Available Courses

For teams that wish to learn about model-based systems engineering – whether simply to appreciate the fundamental concepts and applicability or to transform their practice – our supporting team of seasoned practitioners at Vitech Corporation delivers a variety of sessions ranging from two hours to two days designed to suit your team’s needs. The objective of these sessions in model-based systems engineering is to provide your team with a basic familiarity with the concepts of model-based systems engineering as practiced in Vitech Corporation’s layered approach known as the STRATA™ method.

These sessions can be presented in a variety of formats, tailored to the needs of the audience. The training design allows it to target both technical and non-technical audiences. In either case, the basic concepts of model-based systems engineering are presented using language and examples appropriate to the audience. The content is also designed so that it can be delivered in varying levels of detail. This allows the training to be tailored to a two day, one day, half day, or two hour format. (One hour and keynote presentations are also available, though these thought-provoking sessions are certainly of a different scope than the training courses). Vitech will work with you to identify the appropriate delivery and timeframe for the course.

Participants completing these sessions will emerge with a basic understanding of the concepts of model-based systems engineering and the value adding advantages of the model-based approach. Whether a program or project manager or a hands-on systems engineer, he or she will have an understanding of how and why the model-based approach differs from other, more traditional methodologies.

These sessions are designed to serve the needs of a variety of role players on your team. Vitech will use its ability to tailor this offering to your exact audience in order to emphasize those subjects and perspectives that best meet their needs.

  • Program or project managers who desire to achieve a basic understanding of the nature and advantages of model-based systems engineering will understand the MBSE principles in the context of their responsibilities.
  • Acquisition professionals seeking an understanding of model-based systems engineering methodologies and the potential value add to acquisitions programs and projects they procure will see how MBSE can leverage their understanding of the problem driving their acquisition and result in proposals that address program needs.
  • Systems engineers familiar with the concepts of traditional systems engineering but new to the model-based systems engineering methodology will build on their existing knowledge and experience to see how to use MBSE as a “force multiplier” for their engineering efforts.
  • Agile developers seeking to bring a systems perspective to their agile development work will learn how MBSE can feed their backlog and tie their work to the system design effort while enhancing the agility they value.

The training begins by exploring the traditional approaches to systems engineering focusing on document-centric waterfall approaches. The problems with these approaches are discussed in ways which provide a contrast to model-based systems engineering. In particular the issues of stove piping, limitation to clean sheet or top-down design, and complexity management are explored.

This is followed by an explanation of the model-based approach. The course sets out the characteristics of the model and how it can be used to obtain an efficient and effective system design. Beginning with the definition of the system boundary, the training explains the major tasks of model-based system design. As these tasks are discussed the system design issues facing the engineering team are described. The handling of these issues in the model-based systems engineering methodology is contrasted with their treatment in the more traditional approaches.

In addition, depending upon the time available and the needs of the audience, specific issues and opportunities can be discussed. The course can be constructed to include modules discussing leveraging service-oriented architectures, working within the DoDAF environment, dealing with model-based systems engineering in an agile development setting and other timely issues.
