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

"The most valuable feature for me is the ability to enter data into one table, or context, and link it across modules."
"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 is a mature product that is stable."
"Requirements development, and doing everything from functional requirements to system requirements, means we can verify that there are no orphan or childless requirements, which ensure full traceability in a short amount of time using the available tools."
"IBM DOORS has a well-refined ASPICE template"
"The product was used to better track and structure requirements we were developing for a new product that was to be integrated into an existing system with its own requirements."
"IBM Rational DOORS is good for privacy, it's good for the management of software requirements, and also for keeping everything organized."
"Over the years supporting requirements management, I have participated in many trade studies where tools were evaluated, and DOORS won most every time."
"We worked with the web interface."
"I like the way this solution is structured."
"I would say there is value in how powerful, configurable, and user-friendly it is."
"The biggest improvement would be in the transparency we have now, as we have very complex products and make whole systems with difficult and diverse areas such as hardware, software, mechanical and printing, and to get the overview of all the requirements into a system at that sizing is the main advantage we have in the organization now."

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

Cons

"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."
"Rational DOORS' most valuable feature is that you can write any kind of requirement you want."
"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."
"Getting started with DOORS Administration, how to setup a project, how to maintain it, and how to get started with DXL are all areas that need quite a bit of experience to master."
"The customer must also have the tool to import the changes and accept them as a part of the review."
"Its primary failing is that Rational made the cost of the product and learning to use the product so expensive that very few people or companies were willing to absorb that overhead without a guarantee of revenue to compensate for it."
"It is complex, doesn't work as expected, and isn't easy to illustrate."
"It can crash, but it doesn't happen too often."
"The areas of Polarion Requirements that have room for improvement include usability, and the user interface, which was a little bit poor."
"If we have more than one thousand work items in one live-book then it becomes almost unusable."
"The platform's review process for the documents could be better."
"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."
"Its user interface could be more user friendly. In addition, a lot of features are missing for test management."
"I would rate this product a two out of 10."
"One thing to consider is increased flexibility in terms of workflow configuration."
"If we have more than one thousand work items in one live-book then it becomes almost unusable."
 

Pricing and Cost Advice

"IBM DOORS is available at a reasonable price"
"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."
"Pricing can vary depending on the size of the organization and how contracts are negotiated."
"Licensing fees are billed annually and there is no support included with what I pay."
"The licensing cost is too high."
"It is expensive to onboard additional users."
"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 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 product's price is high."
"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."
"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."
