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.

Pros

"3SL Cradle's most valuable feature is its flexibility in managing all your needs immediately."
"3SL Cradle's most valuable feature is its flexibility in managing all your needs immediately."
"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."
"The most valuable feature is the management verification and login."
"The platform's traceability capabilities are invaluable. They provide a solid foundation for certification processes and manage requirement changes across project lifecycles."
"Traceability on requirements for a huge project in an organization is a big gain."
"Starting to use the solution is pretty straightforward. There isn't too much of a learning curve."
"We have different generations of all products; it lets us select and see unique attributes for each release or generation, and 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."
"IBM Rational DOORS allows requirements to be efficiently and effectively tracked, traced, and managed throughout the project lifecycle."
"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."
"What I like about DOORS is baselines, it's easy and I use the capability of multiple users. The traceability or links between different levels are very nice. Additionally, it is used by all of our suppliers, which brings us commonality."
 

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."
"3SL Cradle could be improved with better support for SysML functionalities."
"DOORS weakness is in the interface with the outside world, as the database is not standard, data cannot be easily managed by other tools."
"The user interface for the Change Proposal System could be improved."
"One thing that I would like to see is a lower-cost version of it that we could use for smaller projects. Sometimes, we do projects for commercial customers who would benefit from something like DOORS, but it's just so expensive. It's just a monster, so a lower-cost version would be the thing that we'd like to see."
"The low performance of the solution is probably because it is quite an old tool."
"Overall, the user experience should be enhanced."
"The interface needs an area to be able to type your query and actually be able to find them."
"The solution should be more compatible with thin clients"
"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."
 

Pricing and Cost Advice

Information not available
"The licensing costs for the product are quite high."
"It is expensive to onboard additional users."
"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."
"I am not sure why it is so expensive, but one license will cost approximately $15,000 in US dollars."
"It's expensive."
"Pricing can vary depending on the size of the organization and how contracts are negotiated."
"IBM is a bit too expensive in terms of pricing. Customers are paying a lot for the license, and the price is quite high for this kind of environment. It is quite high as compared to what we can get today with other solutions."
"Licensing fees are billed annually and there is no support included with what I pay."
