• Design and define customer segmentation strategies for targeted campaigns and customer lifecycle management.
• Own use cases end to end, including churn, retention, dormancy, win-back, upsell, tariff migration, and device upgrade.
• Define customer base management strategies and identify high-value customer segments.
• Design campaign targeting criteria and ensure segments are practical and commercially actionable.
• Work with customer data and campaign management platforms to build and activate segments.
• Define measurement frameworks for campaign performance, customer response, and incremental impact.
• Design control groups and measurement approaches to evaluate campaign incrementality.
• Analyze customer behavior and identify opportunities for retention, cross-sell, upsell, and reactivation.
• Work closely with engineering and data teams to specify required customer attributes, segment logic, and data definitions.
• Challenge unnecessary segmentation and prioritize use cases that can be practically activated and measured.
• Ensure customer segments have clear business definitions, eligibility criteria, and measurable outcomes.
• Support the development of reusable customer data and campaign use cases across banking products and customer journeys.
• Translate analytical insights into clear requirements for campaign and customer data teams.
