a release or a generation."

"If people need to write specifications in the context of engineering then I think that this is the best solution on the market."

"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."

"This solution has always been very stable and doesn't really ever let us down."

"Over time, I have tried every other ARM tool out there for various customers and kept going back to Rational DOORS."

"The most valuable feature is the management verification and login."

"The most valuable feature of this solution is traceability. We can track every requirement, including what the stakeholder must do and component-level requirements."

"It has improved our ability to do traceability back to our initial requirements."

More IBM DOORS pros

"The most beneficial features of Polarion Requirements for traceability include the traceability function and also the historical and matchmaking or cross-referencing, which was very good."

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

"It is easier to produce documents using the platform."

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

"Its flexibility and APIs are the most valuable."

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

"I like the way this solution is structured."

"My company mainly utilizes the product for documenting internal standards, guidelines, and requirements. Currently, we're focusing on using it for internal purposes, but the vision is to expand its usage to include contract requirements and tracking functionalities. While we're not there yet, it has proven effective for managing our internal documentation needs."

More Polarion Requirements pros

Cons

"Both the performance and the price could be improved."

"Some users complain of a clunky interface, but DOORS NG which is planned to succeed DOORS over the next 5-10 years addresses these issues and is a good up and coming alternative to DOORS."

"The all-in-all service through Telelogic times was much better than since IBM took over."

"Not all Rational Team Concert operations are available from the web client. Certain operations, like creating streams or components, still require using the desktop application. They're not accessible through the web interface. And in my opinion, this limitation should be removed."

"Customer service suffered everytime Rational DOORS changed its organizational structure (i.e. from QSS to Telelogic to IBM)."

"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."

"The whole idea behind this solution is great but, the execution and the handling is old fashioned."

"It needs word processing captioning as well as references within a module."

More IBM DOORS cons

"The risk assessment functionality needs improvement, like FMEA risk management."

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

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

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

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

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

"Polarion Requirement needs to have a feature where we can track changes and compare documents. Currently, we do it manually."

"If we have more than one thousand work items in one live-book then it becomes almost unusable."

More Polarion Requirements cons

Pricing and Cost Advice

"The licensing costs for the product are quite high."

"IBM Rational DOORS is highly expensive."

"IBM is a bit too expensive in terms of pricing. Customers are paying a lot for the license, and the price is quite high for this kind of environment. It is quite high as compared to what we can get today with other solutions."

"It is expensive to onboard additional users."

"IBM DOORS is available at a reasonable price"

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

"Pricing can vary depending on the size of the organization and how contracts are negotiated."

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

More IBM DOORS pricing and cost advice

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

"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."

"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."

"Polarion Requirements is a little pricey."

"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."
