✺ The work

How we delivered

In Australia’s fiercely competitive retail banking sector, this Big Four bank’s product leadership team was drowning in reports that delivered volume, not value. Legacy BI outputs were fragmented, inconsistent, and failed to connect customer behaviours to product decisions, investment ROI, or profitability.

Step 1: Comprehensive Data & Reporting Audit

We mapped existing BI reports, data warehousing architecture, and ETL processes; assessed quality, timeliness, and value-add; and interviewed stakeholders to identify gaps between available data and real decision needs.

Step 2: Radical Data Transformation & Insight Innovation

We created the retail bank’s first “Customer Balance Sheet” — a single synthesised view quantifying the customer-quality impact of every product investment and pricing decision, delivered directly to the Consumer Bank CEO.

Step 3: Building a Systematic Customer Intelligence Platform

  • Systematic onboarding intelligence
  • Share-of-wallet growth models
  • Proactive retention engine
  • Integrated dashboards and automated reporting

Results

  • CEO-level strategic clarity
  • Significantly improved product and service experiences
  • Stronger onboarding, share-of-wallet growth, and retention
  • Elevated data maturity and profitability focus
