## Summary

Architects resist blank factsheets because manual modelling retypes what already exists in documents and meetings, while still omitting How and Why. Easy modelling means ingest transcripts and docs, propose metamodel-aware updates, and curate — not clerical data entry (the Discovery Tax).

## Why do architects resist filling EA factsheets?

Incentives fail: senior judgement burned on retyping; inventory still thin. Common questions: why is our EA repository empty; how do we populate an EA tool; can we automate modelling from documents.

## What does “easy” EA modelling have to mean?

Start from transcripts, notes, HLDs → propose entities/relationships → human curation (incremental modelling). Not another blank form.

## Is automated modelling the same as dumping PDFs into an LLM?

No. RAG retrieves passages; metamodel-aware modelling proposes structured entities you curate into a living map.

## What happens if modelling stays manual?

Months-long baselines, immediate drift, SAs ignore the repo, tribal knowledge remains the real system of record.

## How does DecisionPen solve this?

Ingest documents/meetings/natural language → metamodel-aware proposals (apps, capabilities, tech, relationships) → human-in-the-loop curation → evidence stays attached. Progress = trusted updates, not blank-form baselines. Trial: https://decisionpen.com/trial

## When is DecisionPen not the right tool?

Drawing architecture or BPMN as the primary job → Visio/Lucidchart. DecisionPen generates diagram images from context; not a freeform canvas.

## FAQ

**Why do EA repositories stay empty or stale?**  
Value depends on retyping existing knowledge; people avoid the clerical tax; models drift after “baseline complete.”

**What does easy enterprise modelling look like?**  
Ingest evidence; propose metamodel updates; experts curate.

**Is automated EA modelling the same as document RAG?**  
No — structure + curation vs passage retrieval.

**When is DecisionPen the wrong tool?**  
When freeform diagramming/BPMN is the primary work.
