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 Vitech Corporation or third party provider that supports the Vitech MBSE methodology. Vitech does offer an MBSE tool set via its 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/).
