We have 10+ years of experience in working model based even before it was
mandatory
(ARP4754B). We started doing it to have consistency and traceablility and to simplify communication. We
developed processes and software tools which make model based systems engineering not only more
fail safe
and
more consistent
than standard document driven development but also
faster
. Now there is no reason to start an engineering project without a central model. Having a single source
of truth in one central model brings consistency, accuracy, efficiency, cost savings, and enhanced
collaboration. The model data is always the reference- that enhances trust, efficiency and effectiveness.
