About

Case Study
Cross-System Regulatory Reporting Automation
An anonymized, low-intrusion workflow for recurring operational reporting that works with existing business systems and legacy DBF-compatible output.
The previous daily routine involved manual extraction, consolidation, and validation across disconnected sources and typically took 50–60 minutes.
The assisted workflow aggregates data, maps fields, converts formats, and applies validation while staff keep using their existing tools.
The more-than-70% reduction is an internal operational estimate comparing the former manual routine with the assisted production workflow.
