With the takeover of Geensoft Dassault today offers also the Reqtify request management. Using Reqtify requirements for a product can be allocated and managed centrally. Via over than 60 interfaces to other sources such as Word, Excel, PDF, DoorsTM... requirements can be very easily taken as texts or data. Via hierarchical structures a specification can be derived from the text which again is linked via interfaces to the design and development data.

Dassault Reqtify

These structure enables via a relation matrix to display the requirements with the respective development blocks. This diagram si not only necessary for documentation as it is required in some standards (ISO, FDA, CMMI oder FAA). Rather it can be controlled which development blocks cover which part of the requirement list. So design blocks can be recognized, that if so have become needless with changing specification. Furthermore also all affected blocks can be clearly recognized with changing parameters and so the time involved for modifications can be evaluated. Requirement Traceability and Impact Analysis are the generic terms that describe all mentioned functions.

Standards that are demanding a Requirement Traceability are:

  • Aerospace DO178B DO178C, DO254, ARP…
  • Automotive: ISO 26262, IEC 61508
  • Medical technology: IEC 62304, QSR 21CFR part 820.30, FDA 21 CFR
  • Railway technology: EN5012x

The requirements can be
referenced directly with the development data. Via the over than 60 interfaces to applications (c++, java, xml, mCAD, eCAD,...) the individual design steps are assigned to the requirements. This assignment can be displayed in both directions: Which requirement is fullfilled by which design blocks and which design block is involved in the implementation of which requirements.

The tool has also the possibility du show clearly the project progress. So the level of completion (requirement coverage) can be displayed for the whole project or also for hierarchical blocks. That way prolongations of the project term can be identified early and appropriate action can be taken.
