PROGRAM FLOWCHART (Focus: Code & Logic), Maps the step‑by‑step algorithm a computer follows inside a single program., Uses decisions (diamonds) and loops to show exactly how the code executes., Designed for programmers to debug or plan a specific function like a login script., Shows variable assignments, arithmetic operations, and conditional branching., Lives entirely inside the software world—no hardware or paperwork included., PROCESS FLOWCHART (Focus: Workflow & Operations), Illustrates the sequential steps of a non‑tech task, like assembling a burger or processing an order., Shows who does what, when, and where handoffs happen between people or departments., Often includes waiting times, inspections, and movement of physical items., Used by business managers or factory supervisors to improve efficiency., Does not show computer code—instead, it shows actions like "Mix," "Inspect," or "Package.", SYSTEM FLOWCHART (Focus: Hardware & Data Flow), Shows how data moves between physical components: servers, printers, sensors, and databases., Maps the relationship between multiple programs, devices, and users in one big infrastructure., Includes high‑level entities like "Cloud Storage," "User Terminal," and "Mainframe.", Used by IT architects to plan network updates or system migrations., Focuses on data pathways and file transfers, not on internal programming logic., DOCUMENT FLOWCHART (Focus: Paperwork & Forms), Tracks the physical or electronic routing of forms, invoices, reports, or signed approvals., Shows who creates, reviews, signs, and files each document as it moves through an office., Often uses symbols for paper copies, multiple copies, and filing cabinets., Used by administrative staff to spot bottlenecks in approval chains., Does not include code, machines, or production lines—just paperwork trails.
