Voice from Chairman of OMG, Inc.

"SysML is already the industry standard for engineering large, complex systems;"
more safety and quality system development teams are rapidly adopting the language every day. Now every engineering specialty,
from mechanical, to electronic to software engineering have a common language to design safe, complex systems architectures.
We are pleased to welcome Astah to the fold, a unique modeling tool from Japan, from leading OMG member Change Vision."
