An MBSE Framework to Support Agile Functional Definition of an Avionics System.

In avionics domain, there have been many efforts in recent years to build a MBSE methodology with tooling support. The main purpose is often to improve quality and efficiency of system definition, architecture and integration. Sometimes there is also an additional objective to ease system verification and validation. This paper introduces an additional challenge with the support of an agile development cycle to ease impact analysis and incorporation of late and changing requirements at different times. It presents key principles and requirements of an agile MBSE approach and presents associated modeling activities with illustration on an avionics case study.
