The Challenge: From Sample-Based to Comprehensive Control
For a major French bank, controlling customer-billed fees is a critical regulatory challenge: any undetected discrepancy between fees actually applied and fees due exposes them to legal, financial, and reputational risk.
Before the project, this control relied on manual sampling in Excel, covering less than 1% of files. Within a scope of over 900,000 files, the unverified portion represented an estimated legal risk of over 11 million euros in the event of a dispute.
The challenge was twofold: to transition from sample-based control to comprehensive control, and to ensure rapid adoption of the solution by non-technical teams, without prolonged reliance on the consulting firm.

Our Approach: Industrialized Control, Operated by Business Teams
Prime Analytics designed and deployed an automated control framework on Alteryx, structured around three key principles:
1. Comprehensive Coverage
Migration from manual sampling to systematic 100% control of in-scope files. Complex reconciliations, joins, and calculations automated into reproducible workflows.
2. Rapid Adoption by Risk and Control Teams
Workflows designed to be maintained and extended by the teams themselves. Coaching and training program to build technical autonomy before the end of the engagement.
3. End-to-end Auditability
Each control is traceable, reproducible, and defensible to the regulator or in the event of a client dispute.
Before / After
Industrialization enabled the Risk teams to transition from symbolic coverage to a robust, comprehensive, and defensible control system.
• Coverage : increased from less than 1% of files to a comprehensive control over 100% of the scope — meaning 900,000 files processed per cycle. went from 6 man-days to by report and by entity — a production ratio divided by 50.
• Tooling : replaced Excel and ad-hoc processes with auditable Alteryx workflows, reproducible and defensible to the regulator.
• Production Cycle : reduced from 24 weeks to 6 weeks — a report produced four times faster.
Technical Dependency : moved from a strong reliance on experts to autonomous business teams, trained and capable of operating the system themselves.
• Undetected risk : reduced from an exposure of over 11 million euros to a risk now identified, documented, and managed.
— When the manageable scope expands from a few thousand to 900,000 files, the business operates on a different scale. A system now defensible to regulators, in every cycle.

A sustainable control system, operated autonomously
The control system was deployed and went live in a few weeks: 900,000 files are now comprehensively verified in each cycle (compared to less than 1% by manual sampling previously), the production cycle was cut by four — from 24 to 6 weeks — and discrepancies detected in the previously uncovered scope helped mitigate a legal risk estimated at over 11 million euros. Beyond this performance, the project delivered an end-to-end auditable system, defensible to regulators, operated autonomously by the Risk teams, and now applied to other types of controls. The project not only revealed a hidden risk — it transformed the Control function's approach.
We transitioned from sample-based checks to comprehensive control. For a matter with regulatory implications, this change of scale is exactly what we expect from a partner.“With Prime Analytics, we were able to get this project up and running in just a few days. Their knowledge of Alteryx and their technical expertise allowed us to move quickly and obtain greater precision than we expected. This model has made us gain in reliability, speed and autonomy.”
