Start when a rate invites a story

A drop between two funnel steps is an observation about recorded events, not a diagnosis. Even a smooth sequence can conceal readers who misunderstood an offer and completed the wrong action. Write the signal precisely: denominator, numerator, time range, eligibility rule, tracking changes, and uncertainty. Then list at least three rival mechanisms. A person may have received enough information to leave, failed to comprehend the next step, distrusted a claim, encountered a technical error, or continued outside the measured channel. The first diagnostic discipline is refusing to call every non-conversion 'friction.'

Check whether the map starts and ends too late

If the journey begins at the landing page, upstream message mismatch disappears from view. If it ends at the purchase, onboarding trouble and refunds disappear. GOV.UK's experience-mapping guidance spans the period from need through use, making it a useful corrective to page-bound analysis. Extend the diagnostic window one meaningful decision before and after the measured step. Look for different promises in search snippets, social posts, email, affiliate pages, merchant checkout, confirmation, and support. A handoff may be broken even when each owner reports acceptable performance inside their own boundary.

Use behavior to separate five failure classes

Create a table with measurement, comprehension, trust, effort, and fit. For measurement, inspect missing events and cross-domain loss. For comprehension, ask people to explain the offer and consequence in their own words. For trust, observe which evidence or policy they seek. For effort, watch errors, waiting, repeated entry, and unavailable recovery. For fit, learn whether the reader appropriately rejects the option. Journey maps can organize these observations, but a composite picture cannot establish frequency. Preserve individual paths long enough to see whether the same surface exit comes from different causes.

A healthy exit has clarity and agency

Do not optimize away an exit simply because it lowers a dashboard rate. An informed person who learns that the product lacks a required feature is evidence that qualification worked. A harmful exit looks different: material cost appears only after commitment, the back path loses work, cancellation cannot be found, or the person cannot tell whether an action succeeded. Government Communication Service guidance encourages attention to customer reactions across contacts. Use direct research and support records to examine those reactions, while avoiding the claim that frustration was caused by one element unless the observation can separate alternatives.

Choose a discriminating observation

Match each hypothesis to evidence that would differ if it were true. If tracking loss is suspected, reconcile server, merchant, and client events. If ambiguity is suspected, run short task-based comprehension sessions. If trust is suspected, review search behavior and ask what proof was missing. If technical effort is suspected, reproduce the path on representative devices and assistive technology. Set a small sample or time box appropriate to learning, not to claiming population uplift. Stop when one mechanism is sufficiently supported for a reversible fix, or when the decision must remain uncertain because the available evidence cannot distinguish causes.

Close with a hypothesis tree, not a new funnel picture

Document the original signal, competing explanations, evidence for and against each, affected reader groups, and the next check. Link every branch to an owner and a reconsideration trigger. A useful result may be 'instrumentation cannot support this conclusion' or 'the exit is mostly appropriate,' not necessarily a redesign. If a fix proceeds, state the intended mechanism and guardrails such as complaints, refund requests, accessibility failures, and support load. This prevents a local conversion gain from being mistaken for a better end-to-end journey and gives the next review a falsifiable starting point.
