The idea

A task flow describes the steps inside a product; a journey includes what happens before, after, and across channels. To improve a repair request, map how the tenant notices the problem, reports it, learns whether the request was received, receives a visit time, and checks whether the issue was resolved. Each handoff creates a question: who owns the next step and what does the tenant know?

Draw a successful path and at least one interrupted path. Include delayed service, an unavailable appointment slot, a missed visit, and a request that must be escalated. Record information the tenant should not have to enter twice. A good flow makes state and ownership understandable even when the work leaves the app for a technician or call center.

A common mistake

A shorter sequence of screens is always a better journey. Removing steps can hide essential confirmation, consent, or recovery.

Worked example

Fictional scenario

A tenant reports a broken heater through a housing-service app.

An expert maps a repair report through submission, triage, scheduling, and completion. They notice that the app says 'Done' at submission even though triage can reject missing details. They relabel it 'Request received,' show the next review step and a way to add information, then test whether tenants understand the service state.

Guided decision

Which flow would you prototype first for a repair request that requires staff triage?

Choose the option you would try first

Independent application

Fictional scenario

A worker books a shared electric vehicle through mobile, then unlocks it with a physical terminal.

Map the journey from selection to return, including failed unlock, low battery, and handoff to support. Identify the information that must travel between app and terminal.

Make: A journey and task-flow diagram with at least one recovery branch and ownership notes.

Review your work against this criterion

The map includes cross-channel handoffs, honest state transitions, and a recovery route tied to the worker's goal.
