In Part 1 of this series, we connected individual requirements in DOORS NG to requirements and other elements in SysML. Greater challenges arise when we need to map requirement structure and organization between tools, because different tools organize requirements in significantly different ways. SysML tends to organize requirements in simple tree hierarchies using containment relationships.

Introduction Every system development project has both product-specific and project-specific considerations: Product-specific includes product requirements (market, technical, regulatory), product function and hardware and software design Project-specific includes organization structure, project requirements, and product development methodology The intersection of these two domains is often the Work Breakdown Structure (WBS) which captures the product-specific tasks in the

Of all the use cases potentially supported by Syndeia, links between systems engineering and project management are among the most intriguing. With Syndeia 3.0, a new interface to JIRA’s issue tracking repository offers a window into some of these possibilities. JIRA, widely used in agile software development, is organized by project and issue. As well as

As a project moves from architecture definition to component design, new software tools, such as mechanical computer-aided design (MCAD), become part of the engineering process. The impact of component design decisions needs to be continuously evaluated at the system level. The Syndeia interface for PTC Creo supports a number of use cases from either MagicDraw

In Part 1 of this series, we explored how Syndeia 3.0 generates global displays of connections between various engineering software tools. While these global displays (e.g. Figure 1) provide a snapshot of graph complexity, some very important use cases require us to trace out chains of individual connections and identify those model elements that may

The Object Management Group (OMG) held its Technical Meeting in Chicago last week, Sep 12-16, 2016. We had the opportunity to present Syndeia at the Systems Engineering Domain Special Interest Group (SE DSIG) meeting on Sep 13. In the presentation, we dived into the motivation and the technical philosophy behind Syndeia – to build a Total System Model that

The Internet of Things (IoT) holds enormous promise of new capabilities for users and new opportunities for businesses. It also presents enormous challenges to systems engineers. Model-Based Systems Engineering (MBSE) potentially provides an efficient way to address those challenges, being holistic, integrated, flexible and object-oriented. To explore this promise, Intercax has started a series of

The Martian by Andrew Weir (2014) is a great read and now a hit movie. The astronaut hero and the expert SysML modeler have several things in common. First, they have the ability to take a complex system and adapt and reuse its components to new purposes. Second, both do careful calculations of system performance

Advanced Model-Based System Engineering MBSE organizations are moving beyond the use of modeling to make “pretty pictures”. SysML parametrics are a way to add spreadsheet-like calculations to descriptive architectural diagrams. And roll-up calculations are among the most common use cases in systems engineering. Starting with a multi-level bill-of-materials or master equipment list, we want to calculate
