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."
"I like being able to sort and categorize the requirements and the exporting functions."
"The shell scripting is the solution's most valuable aspect."
"I like the way we can simply link requirements with one another and with test descriptions and then automatically produce reports that are required to show compliance to our customers. It is a combination of requirements management and reporting that I like, but I really have very little to do with the reporting part of it. I don't know how easy or hard it is to create those reports."
"Many of our defense customers give us the requirements in a DOOR file, so we can instantly import it, and in minutes we have the requirements and can begin the flow down to the various levels of the design as we work on it."
"Being able to track changes to requirements and being able to export is the solution's most valuable aspect."
"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."
"Customer Service: Excellent! IBM Rational DOORS team have always been quick to respond and knowledgeable about any issues I may have presented them."
"IBM Rational DOORS allows requirements to be efficiently and effectively tracked, traced, and managed throughout the project lifecycle."
 

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."
"I would like to see them improve in agile management the Scrum/Kanban Board to work with overseas team members."
"They need to provide users with information on what options would be best for their setup."
"Customer service suffered everytime Rational DOORS changed its organizational structure (i.e. from QSS to Telelogic to IBM)."
"Pricing is on the higher side because of multiple users who want to make use of the great functionality of tools."
"IBM DOORS should cover all engineering functions seamlessly, not just requirement engineering."
"Complexity, performance, openness are the three areas that can be improved. The IBM architecture and specifically Jazz looks more complex. There are a lot of servers. It's quite complicated. The search capabilities lack in IBM Rational DOORS Classic for customers who have a database with a requirement of more than 25,000 records. For example, you can search easily for a module, but it's really difficult to look for keywords through the whole database because all the modules are separated into small components, which makes the search quite complex. This is something that's really annoying because when we want to make an impact analysis, we would like to analyze the product globally. It's quite difficult to manage. The fact that you can interact externally with data makes it complex. The approach is complex and doesn't work as expected. For example, when I tried to experiment with exporting some records, the tool crashed, but I couldn't find out the root cause, that is, whether it happened because of Rational Windows or lack of memory. It was just crashing. Logs weren't very clear. IBM can try to use more recent technology for different aspects and make it easy. They can also provide free integration from DOORS Classic to DOORS. Currently, all the customization in Excel is lost, which makes it very complex. It would be a feature to make new versions compatible with features in the past versions."
"It can crash, but it doesn't happen too often."
"It needs word processing captioning as well as references within a module."
 

Pricing and Cost Advice

Information not available
"IBM DOORS is available at a reasonable price"
"I am not sure why it is so expensive, but one license will cost approximately $15,000 in US dollars."
"It's expensive."
"Licensing fees are billed annually and there is no support included with what I pay."
"It is expensive to onboard additional users."
"I would rate the pricing a seven out of ten, with one being very affordable and ten being quite expensive."
"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."
