Git Branching Strategy,
as a requirement diagram.

A Git Branching Strategy Requirement Diagram captures the formal rules, constraints, and dependencies that govern how code moves through a repository. Whether your team follows trunk-based development—where all developers commit frequently to a single main branch—or GitFlow, with its structured release, feature, and hotfix branches, this diagram type translates those policies into traceable, verifiable requirements. Each node represents a specific rule (e.g., "feature branches must be merged within 48 hours" or "release branches require two approvals"), and relationships between nodes show dependencies, conflicts, and priorities. The result is a living specification that bridges the gap between informal team conventions and enforceable engineering standards.

## When to Use This Template

This template is most valuable during onboarding, toolchain migrations, or compliance audits. When a team is adopting GitFlow for the first time, a requirement diagram makes implicit branching rules explicit, reducing merge conflicts and broken pipelines. For trunk-based development, it helps enforce the short-lived branch constraint and continuous integration gates that the strategy depends on. Platform engineers, DevOps architects, and engineering managers will find it especially useful when documenting branching policies for regulated industries, multi-team monorepos, or open-source contribution guidelines where clarity is non-negotiable.

## Common Mistakes to Avoid

One frequent error is conflating process steps with requirements. A requirement diagram should state *what must be true*, not *how to do it*—so "all commits to main must pass CI" is a valid requirement node, while "run `git merge --no-ff`" is a procedural instruction that belongs in a runbook. Another mistake is over-specifying: teams that document every minor convention end up with diagrams too complex to maintain. Focus on constraints that, if violated, would cause integration failures, security gaps, or release delays. Finally, avoid treating the diagram as static. Branching strategies evolve as teams scale, and requirement diagrams should be versioned alongside your repository configuration to stay accurate and actionable.
