IBM Rational DOORS Next Generation is the master for capturing requirements. The solution does have other use cases, however, most of our customers are using DOORS as a requirement capturing software. High-level requirements or stakeholder requirements are captured mainly in DOORS.
There are many good features with DOORS. The solution has a concept of streams and baselines, as well as a concept of components. A component is a subproject inside a project.
IBM Rational DOORS Next Generation has the capability to extend or add extensions to the data model.
Another valuable feature would be the ease to add custom attributes and new objects with DOORS.
The user interface of IBM Rational DOORS Next Generation needs to be improved, there is a lot of scope with this. Even though there have been improvements from versions five, six and seven, the UI still has a lot of bugs.
There is room for improvement in the APIs that they have exposed for integration. The solution relies on OSLC for integration APIs, but those APIs do not support all the capabilities.
I have been working with IBM Rational DOORS Next Generation for five years.
The solution is not very stable. The performance could improve. We generate a lot of data, causing DOORS to become sluggish with some lags in the software. The earlier version of DOORS Classic handled a large amount of data better.
IBM Rational DOORS Next Generation can scale up and down, but there is a lot of scope for improvement required in this regard.
Personally, I have not interacted with IBM Rational DOORS' customer service and support. We have our own support team.
The initial setup is medium in complexity. It is not straightforward. The admin console itself is a little tricky to understand within the whole licensing model and user access control.
I would rate the initial setup a four point five out of five.
From what I know of Jama Connect, Micro Focus, and Inflectra, DOORS Next Generation is the number one requirement management software. There are other product options, but I believe that DOORS is the best offer out there.
Overall, I would rate IBM Rational DOORS Next Generation an eight out of 10.
