IBM Rational System Architect Designer vs. Modelio BA Enterprise Architect

If you need a whole infrastructure and architect view, IBM Rational System Architect is the way to go. If you need a single diagram or your business process is young enough to support hard documenting, you are fine with an open source tool.

Incentivized

• MS Office exporting
• UML modeling
• Transformation to code
• A reverse transformation from code
• Integrates with other IBM products

Incentivized

• Always has a price. And IBM is not cheap
• Sequence diagrams can get messy (still has a good UI)
• Only support few databases as backend repositories like SQL Server and Oracle

Incentivized

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.

Incentivized

• Clients like good modeling. A good diagram reduce costs in incidents and doubts of bad interpretations
• Reduce costs of recognition of old software.
