The standard for systems engineering artifact creation - but not the easiest to use.
Commentaires: The ability to use DOORS databases from existing projects, and incorporate model-based systems engineering workflow using MagicDraw is tremendously valuable, but if DOORS isn't a central requirement, I do prefer the Vitech CORE and Genesys offerings for fixed scale applications, and vastly prefer Innoslate for Enterprise and Cloud solutions where concurrent engineering is valuable.
Avantages: The ubiquitous capability within the DOORS toolset is undeniable, and the interface with MagicDraw enables useful systems engineering artifacts to be created with ease. The integrated nature of the entire Rational suite is actually very robust, and if working with a legacy project where DOORS is implemented, MagicDraw can be tremendously helpful in converting larger spreadsheet flavored artifacts into something actually parse-able to most human brains.
Ease of use is the biggest limitation, particularly with doors. An indirect side benefit of having a large database in DOORS is that configuration management occurs indirectly because only a small number of people can properly execute a change, therefore version control happens because only one (or maybe two) person is actually inputting the information.
The flexibility in MagicDraw is somewhat limited, even with some creative metamodel application. Not a massive drawback or worth looking elsewhere as a singular cause, but it is a capability limitation in some instances.
Value is the other serious drawback - to implement the full Rational suite is actually a solid chunk of change, and to really get full utility out of the entire IBM Rational package, at least two applications are requisite (unless you are a DOORS specialist, in which case my express condolences go out to you). The value proposition of Vitech offerings, and for anybody looking to use OML the much better value of Innoslate really are the reason I use the IBM Rational toolkit sparingly, and only when somebody else is footing the bill.

Rational Tool Concert (RTC)
Commentaires: RTC is a highly configurable enterprise wide large scale tool for supporting initial engagement of ideas that can be distilled down into epics, features, stories and tasks.. Configure the level of granularity and what you want to capture at each level with highly customised forms to capture requirements and track through to build. Not so suitable for developers who find the burden of forms and multiple screens for data capture annoying. RTC is great through initiation, planning, and testing. Also great for real time report dashboards and has preloaded a number of report types, charts, pie, bar etc for building informative dashboards. Take care to establish initial configuration approach and data structure before creating forms and onboarding people as it is hard to correct sttucture changes. It does require a dedicated config person initially and support staff. Deployed in IBM, Telstra, NBN to give you an idea of scale
Avantages: Highly configurable. Strong work flow. Real time dashboard. Audit history. Can attach files. Good security profile management. Scaleable, flexible, powerful
Inconvénients: Requires config, training and support staff. Licenses are expensive
