Jitera for undocumented software and fault investigation

Hitachi Construction Machinery used Jitera to explain undocumented software and investigate faults

WorkingVendor case studyVendor ↗

Problem

A small engineering team maintained systems supporting quality assurance. Some programs had no documentation after their developers' contracts ended, and fault investigation required manually tracing code.

Approach

The quality DX team adopted Jitera because it could read an entire repository. Engineers used it to explain existing programs and prepare documentation drafts. They also supplied error details and source code, then questioned the AI about possible causes.

Results

No published figures

Takeaway

Repository access gave the team a way to recover knowledge missing from its documentation. The vendor reported faster work without a numerical comparison.
