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.

Positive impact on traceability while user interface and setup require improvement
The areas of Polarion Requirements that have room for improvement include usability, and the user interface, which was a little bit poor. 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. Someone who has a good IT background would be able to use it, but a regular person who just knows more or has always been dealing with Microsoft Word might find it difficult to use that system. Users need skills to work with this solution and also need to have some foundation of why those technical integrations and cross-referencing have to be done in such a way through systematization, which makes it difficult and not straightforward through the visibility of the user interface.

Quotes from Members

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

Pros

"The traceability matrix in DOORS improved our project outcomes. It helps ensure coverage of requirements at different levels, from user requirements to software requirements to test requirements."
"The most valuable feature of this solution is traceability. We can track every requirement, including what the stakeholder must do and component-level requirements."
"This product can help improve how your organization proceeds through solution development."
"The most valuable feature is the management verification and login."
"It is a stable solution."
"I really enjoyed the API."
"Very customizable and can be as powerful as you want it to be."
"Traceability on requirements for a huge project in an organization is a big gain."
More IBM DOORS pros
"I would say there is value in how powerful, configurable, and user-friendly it is."
"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."
"I like the way this solution is structured."
"A valuable feature from my side would be the comparison corporization."
"The solution is especially great for organizing folders effectively."
"We worked with the web interface."
"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 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."
More Polarion Requirements pros
 

Cons

"The problem is that because the GUI is so bad, you either have to spend a lot of money customizing the interface yourself, or a lot of money on training."
"The performance could be improved. It doesn't run as smoothly as it could."
"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."
"IBM DOORS should cover all engineering functions seamlessly, not just requirement engineering."
"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 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."
"There are problems with communicating between DOORS and Microsoft Office."
"The interface needs an area to be able to type your query and actually be able to find them."
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."
"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."
"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 risk assessment functionality needs improvement, like FMEA risk management."
"Polarion Requirement needs to have a feature where we can track changes and compare documents. Currently, we do it manually."
"One thing to consider is increased flexibility in terms of workflow configuration."
"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 usability of the solution should also be improved."
More Polarion Requirements cons
 

Pricing and Cost Advice

"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."
"The licensing costs for the product are quite high."
"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."
"The licensing cost is too high."
"It's expensive."
More IBM DOORS pricing and cost advice
"The product's price is high."
"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."
"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."
"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."
