BI Transformation for a Fashion Retail Giant
A UK-based fashion retailer with eight decades of heritage, running 250+ stores across the UK and Europe and controlling everything from design and manufacturing to distribution.

Technologies Used
The Challenge
The client's BI stack — Oracle, Looker, SAP Business Objects — was costly, hard to scale, and falling behind modern reporting needs. There was no single verified source of business truth across corporate systems, daily BI report work was largely manual, and decision-makers lacked the visualisation tools to act on data quickly.
The Solution
We kept the legacy stack running smoothly through the transition, then layered in Microsoft Power BI for modern, user-friendly reporting. A Data Vault 2.0 architecture with a Snowflake mart layer became the single source of truth across all corporate systems. From there, we automated the most repetitive BI report work and introduced advanced Power BI visualisations so teams could read and act on data at a glance — delivering dedicated data marts for the Trading, Commercial Finance, and Product teams along the way.
The Results
- 40% efficiency improvement — automation cut report generation time significantly.
- 60% enhanced data accuracy — a true single source of truth eliminated discrepancies.
- 35% increase in user adoption — more employees now rely on BI tools daily.
- 25% operational cost savings — reduced dependence on legacy systems.
- 15% better decision-making — faster, more confident strategic calls.
