Broadening Access to the MBSE System of Record

While Systems Engineers create models during the design, simulation and trade-off analysis of complex systems, the information contained in these models is useful across the entire organization.  Business stakeholders may want to check their requirements will be implemented in the system. At the same time, domain-specific engineers may need to see the system architecture to determine the functions they need to implement in software, electronics or physical parts.  Quality and certification staff may need to prove traceability or assess the impact of possible changes. Systems models contain useful information that a wide range of job roles can benefit from, so how can organizations provide broad but controlled access to their Integrity Modeler Model Based System Engineering (MBSE) system of record?

Enable universal access

In the past, if Integrity Modeler users wanted to share model data with other stakeholders, they could only run a report showing a point-in-time snapshot of the model. While anyone with access to Integrity Modeler’s rich Windows client could access all model details, infrequent users often don’t want to install a client on their desktop. The good news is that along with the traditional graphical user interface, Integrity Modeler provides a Web interface that displays in a Web browser.

The web interface provides live access to the most up-to-date model and information. By simply refreshing the web page, users see the latest model changes. This means a business stakeholder or other interested party could be discussing the model remotely with the engineer updating the model in real time, seeing the same views as the engineer.

Take advantage of rich functionality

When users access the model via the Web interface, they can access all the same model diagrams and data that are available via the Windows client. Packages are shown in a hierarchy format similar to Windows folders. Through the Web interface, users can access a carousel (not available in the Windows client) to browse through diagrams and model contents.

 Users can also:

  • Access rich filtering and search options

  • Zoom in and out on diagrams
  • View tables and matrices that show mappings and even view text “diagrams” (i.e., documents)

  • View decision sets
  • View and navigate item relationships, including relationships with requirements

  • See all options selected in a variation models
  • See and navigate everything in the model to understand the model, give feedback, and more
The Web interface references every model item and diagram with a URL, making it easy to share links to diagrams and model items via email or to embed links in any document. It applies the same authentication delivered in the standard Integrity Modeler Windows client, enabling full security for access control.
