Modeling Systems in Enterprise Architect

Using SysML in Enterprise Architect, the process of developing a model to design or investigate a system is quick and easy, but at the same time versatile and flexible with a full implementation of the SysML specification. An outline of the stages of the process, and the steps for the initial stage, are provided here.
