Executive SummaryUpdated on Jun 3, 2026

IBM DOORS and Polarion Requirements compete in the requirements management tools category. Polarion Requirements has a slight advantage due to its ease of integration and flexible deployment options, appealing to a broader range of project needs.

Features: IBM DOORS offers robust traceability, allowing links between requirements and test descriptions, and supports customization via Dynamic Extension Language (DXL). It is suitable for large-scale requirements management with complex baselining needs. Polarion Requirements provides document management, real-time collaboration, and version control, integrating well with tools like Jira, which enhances its usability for cross-functional teams.

Room for Improvement: IBM DOORS is criticized for its outdated design and sluggish remote performance. New users find its interface unintuitive and integration with external tools challenging. Polarion Requirements has a non-intuitive interface and struggles with requirements management across project lifecycles, necessitating customization for improved usability.

Ease of Deployment and Customer Service: IBM DOORS primarily supports on-premise deployment, lacking cloud flexibility. Customer service receives mixed reviews, with slow resolution times reported. Polarion Requirements offers both on-premise and cloud options, generally easier to customize, though complexity arises with integration. Both receive varying feedback on customer service efficiency.

Pricing and ROI: IBM DOORS is considered expensive, with licensing and operational costs concerns. It delivers significant ROI in large projects due to extensive features. Polarion Requirements also has a high price but offers a flexible licensing model, appealing to diverse user needs. While both tools are valuable for large projects, their pricing may deter smaller businesses.

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

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

"I am able to create a traceability and impact analysis report of a set of 20+ documents in minutes, and then use the tool to help verify that the data is accurate."

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

"It allows you to manipulate the software to your liking, as it's very customizable and can be as powerful as you want it to be."

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

"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."

"I would say that the best feature of the solution is that since everything is in one place, and if you make any changes, then they are recorded or tracked."

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."

"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."

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

"Polarion Requirements' most valuable features are link tracing, book entry, and sequence training features."

"Its flexibility and APIs are the most valuable."

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

"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."

"We worked with the web interface."

More Polarion Requirements pros

Cons

"It could be more user-friendly. It's not a beautiful tool. The user interface is gray. It has only lists inside, and it's horrible when you want to add tables. It's tough to add tables and manage them. It also becomes difficult when you want to add images."

"It used to be very clunky."

"It is complex, doesn't work as expected, and isn't easy to illustrate."

"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."

"One issue with the 9.6 version is the new feature of resizing and positioning the main DOORS explorer window and opening the last opened modules during start."

"Clean specification generation has become more difficult under IBM’s direction, than it was under QSS or Telelogic."

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

"The most difficult feature of DOORS is how it creates "DOORS tables" from tables that are imported from a Word document."

More IBM DOORS cons

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

"The user configuration had some issues; you need to know all the details, so it's not really friendly for those who are not IT savvy."

"In my opinion, the main area for improvement in Polarion Requirements is its user interface. It should be easier for engineers to understand how it works, as many features are not very easily understandable for end-users."

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

"I would rate this product a two out of 10."

"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."

"The platform's review process for the documents could be better."

More Polarion Requirements cons

Pricing and Cost Advice

"IBM Rational DOORS is highly expensive."

"It is expensive to onboard additional users."

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

"It's expensive."

"IBM DOORS is available at a reasonable price"

"The licensing cost is too high."

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

"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."

More IBM DOORS pricing and cost advice

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

"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."

"The product's price is high."

"Polarion Requirements is a little pricey."

"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."
