Case Study: Global Product Company accelerates legacy modernization readiness with Gorilla Logic Construct™

Global Product Company cuts engineering work by 30-80% with Gorilla Logic

A Global Product Company faced significant challenges modernizing its business-critical legacy system built on outdated RPG code. The system lacked documentation and clear ownership, which constrained engineering velocity, increased risk, and stalled transformation efforts. To overcome this, they engaged Gorilla Logic and its Construct™: Chronicle service.

Gorilla Logic implemented an AI-powered workflow using GPT-4o, Claude, and DocuWriter.ai to ingest the RPG code and automatically generate comprehensive system intelligence. The solution delivered program summaries, visual diagrams, and a ready-to-use feature backlog. The results significantly reduced engineer onboarding time, eliminated reliance on hard-to-find subject matter experts, and provided a modernization-ready backlog for immediate engineering execution.
