How to generate a workflow diagram

Tips on generating a Workflow Diagram
  • Start with existing documentation – Pull steps from SOPs, project plans, onboarding manuals, or stakeholder interviews. This saves time and ensures accuracy.
  • Use an AI assistant to organize your thoughts – If the process is complex, prompt an LLM to outline the phases and tasks first. For example: “Break this into workflow stages and tasks by role.” This helps you generate a clean and complete prompt before feeding it into the diagram tool.
  1. 1

    Write a prompt describing the workflow

    Aim for 3–4 sentences or a structured outline. Include:

    • Phases or stages – Identify the key stages of the workflow (e.g. “Request Submission”, “Manager Review”, “Final Approval”).
    • Tasks within each phase – Describe the main actions taken in each stage. You can also include the role responsible (e.g. “HR team verifies documents”).
    • Start and end points – Clearly define where the process begins and ends. For example, “Workflow begins when a form is submitted and ends when approval is granted.”
  2. 2

    Generate the diagram

    using the written prompt. The AI will convert it into a structured, flowchart-style diagram showing the progression of tasks across phases.

  3. 3

    Refine the diagram with follow-up prompts

    (requires signing into Eraser). You can add missing steps, rename items, or clarify task descriptions.

  4. 4

    Manually adjust the layout using GUI tools

    (also requires sign-in). Drag and drop elements to clean up spacing, align nodes, or improve the visual structure.
