Every council has a beautiful journey map somewhere. Post-its, personas, pain points in red.

And a year later, the service works exactly as it did before.

The journey map shows where residents struggle. It rarely shows why; the hand-offs, the re-keying, the three systems nobody wants to own. So operations can’t act on it, and finance can’t cost it.

This is where process mapping earns its place in the service designer’s toolkit.

Map it live, with the people who do the work. Tools like Engage Process let you build the “as-is” process in the workshop, with frontline staff or “subject matter experts” correcting it as it takes shape. No redrawing afterwards. No week-long validation loop. The people in the room own the map.

One model, two views. Show members the clean resident journey. Flip to the full swimlane view with back office and IT. Same model, so the front stage and backstage never drift apart.

Do the uncomfortable maths. Add time, cost, roles and systems to each step, and “this journey is frustrating” becomes hours lost and hand-offs that don’t need to exist. That’s the language a business case speaks.

Leave something that lasts. A maintained process map becomes the handbook for onboarding, training and continuous improvement, and the thing that stops a redesign quietly unravelling.

Don’t start from scratch. Other councils have already been here. Southwark’s Local Digital work found 20 councils had used Engage Process over two years to map and improve processes on targeted discovery projects, across services like social care, finance and environment. Shared patterns beat blank canvases.

And if you’re facing LGR, this is how you harmonise properly. Map the same service across each predecessor council, compare the variation and cost, and design one model on evidence – not on whichever council happens to be biggest.

Service design gets residents into the conversation. Process mapping gets the organisation to change.
