Real-time customer data is not a faster warehouse query. This report maps the separate operating path required to capture events, resolve identity, make a decision, and act before the moment passes.
Batch analytics asks what happened and what patterns exist. Real-time decisioning asks what should happen now.
Durable customer history, governed models, and analytical truth often remain in the warehouse. The real-time layer should selectively bring the required context into the live path.
Anonymous events, accounts, devices, households, and logged-in users must be connected carefully. Over-aggressive identity stitching creates privacy and relevance failures.
Choose a use case with a short value window, such as next-best action, fraud intervention, inventory urgency, or in-session help. Define the exact action and target user.
Allocate time across collection, transport, identity, enrichment, decisioning, and activation. Instrument every stage and define the fallback when a dependency is slow.
Separate durable profile attributes, session state, features, consent, and channel eligibility. Make the source and freshness of each field visible.
Keep event history and decisions so teams can replay, audit, and compare treatment with control. Real-time systems need analytical proof after the moment passes.
Usually not. Add a live decision path where the current platform cannot meet latency or control requirements.
It can provide history and sometimes low-latency queries, but same-session decisions often need cached state and streaming evaluation.
Start from the business moment. A web interaction may need hundreds of milliseconds; an operational workflow may tolerate seconds.
Incorrect identity or consent, because it can make a technically fast system harmful.
Run controlled experiments and measure incremental conversion, retention, resolution, or risk reduction.
