How to generate a process flow diagram

Tips on making a Process Flow Diagram

• Instead of writing a prompt from scratch, consider pasting excerpts from existing process documentation, SOPs, knowledge base articles, or meeting notes.
• Working with an LLM to create a fleshed out diagram prompt can be effective. Ask it to organize the process as a sequence or nested list, and call out roles, steps, and decisions clearly.

1. Write a prompt describing the business process

A simple one-liner can work too but the best prompts are usually at least 3–4 sentences long. Applying the below framework generally yields good results:

• Start by listing the major steps in the process. Describe what happens at each stage from beginning to end.
• Include the roles or systems involved in each step. (e.g. HR team submits form, Finance reviews expense).
• Highlight decision points and alternate paths. Include branching logic to reflect “if-then” scenarios in the process.

2. Make a diagram with the completed prompt

3. Edit the diagram with follow-up prompts (this step requires signing in to Eraser)

4. Manually adjust the layout using GUI controls (this step requires signing into Eraser)
