First Principle: Journeys Break at Handoffs, Not Steps
Failure concentrates where ownership changes — team to team, channel to channel, human to AI — not inside the steps each owner polishes.
Steps have owners; transitions don't. Failure concentrates where ownership changes — team to team, channel to channel, human to AI — because the customer's context must cross a boundary that nobody's incentives cross. Map journeys by their seams, not their stages.
Organizations are structured vertically — marketing, sales, onboarding, support — while journeys run horizontally across them. Every boundary between two owners is a place where the customer's context must be carried across by someone whose incentives stop at the boundary.
Each team's dashboard is green; the customer experiences one journey with a crack down the middle.
Illustrative pattern: sales closes with rich notes about the customer's constraints and goals. Onboarding starts with a blank template and asks the customer to explain their business again. The third time a customer repeats themselves, they read it as the company not listening.
- Map the journey by its transitions, not its stages.
- At each handoff ask: what context crosses, what dies, and who owns the seam?
- Give every seam an owner and a definition of a clean handoff.
Apply this
Reading about first principle: journeys break at handoffs, not steps is one thing. Seeing where it applies in your journey is the useful part.
