• 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

• There is no process framework tool offered by Vitech Corporation or third party provider that supports the Vitech MBSE methodology. Vitech does offer an MBSE tool set via its CORE® product suite.

• 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/).
