|
|
`/arckit:application-rationalization` turns the application inventory into portfolio decisions. It applies keep, merge, replace, and retire recommendations with rationale, target-state implications, benefits, risks, and implementation sequencing.

## Inputs
|
|
|
|
| Artefact | Purpose |
|
|
|----------|---------|
|
|
| Application inventory (`ARC-<id>-APP-v1.0.md`) | Mandatory application baseline |
|
|
| Business capability map (`ARC-<id>-BPCM-v1.0.md`) | Capability criticality and target capability support |
|
|
| Architecture decision records (`ARC-<id>-ADR-*.md`) | Existing platform and technology decisions |
|
|
| ADM preliminary (`ARC-<id>-ADMP-v1.0.md`) | Transformation scope and strategy context |
|
|
| Transition architecture (`ARC-<id>-TRANS-v1.0.md`) | Existing migration sequencing if already planned |
|
|
| Vendor contracts or cost models | Licensing, support, commercial constraints |
|

## Decision Model
|
|
|
|
| Decision | Use When |
|
|
|----------|----------|
|
|
| Keep | Application is strategically aligned, healthy, and cost-effective |
|
|
| Merge | Duplicate capabilities can be consolidated into fewer services |
|
|
| Replace | Capability is needed but the current application is unfit |
|
|
| Retire | Capability is obsolete, unused, or better served elsewhere |
|

## Review Checklist
|
|
|
|
- Every decision is evidence-backed, not preference-based.
|
|
- Critical capabilities remain covered in the target state.
|
|
- Retirement and replacement decisions include migration and data handling notes.
|
|
- Vendor, licence, and contract constraints are visible.
|
|
- Pending approvals are explicit and traceable.
