    Alternatives Considered


    If you have a budget or the need for a complex modeler or need diagram transformation to code or vice-versa, IBM Rational System Architect is the way to go. If you need few diagrams or don't need the complexity or don't have a budget, Bizagi or Star UML get the things done.

    • Reduce costs of recognition of old software.
