A drop-off locates a boundary, not a cause
A transition rate tells you that fewer measured sessions reached the next recorded state. It does not say why. Before diagnosing the experience, verify event definitions, consent effects, bot filtering, cross-domain continuity, releases, denominator changes, and the size of the observed difference. Then state the boundary precisely: which people, task, context, and period are affected? Compare adjacent transitions and unaffected segments. A broad decline across unrelated tasks suggests instrumentation or environment; a narrow decline after one validation step suggests a different search. The correct first output is a symptom card with uncertainty, not a story about motivation.

Failure pattern one: people cannot form an accurate prediction
Look for incorrect summaries of price, eligibility, delivery, data use, cancellation, or what the action will do. Long dwell time can be reading, confusion, comparison, or interruption, so it is only a weak clue. Stronger evidence comes from task observation, repeated clarification questions, backtracking between terms and action, and support language that names the same uncertainty. The next separating observation is a comprehension probe: after natural reading, ask what will happen next and what commitment is being made. If people answer accurately yet leave, move understanding down the ranking rather than making the copy louder.

Failure pattern two: the interface creates avoidable work
Signals include repeated field corrections, re-entered information, unnecessary account creation, loops between steps, and valid work lost after an error. Separate effort from technical failure: a form may operate exactly as designed yet demand information people do not have. Inspect task sequence and error distribution, then reproduce the path with realistic constraints such as small screens, password managers, assistive technology, and a slow connection. GOV.UK's error guidance emphasizes telling people what went wrong and how to fix it. If the message is clear but the policy demands an unavailable document, the mechanism is requirement burden, not error wording.

Failure pattern three: operation degrades in the field
Technical friction may appear as delayed responses, layout movement, unresponsive controls, duplicate submissions, compatibility errors, or state lost during navigation. Pair error and release logs with real-user performance distributions. Core Web Vitals offer shared signals for loading, interaction responsiveness, and visual stability, but passing thresholds does not prove the task works and a poor metric does not prove it caused a particular exit. Segment by route, device, geography, and version; reproduce the affected state. The discriminating check is whether the failure and the abandonment co-occur in the same context and diminish when operation is repaired.

Failure pattern four: the reader lacks justified trust
Trust should not be inferred from a single survey score. Look for late searches for company identity, returns, privacy, evidence, or reviews; objections that recur in support; and exits when terms finally become visible. Distinguish missing evidence from a rational dislike of the evidence presented. Adding testimonials cannot repair an unfavorable cancellation policy, and moving a disclosure cannot make a weak claim true. Use a moderated decision task or short intercept to learn which uncertainty remains, then verify it against observable page content and downstream outcomes. The test is whether clearer, substantiated information improves prediction without hiding an important cost or limitation.

Failure pattern five: leaving is the correct fit decision
Some people should not proceed because the offer is too expensive, mistimed, ineligible, risky, or inferior for their situation. An informed exit can demonstrate clarity rather than friction. Compare stated needs with product boundaries, cancellation and refund behavior, qualified completions, and post-purchase regret. If removal of a warning increases orders but also increases refunds and support distress, the page did not become healthier. Close the diagnosis with a ranked table: mechanism, supporting signal, conflicting signal, next observation, owner, and reconsideration date. Change the experience only when evidence identifies a preventable mechanism; otherwise improve audience fit or accept the honest exit.
