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'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."
"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 program is very stable."
"Over time, I have tried every other ARM tool out there for various customers and kept going back to Rational DOORS."
"The products developed in our company that started with DOORS requirements in the late 90s are now a one billion dollar annual revenue product line."
"The most valuable features include traceability, configuration management, and user access."
"Rational DOORS' most valuable feature is that you can write any kind of requirement you want."
"Compared to other tools that I have used over the past 20 years, DOORS is the best of the best."
"The most valuable feature of IBM Rational DOORS is the full requirements development and testing."
 

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."
"The whole idea behind this solution is great but, the execution and the handling is old fashioned."
"It can crash, but it doesn't happen too often."
"Enhancing security measures, particularly when handling multiple projects simultaneously, would be beneficial to prevent data loss within DOORS."
"The kind of dashboard is not very convenient."
"It would be nice if it could be scaled-down so that it could be installed and implemented without much learning or training."
"It needs word processing captioning as well as references within a module."
"One of the things that many people complain about is it's hard to manage attributes. For example, tables or figures. This is something that can be improved."
"Both the performance and the price could be improved."
 

Pricing and Cost Advice

Information not available
"Pricing can vary depending on the size of the organization and how contracts are negotiated."
"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."
"I would rate the pricing a seven out of ten, with one being very affordable and ten being quite expensive."
"It's expensive."
"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."
"I am not sure why it is so expensive, but one license will cost approximately $15,000 in US dollars."
"IBM DOORS is available at a reasonable price"
