About the client
The client is one of North America’s largest banks, providing a wide range of financial services, including personal and retail banking. They serve over 20 million personal banking and branded card customers, along with 46 retail partner clients across their North American operations.
Business goals and objectives
The contact center modernization initiative focused on achieving three key strategic objectives:
- Enhancing customer satisfaction and experience: The primary goal was to elevate customer satisfaction (CSAT) and improve the Net Promoter Score (NPS) by delivering superior customer experiences.
- Migrating to a modernized technology platform: Transitioning from traditional telephony systems and legacy platforms to a robust technology stack was pivotal. The target infrastructure enables lean service implementation and operational excellence through AI-driven operations management. Features such as agentic AI and self-service capabilities empower end-to-end management across channels, boosting efficiency and scalability.
- Optimizing operational costs and efficiency: The initiative aims to reduce operational (OPEX) and infrastructure costs significantly while maximizing the impact of human capital. Improved efficiency in business process management (BPM), zero call wait times, and reduced average call handling time (AHT) for agents are central to this objective.
