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Room for Improvement: IBM DOORS is criticized for its outdated design and sluggish remote performance.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.

Project Manager at a manufacturing company with 51-200 employees

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."

"Starting to use the solution is pretty straightforward. There isn't too much of a learning curve."

"By learning how to write reusable DXL, I've been able to write a single script that can then be plugged into all DOORS clients at my company, meaning if I can save one person 1 hour we can then multiply that by hundreds (if not thousands) of system engineers which equates to quite a lot of time and money saved."

"The most valuable feature of this solution is traceability; we can trace every requirement, including what the stakeholder must do and component-level requirements, and we can trace them easily, which is very beneficial."

"Rational DOORS can be an excellent requirements management tool, but only if all users are on-site with the server, all users are trained in how to use the basic features of the tool, and there is an experienced Rational DOORS admin and DXL developer that can support users and create customizations and extensions."

"Over the years supporting requirements management, I have participated in many trade studies where tools were evaluated, and DOORS won most every time."

"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."

"DOORS is a high-quality, high-end system-requirements development tool."

More IBM DOORS pros

"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."

"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."

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

"We worked with the web interface."

"A valuable feature from my side would be the comparison corporization."

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

"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."

More Polarion Requirements pros

Cons

"It used to be very clunky."

"Upon losing connection to VPN/internet, DOORS can lose the content written and this requires it to be redone."

"Pricing is on the higher side because of multiple users who want to make use of the great functionality of tools."

"I think there is probably room to improve by offering free training."

"From my experience, I would not recommend IBM DOORS to others now."

"The software and GUI is very outdated."

"The solution should be more compatible with thin clients"

"The software is very dated and old. It's hard to get people to use it because the GUI looks like something from one of those giant Mac computers."

More IBM DOORS cons

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

"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."

"The one thing I would mention is the license policy is a little bit difficult. For different roles, you will need different license models. That seems a little bit difficult for us. Especially when you introduce such a complex system, you want to know the right way is to do licensing. It's not clear what that best way would be. The solution will be here for a long time, and I just think it could be more clear."

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

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

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

"It is stable enough but if you would like to work with more requirement objects, then you will get timeouts."

"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."

Pricing and Cost Advice

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

"The licensing cost is too high."

"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's 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."

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

"IBM Rational DOORS is highly expensive."

"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."

More IBM DOORS pricing and cost advice

"The product's price is high."

"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 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 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."

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