Session stitching without fairy tales
Users hop from phone to tablet mid-checkout. Payment apps interrupt sessions. QR handoffs spawn new device IDs. If your Customer Journey Analytics for Apps model assumes a single continuous session, you will invent drop-offs that never happened — or hide ones that did.
Stitch with confidence tiers
We teach three tiers: hard keys (authenticated user id), soft keys (probabilistic device graphs), and honest gaps (unknown). Scorecards should show how many paths sit in each tier. Executives can handle uncertainty when you visualize it; they punish surprise later.
Thailand-specific interruptions
Banking deep links and LINE handoffs frequently reset session containers. Treat those transitions as first-class edges in your path model rather than noise to filter out.
What not to do
Do not average across confidence tiers into one “completion rate.” That number becomes a political weapon disconnected from instrumentation reality.
