Amol Dumbre - PeerSpot reviewer
Software Manager at Forvia
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

"It is very customizable and easy to scale."
"It has improved our ability to do traceability back to our initial requirements."
"The program is very stable."
"The platform's traceability capabilities are invaluable. They provide a solid foundation for certification processes and manage requirement changes across project lifecycles."
"This solution has always been very stable and doesn't really ever let us down."
"The most valuable feature for me is the ability to enter data into one table, or context, and link it across modules."
"The most valuable feature for me is the ability to enter data into one table, or context, and link it across modules."
"Rational DOORS' most valuable feature is that you can write any kind of requirement you want."
"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 like the way this solution is structured."
"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."
"I like the way this solution is structured."
"I would say there is value in how powerful, configurable, and user-friendly it is."
"The solution is especially great for organizing folders effectively."
"Polarion Requirements' most valuable features are link tracing, book entry, and sequence training features."
 

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."
"There needs to be quicker access to tech support. When I have a two minute question that takes two minutes to answer, it shouldn't take me 45 minutes and/or a few days of callbacks to get to the right technical support person. It's unnecessary and frustrating for the user."
"It is complex, doesn't work as expected, and isn't easy to illustrate."
"Upon losing connection to VPN/internet, DOORS can lose the content written and this requires it to be redone."
"The most difficult feature of DOORS is how it creates "DOORS tables" from tables that are imported from a Word document."
"It can crash, but it doesn't happen too often."
"It is complicated sometimes, such as the logic about updating, moving from one server version to another, and the communication between restricted and non-restricted servers."
"The web application DOORS Web Access doesn't have the same functionality as the standard client, so it's not a real substitute."
"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."
"Its user interface could be more user friendly. In addition, a lot of features are missing for test management."
"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."
"One thing to consider is increased flexibility in terms of workflow configuration."
"Integration can be a little tricky if you're not aware of basic computer science or programming language."
"If we have more than one thousand work items in one live-book then it becomes almost unusable."
"The usability of the solution should also be improved."
"If we have more than one thousand work items in one live-book then it becomes almost unusable."
 

Pricing and Cost Advice

"I think it's expensive because you have to pay for the licenses to IBM and all that and maintain them."
"I would rate the pricing a seven out of ten, with one being very affordable and ten being quite expensive."
"It's expensive."
"Licensing fees are billed annually and there is no support included with what I pay."
"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."
"It is expensive to onboard additional users."
"IBM Rational DOORS is highly expensive."
"IBM DOORS is available at a reasonable price"
"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."
"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."
"I rate the solution's pricing a seven out of ten."
