Service Designer

Your service, mapped and scored against what good looks like.

Service Designer turns policies, process maps and call scripts into a blueprint, journey and flow, then scores the service against Lou Downe's 15 principles of good service.

The problem

  • The service lives in twenty documents and five organisations.

  • Nobody agrees what good looks like, so debates go round in circles.

  • Blueprints take weeks, and the gaps are hidden.

What it does

  • Extracts actors, channels, touchpoints and backstage steps with sources

  • Drafts an ecosystem map, service blueprint, journey map and service flow

  • Scores all 15 good-service principles on a 0–4 scale, with evidence

  • Names a fix and an owner for every weak principle

  • Builds boards in Miro, Mural or FigJam after your yes

How it works

  1. Get this on Gumroad and download the zip.

  2. Unzip it into a project folder and open it in your AI tool.

  3. Say `map the service in <documents or description>`.

  4. It works one stage at a time and stops for your yes.

  1. Extract

    Stakeholder and touchpoint extraction

  2. Map

    Ecosystem map, Service blueprint, Journey map and service flow

  3. Score

    Good service scorecard, Canvas write

Built to a standard

Lou Downe's 15 principles of good service, scored 0–4.

Every claim cites its source. Nothing is written to your tools without your approval.

Who it is for

Service owners, delivery managers and product owners who have lots of documents and no service designer to hand.

What you need

  • An AI tool that reads project instructions: Claude Code, Cursor, or a tool that reads AGENTS.md. Claude Projects and custom bots work too, with copy-and-paste outputs.

  • Your own AI subscription or API key. Nothing to host.

  • Optional

    Optional connections: Miro MCP, Mural MCP, FigJam via Figma MCP.

Questions

Does it replace service designers?
No. Service design is negotiation. Service Designer prepares the ground; people negotiate.
Do I need Miro?
No. Without a canvas tool you get Mermaid diagrams and tables.
What is the 0–4 scale?
From 0, not possible for users, to 4, all users can do it easily and consistently.
Can I change the files?
Yes. They are plain markdown. The licence lets you adapt them for your own work.

Designed before it was built

Designed before it was built

This agent was designed with the five-question method: purpose, boundaries, what it touches, when a person steps in, and how you know it works. [Read the design](./anatomy).
