‘Requirements management’ is the process of capturing, organising,
tracing and managing project requirements and measuring the impact of
change throughout a project's lifecycle. DOORS (Dynamic Object-Oriented
Requirements System) is one such system from Quality Systems & Software
(QSS); it enables users to include a vast number of requirements in their
product design, production and delivery to ensure full compliance with
specified standards. MathWorks subsidiary, Cambridge Control has now
developed an interface that integrates this package with its Matlab,
Simulink and Stateflow technical computing software, allowing DOORS and
MathWorks products to manage requirements throughout the development
lifecycle of mid to large-scale technical projects.
The graphical user interface, or 'Navigator' allows users to move easily
between DOORS documents and Matlab M-files, Simulink models and Stateflow
diagrams. Users can modify and delete requirements quickly and easily and
analyse the impact changes will have on models and prototypes.
