Process Flow is a business analysis model that visually represents the steps taken in a process by a human user interacting with a system implementation. It illustrates the sequence, decision points, and handoffs involved in completing a task or delivering an outcome.
A similar structure, called a system flow, is used to show steps executed automatically by a system without human intervention.
Key Characteristics
- Step-Based Visualization – Shows actions, decisions, and flow of control
- Human Interaction Focus – Emphasizes user-system interaction
- Sequential Logic – Follows the actual order of operations
- Supports Documentation and Analysis – Useful for identifying inefficiencies or improvement areas
Example Scenarios
- A user submits a service request, which is reviewed, assigned, and resolved through a tracked flow
- A purchase approval process moves through user submission, manager approval, and finance verification
- A support ticket process includes triage, assignment, escalation, and resolution steps
Example Process Flow

Why Process Flow Matters
- Clarifies Work Execution – Helps teams understand how tasks are completed
- Enables Process Improvement – Identifies redundancies, delays, and decision points
- Supports System Design – Informs system requirements and automation potential
- Improves Stakeholder Communication – Provides a shared visual language for understanding workflows
