Two widely used modeling languages are Unified Modeling Language (UML®) and Systems Modeling Language (SysML). Here at ArgonDigital we use our Requirements Modeling Language (RML®) to create and define software requirements visual models. RML® approaches software from the business analysis or product management perspective and focuses on specifying needs, rather than the solution designs like UML and SysML do. Instead of focusing intensely on complex system design models, RML® looks at a project’s goals and objectives. RML® then uses models to break down these objectives into requirements which are easily understood by both business stakeholders and developers. By focusing on objectives instead of system design, RML® forces teams to hone in on designing systems which maximize value to a project.
UML and SysML are very useful modeling languages for designing and developing systems of course. The RML® models actually can be used as a starting point for many of the models within UML and SysML.
See the adjacent chart for a full comparison of RML, UML and SysML.
The .zip file contains the full suite of RML® visual models and templates – 22 different business analyst templates! – in various formats (Microsoft Word, Visio, and Excel), all of which are outlined and explained in the book Visual Models for Software Requirements.
We can help you and your teams define clear outcomes in order to prioritize the initiatives that will drive the most value for your organization.
