DOORS facilitates the adoption of a chain toward DevOps architectures. Using all the IBM Rational tools, we can trace all activities related to a project, from beginning to design to development.
For example, we use Rational Rhapsody to design models, incorporate requirements, and then generate software from those models. We also use Rational Team Concert to plan tests and Jenkins for continuous delivery.
The biggest improvement for me is definitely the ability to use DOORS in a web environment through Rational DOORS Next Generation. Integrating with Rational Team Concert via the web interface has also been beneficial.
However, not all Rational Team Concert operations are available from the web client. Certain operations, like creating streams or components, still require using the desktop application. They're not accessible through the web interface.
And in my opinion, this limitation should be removed.
Creating streams, components, etc. We still need the desktop app for those.
DOORS has enabled flexibility in mapping requirements to the software. Tracking changes over time due to team meetings and other factors is important.
Additionally, I've been using DOORS Next Generation, the web-based tool, especially in the last year.
