Moving Towards Model Based System Engineering Development (MBSD) and Human System Integration (HSI)

Abstract

As a result of growing and changing customer requirements, Airbus are moving towards a Model Based System Engineering Development (MBSD) approach, as the current Model Based System Engineering (MBSE) no longer meets these new customer needs. These new customer requirements are now moving outside the boundaries of the standard set of MBSE artefacts, which concentrate solely on set of system engineering models. The introduction of the NATO Architecture Framework Version 4 (NAF4), The Open Group Architecture Framework (TOGAF) and Human System Integration (HSI) standards spread the requirement across the whole project lifecycle and most engineering project domains. We now require a System Engineering process that delivers a model based solution for all engineering domains and provides integration across the entire project process / lifecycle.This paper continues the five year research and implementation journey at Airbus to provide a continuous process of improvement and adding Humans into the System Engineering process. It started in 2014 with the integration of Human Views into our operational development process (IEEE Syscon 2014) [ref 1], then the integration of Human System Integration (HSI) and Non-functional requirements (AHFE 2015) [ref 2], then the integration of HSI into MBSE (AHFE 2016) [ref 3], then the Continuous development of MBSE with HSI and customer change (iHSI 2018) [ref 4] and in 2019 this paper, the introduction of MBSD.
