## Summary

When every team can ask ChatGPT or Copilot, ungoverned answers multiply. Enterprise architecture must own curated, metamodel-aware context so agents and humans decide from the same living map — with evidence.

## What changes when everyone can ask an AI?

Questions no longer wait only for key people — they go to bots. Divergent document piles → divergent confident answers.

## Why can’t every team just use Copilot on their docs?

RAG retrieves passages; it does not maintain a curated metamodel or resolve conflicts. Plain Copilot/RAG is not enough for trustworthy EA answers.

## What does “EA owns enterprise context” mean?

EA governs the living map of entities, relationships, and evidence for humans and agents — with curation and citations.

## Pro-AI, pro-trust

Agents become useful when grounded in owned context (Enterprise Ask on a living map).

## What if EA does not own it?

Competing bot authorities, unauditable recommendations, delivery outrunning memory.

## How does DecisionPen solve this?

Owned curated metamodel map as shared authority; Enterprise Ask with evidence citations; not plain RAG over Confluence; same context for strategy, SAs, and generated artefacts so every squad bot is not a competing architecture office. Trial: https://decisionpen.com/trial

## When is DecisionPen not the right tool?

Primary diagramming canvas (Visio, Lucid, BPMN).

Governed living map + evidence for decisions.
