This webcast presents the IBM® Rational® HarmonyT for Systems Engineering process for the model-based systems development. Based on a small set of key principles and practices from the IBM® Rational® HarmonyT library of best practices, the Harmony for Systems Engineering process provides step-by-step guidance on who does what, and when they have to do it. Harmony for Systems Engineering is a model-based development process built upon the UML and SysML languages. These standard-compliant languages allow Harmony for Systems Engineering to seamlessly integrate systems engineering and software development. Harmony for Systems Engineering incorporates overall project flow with efficient design iterations to improve stakeholder requirements definition, requirements analysis, design synthesis, interface definition and early validation via executable models.
