On Tuesday, March 1st 2011, The NASA Goddard Space Flight Center held their monthly Systems Engineering Seminar. The speaker was INCOSE Chesapeake Chapter’s very own President-Elect and Senior Principal Enterprise Architect at Northrop Grumman, Gundars Osvalds. President-Elect Osvalds gave his lecture on Model Based Systems Engineering (MBSE) to a robust audience of nearly 60 people.

Mr. Osvalds started by noting the advantages of using MBSE. It provides an efficient methodology to capture, allocate, trace and verify requirements. He furthered that the use of integrated diagramming helped to provide a cohesive view of the architecture, as well as test plans and flows into and out of interfaces and specifications. He described SysML as an extension to UML to provide a modeling capability for the Systems Engineers to create static and dynamic models of the systems architecture.

Another defining characteristic of SysML is that it can be grouped into four functional areas; Requirements, Structure, Behavior, and Parametrics. Gundars went on to talk about Black Box: Conceptual Model and the White Box: Logical and Visualization (a Northrop Grumman concept) Models. Using these models the SysML can also provide requirements traceability and Use Cases in order to provide context to the system being designed. At the end he showed a visualization video of the program he was working. Following the video he fielded a handful of questions. To close out the seminar, Mr. Edward Amatucci presented Gundars with a Certificate of Appreciation for taking the time to share his knowledge of Model Based Systems Engineering with the NASA Goddard Space Flight Center audience.
