## Summary

Annual capability posters go stale quickly. Capability maps stay useful when they evolve from living application, process, and evidence facts — hybrid top-down frame + bottom-up reality — with human curation.

## Why do capability maps go stale?

Workshop → poster/PDF → disconnected from changing systems and evidence.

## Should capabilities drive applications or the reverse?

Both. Capabilities frame strategy; living application/delivery facts refine the frame.

## How do living facts update a capability map?

1. Incremental capture of apps/processes/evidence.  
2. Propose capability links and maturity shifts.  
3. Architect curation.  
4. Roadmaps, Ask, and generated docs consume the updated map.

## Poster vs living model

A poster communicates. A living capability map is decision infrastructure when How/Why evidence stays attached.

## How does DecisionPen solve this?

Capabilities as first-class metamodel entities linked to apps/evidence; incremental modelling proposes updates; architects curate; Ask and generated docs consume the current map instead of last year’s poster. Trial: https://decisionpen.com/trial

## When is DecisionPen not the right tool?

One-off Visio capability poster with no living link to systems.

## FAQ

**Why do capability maps go stale?**  
Published once; never reconnected to changing facts.

**Should capabilities drive applications or the reverse?**  
Both directions in a hybrid loop.

**How do living facts update a capability map?**  
Incremental proposals + curation → consumed by roadmaps and Ask.

**When is DecisionPen the wrong tool?**  
Static diagram-only capability posters.
