Vertical Swimlane Diagram

The Vertical Swimlane Diagram helps teams map any cross-functional process step-by-step, showing exactly which team owns each part of the workflow. Structured as vertical lanes — one per team or role — it uses connected steps and decision diamonds to trace a process from start to finish, illustrated here with a sample request-to-payment flow spanning Customer, Sales, Support, and Finance. Unlike a simple flowchart, the swimlane format makes ownership and handoffs immediately visible, helping teams spot bottlenecks or unclear responsibilities at a glance. Use it to document approval processes, onboarding workflows, support escalation paths, or any process where more than one team is involved and clarity on "who does what" matters.
