## Summary

DecisionPen covers core EA modelling (landscape, capabilities, applications, roadmaps/reporting) with LeanIX metamodel support, and goes further with unstructured evidence, natural-language modelling, and incremental updates. It can complement LeanIX or support a switch via metamodel compatibility.

## Key differences

| Theme | Traditional EA | DecisionPen |
|-------|----------------|-------------|
| Inventory | Strong | Strong |
| How/Why evidence | Often external | First-class with entities |
| Population | Manual factsheets | Incremental + NL modelling |
| Ask | Limited | Map-grounded with citations |
| SA artefacts | Parallel docs | Templates from living context |

## Product boundary

Not a freeform diagramming or BPMN canvas (Visio/Lucid). Generates diagram images from curated context.
