DOORS ( D se Dynamic O bject O riented R equirements S ystem ) is a requirements management software , which was developed by Quality Systems & Software (QSS) in the early 1990s. The first version of DOORS was used by the United Kingdom Department of Defense in February 1991. The first commercial version of DOORS was published in April 1993 at the Software Technology Conference in Salt Lake City. QSS was purchased by Telelogic on August 8, 2000. The acquisition of Telelogic was in turn completed by IBM on April 3, 2008.

In the document style, DOORS enables a structured recording and management of requirements (objects) that can be assigned attributes that the user has selected. In order to be able to differentiate between the requirements, DOORS provides each object with a unique identification number. A table view of the objects also shows the requirements and the associated attributes. Doors can import and export (also formatted) texts and images from Microsoft Word and Excel. The formats stored internally as RTF (including OLE objects) can be viewed, but (e.g. text colors) cannot always be edited. The user interface of Doors cannot be operated without a mouse, as some commands are only available as symbols and not via a menu. Entering text is a bit more cumbersome than z. B. in Word, since its classification (object on the same or subordinate level, heading or content) must be selected before each paragraph.

For the tracking requirements during the project (tracing) objects can be linked. The traceability links can be created between two requirements via the menu or by drag-and-drop. In addition to the request, DOORS shows a link indicator after the link, which uses the arrow direction and color to show an outgoing or incoming link. At the same time, the link indicator can be used to navigate between the linked requirements.

All changes to objects are saved in a history, whereby differences in OLE objects can be logged, but not always viewed. The status of a module can be stored reproducibly in a baseline , several modules can be organized in baseline sets, and baselines can be compared with one another.

DOORS is a client-server application and is based on a proprietary database . Various analysis tools are available. The automation of operating processes is possible with the script language DXL (DOORS eXtension Language).

The data can be used from DOORS to create a UML 2.0 model. DOORS supports the Requirements Interchange Format (RIF / ReqIF) for data exchange and Open Services for Lifecycle Collaboration (OSLC) as an interface to test management, change management and modeling tools.

DOORS is used in areas such as space travel , aviation , the automotive industry and rail technology for system and software specification in requirements management .

Laplante introduces DOORS as one of five commercial tools for requirements management. The software is also given further consideration by Ebert.
