This has a number of negative effects on productivity, including:

- Unclear ownership of code.
- Difficult to focus on one particular area.
- Unintended coupling between areas of the code, including tests.

## Decision

Organize the Gradle code base into a set of coarse-grained "architecture modules".
An architecture module is responsible for providing a coherent set of features and:

    features {
        publishBuildStatusToGithub(model)
    }
