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.

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."
"The platform's traceability capabilities are invaluable. They provide a solid foundation for certification processes and manage requirement changes across project lifecycles."
"The most valuable features include traceability, configuration management, and user access."
"We have different generations of all products. It lets us select and see unique attributes for each release or generation. You can use attributes to define a selection area to see which equipments are for the old versions and which ones are for the new versions. This inbuilt view is what I like in IBM Rational DOORS. So, for a database and a set of requirements, it will select and show unique attributes for a release or a generation."
"If you have a high number of requirements to manage and if there is a need to sustain these baseline of requirements for a couple of years, it is the right solution for you."
"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 solution is stable."
"It is a stable solution."
"It enables us to manage our customers' requirements effectively and efficiently."
 

Cons

"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."
"3SL Cradle could be improved with better support for SysML functionalities."
"Overall, the user experience should be enhanced."
"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."
"The most difficult feature of DOORS is how it creates "DOORS tables" from tables that are imported from a Word document."
"One issue with the 9.6 version is the new feature of resizing and positioning the main DOORS explorer window and opening the last opened modules during start."
"The interface needs an area to be able to type your query and actually be able to find them."
"I would like to see them improve in agile management the Scrum/Kanban Board to work with overseas team members."
"The all-in-all service through Telelogic times was much better than since IBM took over."
"The only gap I have identified is in code-level coverage reporting."
 

Pricing and Cost Advice

Information not available
"I think it's expensive because you have to pay for the licenses to IBM and all that and maintain them."
"The licensing cost is too high."
"Licensing fees are billed annually and there is no support included with what I pay."
"It's expensive."
"The licensing costs for the product are quite high."
"It is expensive to onboard additional users."
"Pricing can vary depending on the size of the organization and how contracts are negotiated."
"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."
