What is our primary use case?
We use it to manage requirements. For the defense projects, we basically do a waterfall design methodology. So, we input the customer's requirements at the top level, and we flow down through all of the design requirements and the testing requirements. We keep it all managed through DOORS.
How has it helped my organization?
Many of our defense customers give us the requirements in a DOOR file, so we can instantly import it. Nobody has to sit there playing with spreadsheets or anything else. In minutes, we have the requirements, and we can begin the flow down to the various levels of the design as we work on it. The thing that we like about it is the fact that it's compatible with what our defense and also space customers use.
What is most valuable?
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.
What needs improvement?
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.
For how long have I used the solution?
I have been using this solution on and off for about eight years.
What do I think about the stability of the solution?
It is incredibly stable. We've never had a problem with its stability.
What do I think about the scalability of the solution?
In the projects we've done, we've never bumped into a limit where we needed to do anything to accommodate the project. It just works. So, we've never had to scale it.
In terms of the number of users, we're limited to about three people who use it, and they're all hardware and software engineers.
It is being used extensively. We use it every day. We could apply it to other things. If there was a lower-cost version of it, we would probably use it more widely through our projects, so that's really more a function of the cost of the product than the usability of it.
How are customer service and technical support?
I didn't have any encounters with them.
Which solution did I use previously and why did I switch?
DOORS is the only system we've used for this purpose. In other cases, we create massive spreadsheets that have links in them and are completely unmanageable, but they do the work.
How was the initial setup?
I wasn't involved in that.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
I would rate IBM Rational DOORS a 10 out of 10. The main reason is that it's what our customers use and what we've been using for many years now, and I don't see any reason to change, frankly.
