Definition
Git is a version control system that allows developers to track changes to code over time, work on the same codebase in parallel, and merge their changes together safely.
Importance
Without version control, tracking who changed what, recovering a previous working version after a bad change, or having multiple developers work on the same codebase without overwriting each other's work becomes genuinely difficult. Git has become the near-universal standard for this, which matters practically: it means new developers joining a project can work with familiar tools rather than learning something bespoke.
Application
We use Git as standard practice across all development work, structuring branching strategies and review processes so changes are tracked, reviewed, and reversible at every stage. This underpins CI/CD pipelines directly, since automated testing and deployment triggers depend on a clean, well-managed Git history, and it gives clients full visibility into what changed, when, and why, across the lifetime of a project rather than just at delivery.
