Leading high street retailer
Retail giant transforms reporting performance and scales to 1,000+ Users
the challenge
Dufrain was engaged by this well known high street retailer to optimize their reporting suite. The goal? To enhance usability, scalability, and performance.
During discovery, platform capacity constraints were identified. Many reports contained redundant visuals and information, bloating the PBIX files. Additionally, the semantic model had numerous duplicate measures, further slowing performance.

the solution
We offered two clear options.
Option 1: A back-to-front approach. We would split models into smaller, report-focused chunks, address upstream and model findings, resolve front-end issues without feature loss, and discuss licensing and best practices.
Option 2: An end-to-end approach. We would take a small slice of the estate, like Retail & Loss TISP, and address findings comprehensively, from upstream modeling to the PowerBI semantic model and report, while implementing best practices.
the outcome
The client selected our back-to-front optimisation approach. By moving complex DAX logic into SQL and building multiple semantic models, we streamlined their reporting landscape and eliminated unnecessary visual complexity.
The result was a leaner, more scalable reporting suite that dramatically reduced refresh times, improved usability for over 1,000 users, and delivered measurable performance gains, including a 70% cut in compute usage and 52% faster report generation.
