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 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 product was used to better track and structure requirements we were developing for a new product that was to be integrated into an existing system with its own requirements."
"Requirements development, and doing everything from functional requirements to system requirements, means we can verify that there are no orphan or childless requirements, which ensure full traceability in a short amount of time using the available tools."
"It helps us to standardize the way our globally distributed teams are now collaborating and managing the different artifacts."
"I really enjoyed the API."
"Compared to other tools that I have used over the past 20 years, DOORS is the best of the best."
"The most valuable features include traceability, configuration management, and user access."
"I like being able to sort and categorize the requirements and the exporting functions."
 

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."
"It can crash, but it doesn't happen too often."
"The solution should be more compatible with thin clients"
"The whole idea behind this solution is great but, the execution and the handling is old fashioned."
"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 needs word processing captioning as well as references within a module."
"It would have been ok ten years ago, but we are used to having better tools now."
"IBM DOORS should cover all engineering functions seamlessly, not just requirement engineering."
"The performance could be improved. It doesn't run as smoothly as it could."
 

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."
"I would rate the pricing a seven out of ten, with one being very affordable and ten being quite expensive."
"It's expensive."
"I am not sure why it is so expensive, but one license will cost approximately $15,000 in US dollars."
"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."
"IBM Rational DOORS is highly expensive."
"The licensing costs for the product are quite high."
"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."
