==== Vitech Model-Based Systems Engineering (MBSE) Methodology ====

=== Overview ===

  * Four (4) primary concurrent SE activities linked and maintained through common system design repository

  * Each activity linked within context of associated “domains”
    * Process Domain (SE activities)
    * Source Requirements Domain
    * Behavior Domain
    * V&V Domain
    * Architecture Domain

  * Strong adherence to agreed upon System Definition Language (SDL), i.e., SE schema or ontology to manage syntax and semantics of model artifacts

  * Uses incremental process known as “Onion Model”
    * Allows complete interim solutions at increasing levels of detail during system specification process
    * Lower risk design approach by checking for completeness and discovering constraints early in design process

  * Detailed testing methods described in support of system V&V activity

=== Tool Support ===

  * There is no process framework tool offered by [[http://www.vitechcorp.com/|Vitech Corporation]] or third party provider that supports the Vitech MBSE methodology. Vitech does offer an MBSE tool set via its [[http://www.vitechcorp.com/products/index.html|CORE®]] product suite.

=== Offering/Availability ===

  * In the past, a half-day tutorial on the Vitech MBSE methodology was offered at various INCOSE International Workshops and Symposia. This tutorial was entitled “H0D: Model Based Systems Engineering for Project Success: The Complete Process (PM)” and was taught by James (“Jim”) E. Long as well As David A. Long, President of Vitech Corp. More detailed, multi-day courses are offered through the Vitech training services (see http://vitechcorp.com/services/).
