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Room for Improvement: IBM DOORS is criticized for its outdated design and sluggish remote performance.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

"It's a very interesting tool. I like that it's simple. You have to create your document, add your templates, and have your headings and definitions, and it's done. You must attribute the discipline and fill out the comment field for requirements. It also provides you with unique IDs for each requirement. I like that it never duplicates IDs."

"DOORS can help you to standardise, minimise mistakes and effort needed to achieve your goal, which can lead in reducing the cost of your development, validation and verification of your product."

"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."

"I really like the customization that can be done using the DOORS Extension Language (DXL)."

"I really enjoyed the API."

"IBM Rational DOORS has helped our organization because of the sense of configuration baseline; with it, we can create and freeze baselines, put them on configuration control, and then use it as evidence."

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

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

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 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."

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

"In my opinion, Polarion Requirements' most beneficial feature is the ability to manage specifications within a work-like document that functions as a work item. Its collaboration features have worked very well and have been very useful. We can easily exchange information with the testing team, the business, and with DevOps."

"Its flexibility and APIs are the most valuable."

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

"I like the way this solution is structured."

More Polarion Requirements pros

Cons

"One thing that I would like to see is a lower-cost version of it that we could use for smaller projects. Sometimes, we do projects for commercial customers who would benefit from something like DOORS, but it's just so expensive. It's just a monster, so a lower-cost version would be the thing that we'd like to see."

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

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

"Complexity, performance, openness are the three areas that can be improved. The IBM architecture and specifically Jazz looks more complex. There are a lot of servers. It's quite complicated. The search capabilities lack in IBM Rational DOORS Classic for customers who have a database with a requirement of more than 25,000 records. For example, you can search easily for a module, but it's really difficult to look for keywords through the whole database because all the modules are separated into small components, which makes the search quite complex. This is something that's really annoying because when we want to make an impact analysis, we would like to analyze the product globally. It's quite difficult to manage. The fact that you can interact externally with data makes it complex. The approach is complex and doesn't work as expected. For example, when I tried to experiment with exporting some records, the tool crashed, but I couldn't find out the root cause, that is, whether it happened because of Rational Windows or lack of memory. It was just crashing. Logs weren't very clear. IBM can try to use more recent technology for different aspects and make it easy. They can also provide free integration from DOORS Classic to DOORS. Currently, all the customization in Excel is lost, which makes it very complex. It would be a feature to make new versions compatible with features in the past versions."

"The low performance of the solution is probably because it is quite an old tool."

"It can crash, but it doesn't happen too often."

"The images are not clear. We have to use them as OLE objects. And in the testing part, I'm not sure how to link it with it. This is my main concern."

"It would be helpful if Microsoft provided a more user-friendly interface for updating and querying updates. Additionally, if there was a way for users to notify developers of any changes in requirements, it would allow for faster and more efficient updates to the solution's architecture. This could be in the form of a notification system that alerts developers of any changes that need to be made. Additionally, the solution is document-driven and it should be more digital."

More IBM DOORS cons

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

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

"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."

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

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

"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."

"Its user interface could be more user friendly. In addition, a lot of features are missing for test management. It should have the test case ordering feature."

More Polarion Requirements cons

Pricing and Cost Advice

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

"IBM DOORS is available at a reasonable price"

"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."

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

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

"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."

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

"It's expensive."

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."

"Polarion Requirements is a little pricey."

"The product's price is high."

"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."

"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."
