warning The Challenge

Banks with long operating histories often hold rich customer and behavioral data but struggle to operationalize it into consistent, timely personalization due to data silos, legacy decisioning, and limited model deployment pathways. Without scalable ML operations, personalization remains episodic, and communications can be generic, poorly timed, or misaligned to customer need—reducing engagement while increasing fraud exposure and service demand. The business challenge is to translate legacy data into controlled, compliant, repeatable decisioning at scale.

psychology The Solution

NatWest implemented machine learning-driven personalization using Amazon SageMaker as a foundation for developing and deploying models, with an emphasis on scaling the number of models in production. A COI-standard implementation typically requires a pipeline for feature management, governance for model approvals, and monitoring for drift and bias—especially in regulated communications and risk-adjacent use cases. The reported approach emphasizes production deployment rather than experimentation, positioning ML as a bank-wide capability for customer engagement and wellbeing outcomes.
