Infrastructure for Client Risk & Churn Prediction

The predictive model requires explicit definitions of what constitutes "churn risk" behaviors, "financial distress" signals, and "fraud" patterns. These must be documented with clear criteria - not "clients who seem unhappy" but "clients with transaction frequency decline >40% over 60 days + balance reduction >30% + increased service inquiry volume." Without explicit risk definitions, the ML model trains on noise and generates false positives that overwhelm retention teams.

This capability requires automated, continuous capture of behavioral signals from transactions, logins, service inquiries, and external events. Manual logging (L2) or even template-driven capture (L3) is too slow - by the time someone manually logs "client seems unhappy," the churn event has already occurred. The model needs event-driven capture: every transaction logged, every login tracked, every service inquiry captured with sentiment - in real-time.

ML models require formal feature schema defining Client behavioral attributes, temporal patterns, and risk labels. Without explicit ontology mapping Client → TransactionPattern → ChurnRisk WITH calculation rules (e.g., TransactionFrequency.Decline = (Transactions.Last60Days - Transactions.Prior60Days) / Transactions.Prior60Days), the model can't compute consistent features. This isn't organizing data - it's defining computable relationships in machine-readable form.

The model must access real-time or near-real-time data from transaction systems, digital banking platforms, CRM, call center, and external data feeds. Batch exports (L2) mean the model predicts yesterday's risk, too late for intervention. API access to most systems (L3) isn't enough - need unified access layer pulling consistent client behavioral context from all sources simultaneously for real-time scoring.

Client behavior evolves. Market conditions shift. What predicted churn in 2023 doesn't predict churn in 2025. The model requires continuous retraining (monthly at minimum) on recent outcomes, near-real-time feature updates (hourly for transaction/engagement data), and immediate model swaps when performance degrades. Running a 12-month-old model generates predictions based on obsolete behavioral patterns - false positives overwhelm and true positives are missed.

This capability requires integration platform unifying data from core banking (transactions), digital channels (engagement), CRM (profile), call center (sentiment), and external sources (market events). The model needs composite client view assembled in real-time - not querying each system separately. Integration platform orchestrates data flows, ensuring consistent client behavioral profile available for continuous scoring.
