A workflow is a sequence of activities, decisions, handoffs, and system actions used to move work from an initial trigger to a completed outcome.
Consider an expense approval process. One employee submits an expense, a manager reviews it, finance checks policy, the system may flag exceptions, and the final result is reimbursed or rejected.
That is not one user flow. It is a workflow connecting several people and states.
A task flow follows one user completing one task. A workflow can combine many tasks across people and systems.
A user flow stays close to a person’s interaction with the product. A workflow can include invisible system actions, organizational steps, and other participants.
Many workflow problems happen between people and systems rather than inside one screen.
A state without a clear owner often becomes a queue nobody manages.
Real workflows break at permissions, missing data, delays, and approvals.
A workflow answers: how does this piece of work move across people, systems, decisions, and states until it is done?
