From manual reports to a self-service analytics culture at country scale

500+ stakeholders1,000+ platform users#1 Tableau adoption EMEA/APAC60% less manual effort
Problem
Hundreds of Excel reports maintained by hand, the same numbers rebuilt week after week into PowerPoint decks for country leadership — one team carrying all business reporting, advanced analytics and models for the consumer business, with no capacity left for the work that actually grows the business.
Scale
The country's entire consumer banking business — 500+ business stakeholders and 1,000+ platform users across EMEA / APAC.
Action
As business owner of the country's data warehouses and Tableau, I built the Medallion Gold layer (2019, ahead of widespread industry adoption) as a single trusted foundation, automated 100% of business reporting with RPA and Tableau, and replaced hand-built leadership decks with decision-grade self-service dashboards.
Result
Shifted the consumer business to data-driven decision-making, cut manual effort by 60%, and earned the #1 Tableau adoption culture across EMEA / APAC.

The win was cultural, not technical: stakeholders moved from assembling numbers to acting on them.

What I changed

1. Business ownership of the platforms. As business owner of the country’s data warehouses and Tableau, I held the authority and accountability to change how the consumer business worked with data.

2. An early architecture bet that made everything else possible. Medallion Architecture was just emerging in the industry when, in 2019, I brought it into the organisation and built the Gold layer, the trusted foundation that became the backbone for analytics across the consumer business.

3. Eliminating manual reporting. We automated 100% of business reporting (RPA and Tableau), built 2,000+ automated data streams, and cut manual effort by 60%.

4. From hand-built decks to decision-grade dashboards. The region offered Tableau as an optional capability; I made it the standard for the consumer business. We replaced the weekly PowerPoint decks that product and sales teams rebuilt by hand with dashboards leaders used to make real business decisions, and gave product teams answers fast enough to accelerate their decisions and time-to-market.

5. A cultural shift at scale. Moved 500+ business stakeholders from manual weekly reporting to strategic, data-driven decision-making, and earned the #1 Tableau adoption culture across EMEA / APAC.

Speed — before → after. From a leadership deck rebuilt by hand every Friday for the noon meeting to trusted numbers refreshed daily by 10 AM, on their iPhones. A year earlier, this was unthinkable.
