Complete, feature rich, requirements management software
Commentaires: DOORS, once learned, is a powerful and critical tool for defining requirements, maintaining requirements, as well as tracing to verification and validation. It is an essential tool for engineering development in any regulated industry.
Avantages: DOORS is the most complete and most widely used requirements management software. For medical devices, as well as other highly regulated industries, requirements management is a critical business function. DOORS provides the functionality, traceability, and validity to manage requirements and produce the documentation needed to meet the regulations. DOORS features reduce the risk of missing key requirements, verifications, validations, as well as the flexibility to understand the project as a whole. Managing cross functional reviews of requirements, multiple stakeholders, as well as linked requirements is a huge task that DOORS makes possible with minimal errors. A huge challenge in requirements management is traceability. Tracing requirements to verification, validation, as well as risk analysis, can be very confusing and is prone to errors, but with DOORS these connections can be explicitly defined, and reports or trace documents can be created directly. Also, DOORS scripting allows users to create output documents which can be used as artifacts for the quality system, and shared directly with regulators during audit and for regulatory submissions.
Inconvénients: DOORS has an extensive feature set that covers the whole requirements process. However, these features are not always intuitive to learn. It takes experience to master all of the functionality, and it takes time to become a DOORS master. This is a massive software tool, extensive training or first-hand experience is necessary before it can be used to its full potential.

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.
