Every business runs on processes — a customer places an order, a supplier sends an invoice, a manager approves a budget. When a process exists only in people’s heads, it’s hard to improve, hard to train new staff, and hard to find what went wrong. This chapter shows you how to draw clear, standard maps of any business process using Business Process Model and Notation (BPMN) — a visual language that turns messy, real‑world workflows into diagrams everyone can understand.
