AutoFOCUS3 is capable of modeling variability across viewpoints to support product-line engineering and planned reuse. The implemented tooling concept follows a classical 150% approach with feature modeling.
Hereby, the features (or configuration options) which shall be different between the system variants can be modeled in one central feature model.
The optional or alternative model elements in all viewpoints can then be linked to these features via a so called presence conditions.
Finally, system variants can be automatically generated by AutoFOCUS3 after selecting/deselecting features for a variant.
