# Greenfield Development

> An abstraction of building a new system with no inherited code, so its boundaries are designed from the current forces.

Record: `architecture:greenfield-development`
Kind: model

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Minimum Viable Architecture](https://banes-lab.com/records/architecture/minimum-viable-architecture.md) and before [First-Principles Design](https://banes-lab.com/records/architecture/first-principles-design.md).

## Repair

- Refactored by: Start Modular, Add ADRs, Define Boundaries
- Detected by: heavy structure without validated need
- Violated by: premature irreversible architecture choices
- Measured by: [initial complexity](https://banes-lab.com/records/lexicon/initial-complexity.md), adaptability
- Enforced by: [architecture review](https://banes-lab.com/records/architecture/architecture-review.md)

## Requires

- [First-Principles Design](https://banes-lab.com/records/architecture/first-principles-design.md)

## Reinforces

- [Architecture Foundation](https://banes-lab.com/records/lexicon/architecture-foundation.md)

## Enables

- [Clean Boundary Design](https://banes-lab.com/records/lexicon/clean-boundary-design.md)
