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

"3SL Cradle enabled my current and former organizations to be champions of requiring and providing bi-directional traceability to all relevant data, from cradle to grave -- the entire project lifecycle -- due to the tool’s ability to be customized with ease and ability to produce products that builds confidence in project stakeholders."

"3SL Cradle's most valuable feature is its flexibility in managing all your needs immediately."

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

"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."

"I like the way this solution is structured."

"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."

"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."

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

"We worked with the web interface."

More Polarion Requirements pros

Cons

"3SL Cradle could be improved with better support for SysML functionalities."

"Cradle provides around 15 modeling notations (e.g. Data Flow Diagrams, State Transition Diagrams, Use Case Diagram, etc.); however, SysML and DoDAF are not included."

"If we have more than one thousand work items in one live-book then it becomes almost unusable."

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

"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."

"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 usability of the solution should also be improved."

"It is not a stable solution, as we had issues with shared licenses."

Pricing and Cost Advice

Information not available

"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."

"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."

"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."
