What is a Branching Workflow?

Real-world processes rarely follow a single straight path — an expense report under a threshold gets auto-approved, one over it routes to a manager, and one flagged as suspicious routes to fraud review. A branching workflow encodes these conditional paths explicitly, evaluating a rule against the current data and directing execution down the matching branch. The design challenge in branching workflows is keeping the branch logic legible as conditions multiply — a workflow with a dozen nested branches quickly becomes hard to reason about or safely modify. Well-designed systems favor a small number of clear decision points over deeply nested conditionals, and log which branch was taken and why, so a workflow's actual behavior over time can be audited against its intended design.
