Case Study: a leading global tier 1 bank achieves 95% faster documentation and 500% ROI with GFT's Wynxx

One Leading Global Tier 1 Bank cuts documentation time by 95% with GFT

The customer, a leading global Tier 1 bank, faced significant challenges in understanding and maintaining its complex legacy systems. Senior engineers were spending up to four weeks manually documenting a single application, which slowed modernization and risked the loss of valuable expertise. The bank partnered with vendor GFT to address this using their flagship GenAI platform, Wynxx.

GFT implemented Wynxx, a generative AI platform that automated the analysis and documentation of the bank's legacy Java code. Using Google Cloud Vertex AI and Gemini 1.5 Pro, Wynxx generated architecture diagrams and functional summaries in minutes instead of weeks. This solution delivered a 95% reduction in documentation time, €300,000 in value in a single day, and a 500% ROI within the first month for the bank, as measured by GFT.
