### Git Branch-based Code Promotion Strategy

Source: https://growth.rcpch.ac.uk/safety/csmf/clinical-risk-mgmt-plan

Describes the standard 'code promotion' process using a Git Branch-based strategy for deploying changes. New features are developed in separate branches, reviewed, and merged through stages like 'test' before reaching the 'live' branch.

```text
New features are developed in branches specific to that feature. Following successful testing, user acceptance, and automated tests, a successful feature can be merged into the next branch 'up' which may be a `test` branch or other nomenclature. The process of merging requires code review by nominated individuals and is a further opportunity for clinical safety review.
Code in the `live` branch is changed relatively infrequently (except for urgent security or safety updates) but the code which is promoted into `live` would have by then undergone several rounds of review as it progressed through our branch promotion strategy.
```
