As of 13 August 2026, AI can create a swimlane process diagram.

What to actually do

1. Use a tool built for this

   The route this page recommends

2. Do it yourself

   Second choice

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open the current SOP, work instruction, ticket notes or process documentation, and copy the source material for the workflow into one working document.
   2. List every lane involved, including teams, individual roles, suppliers, customers and systems, then mark which role performs each action.
   3. Add the trigger, end state, decisions, approval points, rejected cases, repeat steps, escalations and hand-offs that are missing from the source text.
   4. Paste the completed process information into the prompt and ask the chatbot to produce both the step table and Mermaid flowchart code.
   5. Copy the Mermaid code into a Mermaid-compatible editor or diagramming tool, then export or redraw the result in the format your team uses.
   6. Ask the process owner and one person who performs the work to compare every step, lane, branch and exception with a real recent case, and amend the diagram before publishing it in the SOP repository.

   Prompt

   Create a swimlane process diagram for the workflow below.
   
   Process name: [name]
   Purpose: [what the process achieves]
   Start event: [what triggers it]
   End event: [what completion looks like]
   Lanes or roles involved: [list every team, role, supplier, customer or system]
   Process description and steps:
   [paste the full workflow, including who performs each action]
   Decisions and rules:
   [paste each decision and the outcome for every possible answer]
   Exceptions and rework:
   [paste failures, rejected items, repeat steps and escalation routes]
   Systems, documents and approvals:
   [list them]
   
   Do not invent steps, owners, rules or approvals. If the information is missing or contradictory, mark it as [NEEDS CONFIRMATION] and ask a concise question. Put each action in the lane of the person, team or system that performs it. Show hand-offs, decision points, loops, parallel work and end states. First provide a compact table with columns: step number, lane, action, input, output, decision or hand-off. Then provide Mermaid flowchart code using subgraphs as swimlanes, with readable node labels and labelled decision branches. Keep the diagram faithful to the supplied process rather than improving it. Finish with a short list of assumptions and unresolved questions.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
