What is a process flow diagram?

A process flow diagram (PFD) is a visual representation of the steps, decisions, and connections in a process, from a starting point to an end result. It uses standard symbols, rectangles for process steps, diamonds for decision points, and arrows for flow direction, to make the sequence of activities clear to anyone reading it. Process flow diagrams are used in manufacturing, business operations, software development, chemical engineering, and supply chain management to document procedures, spot bottlenecks, and communicate how work gets done. Figviz generates a labeled PFD from a plain description of your process, so you can visualize any workflow without drawing shapes by hand.

Keep each box to one action or decision, and use consistent verb-noun phrasing such as "Review Invoice" rather than "Invoice is reviewed." Place decision diamonds so the default or most-common path flows straight down and the exception branches to the side, which keeps the diagram easy to scan. For engineering PFDs, label every stream with a flow direction arrow and identify each piece of equipment so operators can trace the path without guessing. Use the colorful style to distinguish departments or process phases at a glance, and export at 4K for crisp print quality in standard operating procedure documents.

Process flow diagram vs flowchart

The terms are often used interchangeably, but in engineering a process flow diagram (PFD) refers specifically to a diagram that shows the equipment, stream connections, and operating conditions of an industrial process, without the detail of a piping and instrumentation diagram (P&ID). In business and IT contexts, a process flow diagram and a flowchart mean the same thing: a step-by-step visual of how work moves through a system. Figviz handles both uses, generating business-process flowcharts and engineering-style PFDs from a description of what you need.
