What Is a Process Diagram?
Process diagrams show steps in a process — how something is manufactured, how something works, or how something happens in nature.
Common types:
Key Difference from Graphs
Process diagrams don't show data or trends. Instead, you describe:
Structure
Step 1: Introduction (1 sentence)
"The diagram illustrates the process of converting solar energy into electricity."Step 2: Overview (1-2 sentences)
"The process consists of six main stages, beginning with the collection of sunlight and ending with the distribution of electricity to homes."Step 3: Body Paragraph 1 (5-7 sentences)
Describe the first half of the process.Step 4: Body Paragraph 2 (5-7 sentences)
Describe the second half of the process.Process Language You Must Know

Example: How Chocolate Is Made
Introduction: "The diagram shows the stages involved in producing chocolate from cocoa beans."
Overview: "The process consists of seven main stages, from harvesting the raw cocoa beans to packaging the final chocolate product."
Body 1: "Initially, cocoa beans are harvested from cocoa trees. The beans are then fermented for several days. After fermentation, the beans are dried in the sun for about a week. Next, the dried beans are packed into bags and transported to the factory."
Body 2: "At the factory, the beans are roasted at high temperature. The roasted beans are then ground into a paste. Finally, the chocolate paste is moulded into bars and packaged for sale."
Common Mistakes
- Using "I think" — Process diagrams are descriptive
- Not using passive voice — "The beans are harvested" not "Workers harvest the beans"
- Mixing up the order — Follow the process step by step
- No overview — Always summarize the process
Practice
Take any process diagram and write a full Task 1 response. Focus on sequencing words and passive voice.
